Exploration
![Page 3: Mark Schemes Practice Exploration (formerly Design) Honors Physical Science](https://reader035.vdocuments.mx/reader035/viewer/2022062322/5697bfa91a28abf838c99b3f/html5/thumbnails/3.jpg)
Exploration includes…• 1. An introduction to your investigation.• 2. Materials/Method portion of your investigation• Possible section headings in Exploration include:– Variables– Materials– Diagram of experiment– Method– Safety
![Page 4: Mark Schemes Practice Exploration (formerly Design) Honors Physical Science](https://reader035.vdocuments.mx/reader035/viewer/2022062322/5697bfa91a28abf838c99b3f/html5/thumbnails/4.jpg)
1. Introduction• To write your introduction, you must first do these
things:• A. Define the problem– EX: Question – How does the chew time affect the bubble
size?
• B. Select variables– EX: IV - type of bubble gum, DV – bubble size, CV - time
chewing, person blowing bubble, method of measuring, etc.
• C. Conduct background research on topic• D. Personal significance statement**

Helpful Hints: Introduction• This section tells the reader why you did the experiment.
Include background information that suggest why the topic is of interest and related findings. It should contain the following:– Descriptions of the nature of the problem and summaries of
relevant research to provide context and key terms so your reader can understand the experiment.
– A statement of the purpose, scope, and general method of investigation in your study. Express the central question you are asking.
– Descriptions of your experiement, hypothesis(es), research questions. Explain what you are proposing for certain obervations.

2: Materials/Methods
• Include list of materials• Sometimes a photograph is helpful• List steps of method/procedure• Plan should have a trial run and repeats until
consistent results are obtained (3 trials)• Be clear and concise, making sure someone
could repeat it• Include diagrams of set up as needed
![Page 7: Mark Schemes Practice Exploration (formerly Design) Honors Physical Science](https://reader035.vdocuments.mx/reader035/viewer/2022062322/5697bfa91a28abf838c99b3f/html5/thumbnails/7.jpg)
Helpful Hints: Materials/Methods• This section should describe all experimental procedures
in enough detail so that someone else could repeat the experiment. Some guidelines to follow:
• Explain the general type of scientific procedure you used to study the problem.
• Describe what materials, subjects, and equipment you used (Materials).
• Explain the steps you took in your experiment and how did you proceed (Methods).
• Mathematical equations and statistical tests should be described.

Prompt• Investigate some physical property of a bouncy
ball.1. Create your own exploration.2. Analyze your explorationusing rubricand checklist
• 3. Analyze your partner’sexploration4. Reflect on the process, strengths and weaknesses

1. Create your exploration• Research Question / Identify variables– Independent– Dependent– Controlled
• Control Variables– Manipulate independent variable– Attempt to maintain the controlled variables
• Method for collection of data– Collect sufficient amount of data– Trial run and repeats until consistent results are
obtained

2. Analyze YOUR Exploration by using the checklist
• Take 5 minutes or so and read over your Exploration.
• Make sure you have included all the listed requirements.
• Assess your aspects using the checklist and the rubric.
• “What grade would I earn?”

3. Analyze Partner’s Exploration
• Trade with the partner (See Board)• Analyze using the checklist and rubric.• Assign a grade at the top of the paper– Write the number, 1-6– Justify using the checklist

4. Reflection Time!
• Trade with partner to get YOUR Exploration back• Look at feedback – agree or disagree? No hard
feelings, we’re all new at this : )• Reflection free write:– 1. Which part was my strength? Why?– 2. Which part was my weakness? Why?– 3. How can I improve my current Exploration?– 4. What will I do differently when I create my next
Exploration?• Hand in your Exploration and Reflection and…
