Why is it important to collect data?

• because
• it gives you busy work
• They are magically delicious
• in order to share your results with others

This variable in an experiment is the one being changed by the scientist. 

• dependent variable
• independent variable
• data
• control group

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...

• The type of plant
• The amount of sunlight
• The type of music
• The type of liquid

Dependent variable means

• the scientist controls what to test
• educated guess
• ask a question
• what is being measured

Identify the independent variable: 
Every time a bear farts in the woods, James Cameron earns $3 

• $3 for Jame Cameron

Identify the problem with this experiment:  
A scientist thinks that flatworms swim faster if they are in salt water.  So he drops them in salt water and finds that they do swim very fast.  He concludes that salt water makes flatworms swim fast.  

• No independent variable
• Too many independent variables
• No control group
• No experimental group

Safety goggles should only be used when working with

• an open flame

• chemicals

• using a mechanical device

• all the answers are correct
