Performance Task Synopses

Directions:

1) Brainstorm three or four possible Performance Tasks.

2) Write a brief synopsis (1–2 sentences) for each selected task and list the tasks in a “learning progressions” sequence.

3) Include the standards code for each task.

Task1:

Phenomena: How is it that you can fine the same particles in an element, a compound, and a mixture but they look different in real life and on a model? Jr. Chemist, today you will be following the procedure to complete the task of creating a poster that models the structures of elements, molecules, compounds, and mixtures using marshmallows and toothpicks. Let’s show our reading, modeling, and analytical skills! (S8P1a, S8P1e) Task 2: Phenomena: Have you ever eaten a popsicle on a hot day, to find most of the ice turn to liquid and fall on the floor? Today Jr, Chemist you are going to investigate what happens when things change state. Did you know that at room temperature an element will be a solid, liquid or gas. You are going to develop a model (diagrams and drawings) to explain how thermal energy can be used to change the state of a substance from a solid to a liquid and a gas to a liquid. You will need to demonstrate your knowledge of particle motion and energy transfer. (S8P1.d, S8P2e) Task 3: Phenomena: Who dunnit!? What is it? Science mysteries - in this case using mystery powders. Jr. Chemist you probably know that it is often challenging to determine the identity of an unknown substance based on its chemical and physical properties. A scientist, for example, may only have a small amount of a substance. As a result, the scientist may not be able to conduct all the different types of tests that he or she wants to because some tests may change the characteristics of the sample during the process (such as when a metal is mixed with an acid). Your goal is to use what you know about the physical properties of matter, proportional relationships, and patterns to design and carry out an investigation that will enable you to collect the data you need to determine the identity of the unknown substances. (S8P1c) Task 4:

Phenomena: Chemistry Phenomenon – Effervescence in Chemical Reactions

Jr. Chemist, we need for you to use what you know about physical and chemical properties of matter, stability and change, and how to design and carry out an investigation to develop a set of rules you can use to distinguish between a chemical change and a physical change in matter. The guiding question of this investigation is, What set of rules should we use to distinguish between chemical and physical changes in matter? (S8P1d) Task 5: Phenomena: Static electricity attracting and repelling plastic bag strips. Your next task applicants are to explore different reactions that relate to your element. Explain whether you think it is worth creating a compound of your element or not, using evidence to support your



10

argument. Explain how you think the compound might improve or worsen the ability of your super hero. (S8P1.a-f) Task 6: Phenomena: If your new breed of Super Hero could have one super power, which is chemically fused to an element of the periodic table what would it be and why? Ok, applicants for the Jr. Chemist position at The DCSS Institute for Molecular Science, let’s see what you know about the periodic table. Create a presentation for my lab assistant to explain what the periodic table is, how the elements of the periodic table are organized, and what the numbers around each element represent. It would also be good if you could select a few elements and share their chemical and physical properties. This will be a walk in the park for most of our top candidates. Create a visual poster to explain what the periodic table is. Remember you will design and engineer a new breed of Super Hero, which is chemically fused to an element of the periodic table, which will help facilitate, improve the safety of and help protect the development of the human race against unforeseen events and circumstances. (S8P1.c, S8P1.e)

Performance Task 1 In Detail

Directions: Describe the task in full detail making the connection to the overall engaging scenario. Check that the task directly reflects the level of rigor for each targeted skill and related concept(s).

Task 1 Student Directions:

Phenomena: How is it that you can fine the same particles in an element, a compound, and a mixture but they look different in real life and on a model? Associated Element: S8P1a. Develop and use a model to compare and contrast pure substances (elements and compounds) and mixtures. (Clarification statement: Include heterogeneous and homogeneous mixtures. Types of bonds and compounds will be addressed in high school physical science.) Engage: Jr. Chemist here is a sorting task for you and a partner that will test your knowledge of compounds, elements, and mixtures. You will collaborate with up to three other applicants in the card sort competition. Each group will have one set of ECM Task Cards and one set of “E” “C” “M” “?” cards to help with categorizing your photo cards that represent an item of an elements, compound, or mixture.



