So, your project is simple. Each and every one of you are going to figure out, how the number of seeds placed in a container affect the height of a plant. You will need 4 containers. In the first container you would have 5 seeds in the next you would have 15 next 20 then 30. What are some control variables in this experiment?

I do! A dependent variable is the factor that we observe or measure in an experiment, an independent variable is one thing we change during an experiment and a control veritable is all the things we keep the same during an experiment!
oooh
A couple control variables in this experiment are, the type of seed used, the time you wait to measure the plants, the space where you store the plant and the size and thickness of the container.
