| These are some of our older experiments. In the first four pictures, from last October, we poured acetone on the front desk, lit it on fire, determined how long it took to burn, and determine how long it would take to burn a 2-liter bottle of acetone from those measurements. Somehow, I think we determined it would take a couple hours for the thing to burn. In the bottom three pictures, we determined what kind of compounds when dissolved in water would conduct electricity. Ionic compounds work, but covalent compounds don't. The blue liquid is copper-something in an ionic compound, and the clear one I think was salt water. |
