Question

Jordan is doing a science fair project on the effect of music on the growth of tomatoes. He has two tomatoe plants,plant A and plant B, that he grows in a window and gives that same amount of water.plant A is exposed to classical music using headphones attached to the soil. Throughout the growth period, Jordan counts the number of tomatoes produced by each plant.
What is the control group?
What is the independent variable?
What is the dependent variable?
What should jordan's conclusion be?
Jordan need to repeat this experiment, what should he do differently?

Answer 1

The control group is the type of tomato the plants are.
The independent variable is the type of music played.
The dependent variable is Plant A and B's growth.
His conclusion should be that music does not affect the growth of tomatoes.
He should make sure both plants were getting the same amount of water, soil, light, seed, and fertilizer so that can't affect the tomatoes in any way.
