WHAT IS SCIENCE?
Mini Project:Question: What is Science?
Objective: To create a interpretation of what you think science is.
Materials: 8.5 x 11 Sheet of paper (computer paper), pictures (clip art, Google images, draw), words or you may use GlogsterEDU to create your project. To use GlogsterEDU see Mrs. Vidito’s links page for directions. GlogsterEDU
Procedure: 1. Create a mini-poster to answer the question: What is Science?2. Poster needs to include ONLY 5 – 10 pictures and ONLY
5-10 wordsa Need to include the skills of a scientist, branches of science and how scientist solve questions.b. Needs to be neat and organizedc. Name, date and class color in upper right hand
corner

WHAT SKILLS DID YOU NEED TO SOLVE THESE PROBLEMS?
LAB 1A: MISSION POSSIBLE LAB 1B: MYSTERY CUBE
A. Observing: using the five senses to gather information about the world
B. Inferring: making a conclusion based on your observations
C. Predicting: using past experience or current evidence to make an inference about the future
D. Classifying: grouping together similar itemsE. Making Models: helps us to understand things we
cannot seeF. Communicating: the process of sharing ideas
and information

Inquiry Process

What do all these processes share and how are they different?
![Page 13: InferenceEvidenceExplanation HW: 3 Column Notes – Lab 1b: Mystery Cube](https://reader036.vdocuments.mx/reader036/viewer/2022062620/551aba26550346856e8b53b6/html5/thumbnails/13.jpg)
THE EXPERIMENT OR THE INVESTIGATION
WHAT DOES A GOOD EXPERIMENT CONTAIN?
•Testable hypothesis•Identify and limiting the variables•Ensuring constants within the experiment •Qualitative data – descriptive data•Quantitative data – numeric values•Using Models•Having multiple trials•Designing data tables to organize information•Eliminating bias: (to have a preference - opinion)•Using standardized units of measure•Being safe•Finding materials
![Page 14: InferenceEvidenceExplanation HW: 3 Column Notes – Lab 1b: Mystery Cube](https://reader036.vdocuments.mx/reader036/viewer/2022062620/551aba26550346856e8b53b6/html5/thumbnails/14.jpg)
Hypothesis: an educated guess that can be tested An if…then statement Will either be supported or not supported – never
right or wrong!
Shows a relationship between the independent and dependent variable.
A FEW MORE DETAILS… THE HYPOTHESIS
If a plant is talked to then the plant will grow bigger.
![Page 15: InferenceEvidenceExplanation HW: 3 Column Notes – Lab 1b: Mystery Cube](https://reader036.vdocuments.mx/reader036/viewer/2022062620/551aba26550346856e8b53b6/html5/thumbnails/15.jpg)
Variables: Independent Variable: is the variable changed
by the scientist There is always only ONE! Also known as the manipulated variable
Dependent Variable: is a measure of how the independent variable responds
Also know as the responding variable Quantifiable value (a number usually)
TESTING THE HYPOTHESIS
Measure the growth of each
plant
Talking to plants: plant A – 1minPlant B – 2 minPlant C – 3 minPlant D – 0 min
![Page 16: InferenceEvidenceExplanation HW: 3 Column Notes – Lab 1b: Mystery Cube](https://reader036.vdocuments.mx/reader036/viewer/2022062620/551aba26550346856e8b53b6/html5/thumbnails/16.jpg)
Control: within an experiment one setup will not have the independent variable applied.
This setup is used measure if the independent variable is causing change. NOT EVERY EXPERIMENT HAS A CONTROL.
Constants: quantities that will remain constant within an experiment

Question Independent Variable(What I changed)
Dependent Variable( What I observed or
measured)
Controlled Variables(What I keep the
same)
How much water flows through a faucet at different openings?
Does heating a cup of water allow it to dissolve more sugar?
Does fertilizer make a plant grow bigger?
Do different brands of candles burn faster?

Who listens to the most music: teenagers or parents?
Is the classroom noisier when the teacher leaves the room?
Do bicycle fenders keep the rider dry when riding through a puddle?
