states of matter

Light a Bulb with a Balloon

We are used to thinking that it takes a lot of energy to produce light. This time, we will see that even a small amount of the right kind of energy can give us some light.

This experiment will not work with the incandescent bulbs commonly used in lamps. They have a thin wire, called a filament, which has to get hot enough to glow to give you some light. That takes quite a bit of energy, and much of it is lost as heat.

A Watched Pot

This experiment came from researching an experiment on cooked vegetables. As I was boiling each vegetable sample, I had quite a bit of time to watch the water boil. If you have ever watched a pot of water boil, did you notice all the strange things the bubbles did? No? Then it is time to go back to the stove and boil some water.

States of Matter

I collect books of science experiments, and it amazes me how many still teach the three states of matter. I thought that this time, we would look at the FOUR states of matter. (Actually, there are more states of matter, but these four are the common ones.)

Ice and String

Imagine that you are given a glass of water with a couple of ice cubes floating in it. You are given a string and told to pick up the ice cube with the string, without touching the glass, the ice, or the water with your fingers. Could you do it? Of course you could, if you knew the science.
