Here are some ideas that are fast, easy, fun - and educational:
1. Explore the cell membrane by soaking an egg in vinegar so the shell comes off, then soaking in water and then in dark syrup.
2. Dig up a couple of cups of dirt from your backyard, add water and put them in a large clear jar. Shake vigorously, and watch it settle into the soil layers. You can put this into a soil triangle for more fun.
3. Find out if the shape of a piece of ice affects its melting time. Take the same amount of water, put into different shaped containers and freeze. Calculate the surface area of the ice, then time how long the pieces take to melt.