11


Students will sort the items pictured into 4 columns: Elements, Compounds, Mixtures, and “?”. (The “?” category is a temporary place holder for you to discuss further within your group. Talk with your partners support your claim on why you believe a particular card would be in a category. Explore and Explain:

Jr. Chemist, today you and a partner will be following the procedure to complete the task of creating a poster that models the structures of elements, molecules, compounds, and mixtures. Within the procedure it asks that you read the ECM Skill 3 Notes Page one section at a time. If these directions are skipped, the final product cannot be completed accurately. I know you will want to rush and complete the poster; but the reading and obtaining of information from the text is the most essential element of the process. Let’s show our reading, modeling, and analytical skills!

Evaluation: Jr. Chemist, now that you’ve completed your model, let’s analyze your data by answering the pertinent

questions from the DCSS Institute for Molecular Science called the “Marshmallow Molecule

Questionnaire.” Use your model to guide your thinking. Element, Compound, or Mixture Identification Discovery sheet. Elaboration: Elements and Compounds activity Jr. Chemist, how is it that you can fine the same particles in an element, a compound, and a mixture but they look different in real life and on a model? Let’s explore this some more with the Elements and Compound activity.

Elements and Compound Materials Needed - Mixture of your choice - Compound of your choice • Cereals • Sugar • Candies • Salt • Nuts and bolts - Plastic zip lock bags for mixture and compound Procedure 1. Each pair of students should have a bag containing either the mixture or the compound. 2. Separate the substance on the table. Student Analysis 1. Jr. Chemist, it’s now time to explain how you separated your substance. 2. Look around at other groups. Were some groups not able to separate their substances? 3. Talk about why some groups could not separate their substances. 4. Explain how you can differentiate between elements, compounds, and mixtures.

Task 1 Teacher Notes Engage:

1. Each group will have one set of ECM Task Cards and one set of ECM? cards to hold up. 2. Students will sort the items pictured into 4 columns: Elements, Compounds, Mixtures, and “?”.

(The “?” category is a temporary place holder for students to discuss further within their group, all items should be sorted before answers are revealed)



12


3. Once all the groups have had a chance to discuss and sort the items, we will go over the answers as a class.

4. Using the PowerPoint, show the first item (Rocks). Ask each group to choose one of the E,C, or M cards.

5. Have them place the “?” in front of their answer. (this prevents the other groups from seeing their answer) A spokesperson for each group will stand up and hold the ECM? cards.

6. Ask all the groups to reveal their answer at the same time. Compare answers & discuss. 7. Reveal the answer and have students record the results in their notes. 8. If needed, have students move the card to the correct category on their desk, too. 9. For fun, I award a point to each group that has a correct answer; the kids enjoy a little

friendly competition. 10. Continue with the next slide (Copper) and repeat.

Engage:

ECM Sorting/task cards and answers could be laminated and cut apart, 1 set per 2-4 students

E, C. M, ? cards Elements, Compounds, and Mixtures Notes Elements, compounds, mixtures PowerPoint

Task 1 Teacher Notes Explore/Explain: In this lesson, students gain an understanding of what elements, molecules, compounds and mixtures look like at the molecular level. Students use marshmallows to represent atoms and toothpicks to represent bonds. The purpose of the lesson is not for them to learn how to bond, but to notice what the particles might look like in each type of matter. Typically, this lesson requires two days from start to finish. Purchase bags of small assorted colored marshmallows. The brand that is sold locally has bags including yellow, orange, green and pink marshmallows. Take time (or have students help) separate these bags into separate containers by color. I typically go through about 1.5 bags per section. In addition, you will need to provide toothpicks, glue and white 11 x 17 poster paper/construction paper. I have students work in groups of 2-3. Groups any larger than that diminishes the impact of the activity for individual students.

