Scientific Method

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

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

Which of these is a testable question?

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

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

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

Ms. Taylor reads book and magazines on cooking. Which step of the scientific method is she on?

Jimmy Johnson wants to know if putting bigger tires on his race car will make him go faster.

Does the volume of water change when it freezes?

Do snails crawl faster on concrete or glass?

Ms. Walters records how her students did on their math class in her data tracker.

Snails move faster on glass than on concrete 

Which color lights cause plants to grow more effectively?

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

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

Before an experiment you need to collect your materials and write down what you need to do

My hypothesis was wrong. M&M's don't complete dissolve in water.

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?

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

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