Question

then give 2 examples. for question. 1 and 2

thank you in advance for those who answered it correctly

Answer 1

controlled variables are the ones who remain constant in an experiment

experimental variable is the one manipulated in an experiment

example.

you want to know the effect of water in the growth of plants. You use 2 set-ups. all variables should be constant except water.

Set-Up A: with sunlight, air and water

Set-Up B: with sunlight, air but no water

in this case sunlight and air are the controlled variables, while water is the experimental variable.