In short, students divide their paper into four sections for "Elements", "Molecules", "Compounds", and "Mixtures". The procedure will explain and take them through exactly how to complete each section, including the shape and number of bonds for each molecule. Students read each section of the notes page as they follow along with the directions and complete each section of the poster. A couple student examples are included below. Following poster creation, students complete a worksheet asking them to identify structural patterns in each type of matter

Common Student Errors:

1. Students can "forget" to include the extra examples at the bottom of each section.

2. Students can fail to use double bonds when needed.

3. Students can fail to connect the salt and water molecules with a toothpick.

4. Students can fail to make water in the shape of a triangle or sometimes place hydrogen at the top

of the molecule instead of the oxygen. Explore / Engage Give each student a copy of the instructions and the skill notes form. Encourage students to read and mark the text and following all directions. Model the folding of the paper, the element section

Task 2

Suggested Phenomena: Why do ice pops melt on a hot summer’s day? What are the states of

matter?

Jr. Chemist, scientists are exploring ways in which they could change the state of your super

hero, so that it may display properties that are typical of solids, liquids and/or gasses. They

are in the process of building a device which will release and absorb energy. The theory being

that If enough energy is released the atoms in your super hero element will move vigorously

until their intermolecular forces break apart causing them to change state from a solid to liquid,

and then a gas. By activating this device to absorb energy from the atoms, they hope that the

changes of state will reverse from a gas, to a liquid and then to a solid.

Associated Standards: S8P1b. Develop and use models to describe the movement of particles in solids, liquids, gases, and plasma states when thermal energy is added or removed.

Task 2: Student Directions:

Warm up: Show students a picture of an ice pop with the prompt: “Why do ice pops melt on a hot

summers day? What are the states of matter?

Have students read “At room temperature an element will be a solid, liquid or gas. Their task is to

create a model to show the state of their element or the one you assign at room temperature and how

the molecules behave within this state.

Show students a periodic table and have them select an element from there or assign them one. One

that they may have heard of before.

Example: I am made from the element mercury. At room temperature, my state of matter is a liquid. I

have the ability to change my form. Mercury is also a metal, giving me strength and electrical

conductivity”

Students must determine whether their element or one you assign is a solid, liquid or gas at room

temperature. They then complete the activity questions. (5-10min)

Read Task scenario” Jr. Chemist, scientists are exploring ways in which they could change the

state of your super hero, so that it may display properties that are typical of solids, liquids

and/or gasses. They are in the process of building a device which will release and absorb

Students, must Develop a model (diagrams and drawings) to explain how thermal energy can be used

to change the state of a substance from a solid to a liquid and a gas to a liquid. They will need to

demonstrate knowledge of particle motion and energy transfer.

Students will have to research what happens when substances change state.

You can provide them with Ipads or give them the lab notes.

Students will share their work in a gallery walk. Provide students the opportunity to leave feedback for

their peers based on the rubric.

RUBRIC: 1.I have a model that shows how particles are arranged in a solid, liquid and gas. (5) They may present their work on a poster, they should have 3 diagrams, showing the particles in a solid liquid and gas. 2.I have explained using diagrams how an increase in thermal energy will result in more movement (kinetic) energy within the particles. Diagram should show arrows representing energy being transferred to the atoms. Lines can be placed around the atoms, to show that they have high energy and are moving more frequently. They could show a solid turning into a liquid and how the particle change their position and behavior 3.I have explained using diagrams how decrease in thermal energy will result in less kinetic energy within particles. Same as above, but they could show a gas turning into a liquid.

Particles with high energy, will slow down and then become less far apart, taking the structure of a liquid. Arrows could be used to show energy being transferred away from the gas 4.I have explained what happens to the particles as it changes from a solid to a liquid. Should have a written description, explaining that as thermal energy is applied the atoms move more vigorously, this enables the atoms to overcome their fixed position. 5.I have explained what happens to particles as something changes from a gas to a liquid. Should explain that when thermal energy is transferred away from the gas the atoms move more slowly this results in atoms moving closer to each other taking the structure of a liquid. 6.My work is well presented and shows time and effort

Task 3

Suggested Phenomena: Who dunnit!? What is it? Science mysteries - in this case using mystery powders. Associated Standards: S8P1c. Plan and carry out investigations to compare and contrast chemical (i.e., reactivity, combustibility) and physical (i.e., density, melting point, boiling point) properties of matter. Task 3: Student Directions:

Engage: Guiding questions: What are the identities of the unknown substances?

