independent variable is what is being changed- so the amount of water and the light, what type of music, string or rubber band
dependent variable is what is changing is response to the independent variable, so the plant growth, time it takes for baby to quiet, etc.
put hypothesis in “if..then..” statement by putting the independent variable and then the dependent variable in the blanks.
for example, “if the amount of water is increased, then the plant growth will increase”
“if classical music is played, then the baby will quiet faster”
hope that helps
