Why is using only one trial to collect data in an experiment NOT a good idea?

• Increases the likelihood of accurate results

• Increases the likelihood of inaccurate or unreliable results

Identify the control variable in the following experiment: A researcher wants to test how different brands of paper towels absorb water, so she uses the same amount of water for each brand of paper towel.

• Brand of paper towels

• Amount of water

• Time taken for the water to be absorbed

• Type of water used

What is the independent variable in the following experiment: A scientist wants to see how the color of light affects the growth of algae, so she shines red light on one group of algae and blue light on another group.

• Type of algae

• Amount of water given to each group

• Temperature of the room

• Color of light
