80-b here again coming to u with the heat and matter. HEAT: when i learned about heat I found out that it can be dangerous  but fun at the same time there is one cool thing with heat.    Take 4 Styrofoam cups 1 color of food coloring (any color) take a plastic tray ( small and it not like a can) and hot water, and see how u can do this experiment.

                MATTER: Matter is something that helps something fall and dp this experiment: take 2 pieces of paper and crumple 1 up and then drop them and see which one goes down 1ST