Jr Chemist, your task is to design and conduct an investigation with three to four of your peers. In this

investigation, you will have an opportunity to learn about some of the challenges scientists face when

they need to identify an unknown substance based on its physical properties and why it is important to

make accurate measurements inside the laboratory. You will start by reading the Introduction to the

investigation, What Are the Identities of the Unknown Substances?, in a round robin format.

Record pertinent facts in the Know, Questions, and Goal Notes Box Chart that has the potential to

answer the guiding question: What are the identities of the unknown substances? After you have

come to a consensus, check out the Getting Started section of the investigation handout. Use the

questions here to drive your thinking about your investigation. You must determine what type of data

you need to collect, how you will collect it, and how you will analyze it. Finally, you will need to

complete the Investigation Proposal and then submitted to your facilitator for approval. Once approved

you may start your data collection. Remember, you are always thinking like a scientist.

Explore

Guiding questions: What are the identities of the unknown substances?

Jr. Chemist, you are now ready to perform your investigation and collect your data. Remember,

scientist can record qualitative and quantitative data. Accuracy is crucial for this task.

Explain: Initial Argument Once your group has finished collecting and analyzing your data, your group will need to develop an initial argument. Your initial argument needs to include a claim, evidence to support your claim, and a justification of the evidence. The claim is your group’s answer to the guiding question. The evidence is an analysis and interpretation of your data. Finally, the justification of the evidence is why your group thinks the evidence matters. The justification of the evidence is important because scientists can use different kinds of evidence to support their claims. Your group will create your initial argument on a whiteboard. Your whiteboard / chart paper should include all the information shown in Figure 3.2.



22


Argumentation Session The argumentation session allows all of the groups to share their arguments. One member of each

group will stay at the lab station to share that group’s argument, while the other members of the group

go to the other lab stations to listen to and critique the arguments developed by their classmates. This

is similar to how scientists present their arguments to other scientists at conferences. If you are

responsible for critiquing your classmates’ arguments, your goal is to look for mistakes so these

mistakes can be fixed and they can make their argument better. The argumentation session is also a

good time to think about ways you can make your initial argument better. Scientists must share and

critique arguments like this to develop new ideas.

To critique an argument, you might need more information than what is included on the whiteboard.

You will therefore need to ask the presenter lots of questions. Here are some good questions to ask:

• How did you collect your data? Why did you use that method? Why did you collect those data?

• What did you do to make sure the data you collected are reliable? What did you do to

decrease measurement error?

• How did your group analyze the data? Why did you decide to do it that way? Did you check

your calculations?

• Is that the only way to interpret the results of your analysis? How do you know that your

interpretation of your analysis is appropriate?

• Why did your group decide to present your evidence in that way?

• What other claims did your group discuss before you decided on that one? Why did your group

abandon those alternative ideas?

• How confident are you that your claim is valid? What could you do to increase your

confidence?

Once the argumentation session is complete, you will have a chance to meet with your group and

revise your initial argument. Your group might need to gather more data or design a way to test one or

more alternative claims as part of this process. Remember, your goal at this stage of the investigation

is to develop the most acceptable and valid answer to the research question!

Task 3 Teacher Notes:

Physical Properties of Matter What Are the Identities of the Unknown Substances? Purpose The purpose of this lab is for students to apply what they have learned about physical properties of

matter to identify a set of unknown substances. Through this activity, students will have an opportunity

to explore the role of patterns and of scale, proportion, and quantity in scientific investigations.

Students will also learn about the difference between data and evidence and how scientists use

different methods to answer different types of questions.

