Miss Glidden conducts an experiment to find out if soda or water makes plants grow faster. In this scenario the soda/water is the _______ variable.
What is the independent variable?
The least dense substance listed:
- water 1.0 g/mL
- oil 0.9 g/mL
- Copper 9.8 g/mL
What is oil?
This property of matter changes depending on the state of matter a substance is in. (Why does ice float?)
What is density?

Claim: Coffee disrupts sleep cycles.
Evidence: When a group of people drink coffee and go in for a sleep study they have less REM sleep than a group that doesn't drink coffee.
Reasoning:__________________
Because people who drank coffee before a sleep study had less REM sleep than those that did not drink coffee it can be concluded that coffee disrupts sleep cycles.
