Wiley's+Redesign

The experiment I'm going to to redesign is my marble maze from fourth grade. The materials that are readily available are clay, tape, paper, craft sticks, straws and cardboard(for the base). It acts like its going to fall because it's higher areas are to heavy. supports aren't strong enough. I can change the weight, the number of supports, size of the marble, incline of the maze and the height of the starting place and the length of the course. I can measure the response to the changes because it might not be leaning over anymore.

I would like to see what happens when you mix toothpaste with medicine and chemicals and stuff. the materials that are readily available are toothpaste, medicine, chemicals and liquid hair stuff and paint. It changes colors when its chemicals and paint. it smells when its hair stuff and medicine. I can change what goes with what or how or much of it I use or what type of container the stuff is in. I can measure the response because of how much it changes.