Please see Teacher Notes for Physical Properties of Matter Lab for complete instructions and ideas.

Task 5 Student Directions: Ok, applicants for the Jr. Chemist position at Bizarre Chemical Institute,

let’s see what you know about the trends on the periodic table.

Phenomena

The periodic table contains a little over 100 elements. The atoms of these elements make up millions of

substances in all matter.

Associated standard: S8P1e Develop models (e.g., atomic-level models, including drawings, and

computer representations) by analyze patterns within the periodic table that illustrates the structure,

composition, and characteristics of atoms (protons, neutrons, and electrons) and simple molecules.

Engage

1. Jr. Chemist, you will need a copy of a periodic table.

http://science.widener.edu/~svanbram/ptable_6.pdf 2. You will share out with class everything you already know about the periodic table. We will have a

scribe to write it on the board, 3. You will be looking at trends on the periodic table, one of which is the reactivity of elements. 4. Discuss with your small group what you think reactivity of the elements mean. 5. Watch the YouTube Video “Reaction (Explosion) of Alkali Metals with Water”

https://www.youtube.com/watch?v=DxzFf1ku6cEhttps://www.youtube.com/watch?v=DxzFf1ku6cE

6. Highlight or circle the element on the periodic table as the reactive properties of each element is

displayed.

7. Discuss with your small group:

http://science.widener.edu/~svanbram/ptable_6.pdf





33


• The trends you recognized in regards to reactivity.

• Where are the most reactive elements located?

• Describe the elements you recognize. 8. Construct an argument concerning the location of the elements on the periodic table and the

reactivity. Explore Jr. Chemist, this is a fun way to introduce the families of the periodic table and their properties. First you will enjoy watching the video clips from Periodic Table Videos (http://www.periodicvideos.com) and the experiments performed by the Chemistry Department at the University of Nottingham.

Secondly, you and your team will conduct research concerning the periodic table. You will find the

location of each family, record the elements for each family, discuss their properties, color code the

periodic table, and discussed any patterns you noticed.

Explain

• Work in groups of four.

• Look at period two on the periodic table, then each member adopts an atom that you want to

be the expert on.

• Determine the reactivity of your atom and decide how you would model “act out” that atom.

• Record your atom’s name, the location on the periodic table (family and period), and how you

are going to determine “act out” its reactivity.

• You will come up in front of the class and “act out” your level of reactivity based on your

position on the periodic table.

• Notice the differences in their reactivity and how it relates to the periodic table.

Elaborate

Jr. Chemist, it’s time to decide which element you are going to use to fuse together with your super hero, you need to get some detailed information about this element. We need to know information such as, What is the atomic number and the atomic structure of the element? (Do not use Helium)

My chosen element is_______________________. The chemical symbol of my element is____ Number of protons in my element________. Number of electrons in my element________

http://www.periodicvideos.com/

http://www.periodicvideos.com/



34


Number of neutrons in my element______.

Chemical engineers and physicists are working around the clock to fuse humans with atoms of varying elements. Build a model of your atom so that scientists can see the atomic structure of the element that you want to create, present your model to the chemical engineers. Your task is to build a 3D model of the atom that is found inside your chosen element.

Task 5 Teacher Notes: Note: It is often confusing for students to see the terms “atom” and “element” used interchangeably as if they are the same thing. Explain to students that an atom is the smallest particle or “building block” of a substance. An element is a substance made up of all the same type of atom. For instance, a piece of

The atomic structure of my element

You will need to draw the atomic structure

of your element. Check out the diagrams in

fig. 1.1; use them to help you draw the

atomic structure of your own element. Use

the space provide to the left.



35


pure carbon is made up of only carbon atoms. This piece of pure carbon is a sample of the element carbon. The people who developed the periodic table could have called it the Periodic Table of the Atoms but they did not have a firm understanding of atoms at that time. Since they were working with actual samples of elements such as copper, mercury, sulfur, etc., they called it the periodic table of the elements. Common Misconception(s) - They don’t understand that all things are made up of combinations of these elements. - They don’t understand that valence electrons are what determines an elements reactivity.

