Making an ant farm with your children is fun and a good educational tool as well. It can teach children the importance of an eco system. Ants are a good pet for apartments or a home with limited space. They are perfect for families with allergies. And best of all, ants don't cost much to feed.
Fossils offer us clues about life in the past -- even years and years ago! Normally when a plant or animal dies, its remains either decay or perhaps are consumed by another animal. Sometimes though before that happens the conditions can be just right and the remains become buried and preserved.

Several people wanted to know why this earthquake produced a tsunami when most earthquakes do not. To understand that, we need to know about faults. Before you start listing all my faults, such as forgetting to include parts of the experiment, I am talking about geologic faults.
Anytime there is an earthquake, the news media makes a big point of talking about the Richter Scale, using it to indicate how bad the earthquake was. As we will see, the Richter Scale does not tell us nearly as much about surface effects as people think it does.
What happens? Is more than one color appearing as the water spreads? Try another color. Is it a single color or a mix of colors? Do some of the different pigments travel faster and farther than others? Make a pictograph, (a picture display), showing which pigments were used to make each marker.
What does a seed need to grow? Let's set up an experiment with radishes and find out! Radishes must be one of the easiest things to grow on the planet. Even a non-"green" thumb can't mess this up!
Try out nature's very own dyes! Did you know that a great source for natural dyes can be found right outside your door? Roots, nuts and flowers are just a few common natural ways to make many colors. Yellow, orange, blue, red, green and brown are readily available
Today's experiment will help you see and taste that small, water-soluble molecules -- like color pigments and sugar -- are transported by water through xylem stem to the leaves and flowers of a plant.
