Why is it important to have only one independent variable and to control the other variables when performing science experiments?

• So you can tell which factor is causing the change in the experiment and get more accurate results

• It does not matter, you can have as many independent variables as you want.

• None of these answers are correct

Ben makes five paper helicopters with different wing lengths. He drops them the same way from a height of two meters for five trials each. He records the amount of time it takes for each helicopter to fall to the ground.

What is the independent variable?

• Dropping the same way

• Wing Length

• Amount of time it takes the helicopter to hit the floor

• Dropping from the same height

Cindy wanted to find out how the amount of sunlight affects the growth of plants. She placed two tomato plants in 10 inch pots with potting soil and watered them ¼ cup each day. One plant was placed under a cardboard box and one was placed in the sunlight. She measured the growth of the plant each week for three weeks. What is the independent variable?

• Using the same type of plant

• Each plant was placed in a 10 inch pot

• The growth of the plant

• One plant is in the sunlight and the other is under a box