Printable PP Table http://science.widener.edu/~svanbram/ptable_6.pdf Engage

1. Jr. Chemist, will need a copy of a periodic table. 2. On the board list everything students already know about the periodic table. 3. Let them know that you will be looking at trends on the periodic table, one of which is the reactivity of elements. 4. Discuss with your small group what you think reactivity of the elements mean. (A chemical that reacts easily with other substances is considered highly reactive.) 4. Watch the YouTube Video “Reaction (Explosion) of Alkali Metals with Water” https://www.youtube.com/watch?v=DxzFf1ku6cEhttps://www.youtube.com/watch?v=DxzFf1ku6cE 5. Highlight or circle the element on the periodic table as the reactive properties of each element is displayed.

After the video: 6. Explain that the most reactive elements are found in group 1 and they become more reactive as you go down the list. 7. Read down the list to see if anyone recognizes these elements. 8. At the end of the video your task is to construct an argument concerning the location of the elements on the periodic table and the reactivity. 9. Have them follow the elements on the periodic table as the reactive properties of each element are displayed.

Explain

• Using a graphic organizer conduct research or follow the teachers notes and gather information on the Periodic Table Classification. This is an introduction to the families of the periodic table.

Reinforce

• Identify that valence electrons determine an atom’s chemical properties, including reactivity.

• Interpret the arrangement of the periodic table to explain how properties are used to classify elements, including periods and groups.

• Identify Metals, Nonmetals, and Metalloids on the periodic table?

• Compare Metals, Nonmetals and Metalloids using their physical properties?

Elaborate

Warm up: Show an image of an atom on the board. Quick write: what is this image? What are

the different parts? Note the image is not an accurate diagram of an element. It is just to get

students talking about the structure of the atom.

Say “Chemical engineers and physicists are working around the clock to fuse humans with

atoms of varying elements. You will build a model of your atom so that scientists can see the

atomic structure of the element that you want to create, present your model to the chemical

engineers.”

Students will use their textbooks or Ipads to research the structure of their atom.

They will then build a model of their atom. Students could mount their model onto a piece of

paper, where they could include the legend and information about each part of their atom.

This model will form part of their final showcase. Students may use household materials or

purchase materials for their model. If you have students working in groups of 4, it is advised to

get your students to produce 2 atoms; they should then choose the best one for their final

showcase.

At the end of the activity, you can show their work in a gallery walk around the classroom or in

the hallway. Students could use the rubric to grade each other’s work using Post-it notes.

Science and Engineering Practices in the NGSS

1. Asking questions (for science) and defining problems (for engineering)

2. Developing and using models 3. Planning and carrying out investigations 4. Analyzing and interpreting data 5. Using mathematics and computational

thinking 6. Constructing explanations (for science)

and designing solutions (for engineering) 7. Engaging in argument from evidence 8. Obtaining, evaluating, and

communicating information

Crosscutting Concepts in the NGSS

• Patterns: observed patterns in nature guide organization and classification and prompt questions about relationships and causes underlying them.

• Cause and Effect: Mechanism and Prediction: Events have causes, sometimes simple, sometimes multifaceted. Deciphering causal relationships, and the mechanisms by which they are mediated, is a major activity of science and engineering

• Scale, Proportion, and Quantity: In considering phenomena, it is critical to recognize what is relevant at different size, time and energy scales, and to recognize proportional relationships between different quantities as scales change.

• Systems and System Models: A system is an organized group of related objects or components; models can be used for understanding and predicting the behavior of systems.

• Energy and Matter: Flows, Cycles, and Conservation: Tracking energy and matter flows, into, out of, and within systems helps one understand their system’s behavior.

• Structure and Function: The way an object is shaped or structured determines many of its properties and functions.

• Stability and Change: For both designed and natural systems, conditions that affect stability and factors that control rates of change are critical elements to consider and understand.
