Jordan is doing a science fair project on the effects of music on the growth of tomatoes yes to tomato plants plan a.m. Plan B t
hey close in a window and gives each of them water that a is exposed to classical music is on headphones attached to the soil plan B is not exposed to any music throughout the growth period Jordan counts the number of tomatoes produced by each plant. What is the independent (manipulated) variable?
The independent variable is the variable in an experiment that is changed to determine if the change will have an effect on the subject. With the title alone, "The effects of music on the growth of tomatoes", we can see tht Jordan wants to see the <u>effect of music. </u>To test this, music is changed to determine if there is any difference.
On one plant classical music is played and on the other, no music is played. So what was changed is the music or exposure to music.
