something the scientist changes on purpose
200
What is the correct format of a chemical symbol on the periodic table?
First letter capital, second letter lowercase
200
How is a wavelength measured?
Crest to crest OR compression to compression
200
What does a load do in a circuit?
turns electricity into another form of energy
200
What does Newton's 3rd law of motion say?

- more: batteries, wire wraps
- bigger: batteries, core, wire
300
How is speed calculated?
Speed = distance/time
400
What is a control?

How does adding heat affect matter?
Causes it to:
- spread out
- move faster
- change phase

What is the difference between reflection and transmission of light energy?
reflection bounces it back and transmission lets it pass through
400
What is the difference between a series and a parallel circuit?
series only has 1 pathway for the energy and parallel has multiple pathways
