Scientific Method

Does the volume of water change when it freezes?

Snails move faster on glass than on concrete 

If snails move faster on smooth surfaces, then a snail will move faster on glass than concrete

What makes the pupil in the eye change size?

Container 1 - Water: 14.0 ml, ice: 14.8 ml  / Container 2 - Water: 20.0 ml, ice: 20.8 ml 

I will compare the volume of a glass of water at room temperature with a glass of frozen water

I will test my partner's pupils by covering one eye and shining a light directly into the other

After consistent results, I found that the water increases in volume when it freezes.

The results showed green light was the least effective color for growing plants

I will organize snail races on glass and concrete and compare how fast snails travel on each

I will place 4 plants under green lights and 4 under red lights and compare their growth  

Do snails crawl faster on concrete or glass?

If plants reflect green light, then they will absorb red light and grow faster under red light

If solids are more dense than liquids, then water will decrease in volume when it freezes. 

Which color lights cause plants to grow more effectively?
