Science Buddies: "Ask an Expert"

My grandson is also doing his science fair project on vermicoposting we are having trouble with the Variables: It is his first time any ideas?

Hi,

The main Science Buddies site has a great resource on variables for beginners, here: https://www.sciencebuddies.org/science- ... test.shtml . Take a look at that, and if you still have questions after you have read it, please post back.

Good luck!

The link posted above contains a great explanation for how to come up with your own variables. An example of something you could do would be along the lines of using two different types of worms (independent variables) and seeing how much compost they create in a give amount of time (dependent variable). I hope this helps you come up with ideas on your own!
