Answer 1

Is black marker ink made of the same colors in different brands of markers?

Put a spot of black marker ink about 1 cm away from the lower edge of a strip of paper cut from a coffee filter. Hold the lower edge in a container of water, just barely letting the edge touch the water. Before long the ink will travel up the filter paper with the water. Any colors will separate from each other. If the water goes up the coffee filter, but the ink does not move, try a different marker. When the water is nearly to the top of the paper strip, remove the paper strip from the water and let it dry. Repeat with different brands. Compare the paper strips.

You could do the same method with different colors of markers: find out if any of the same colors of inks are blended into red markers, green markers, black markers, ....

This method is called paper chromatography. You can find plenty of information for your report on the Internet.

Here are a few ideas from "the barrel":

1. Get moss, mix thoroughly in milk (don't drink it), poor onto an object with an interesting shape (maybe something you could carve out of wood). Most likely, moss will grow in as little as one night. Just keep it out of the Sun. If you keep it in a bathroom, the moisture in the air will help it grow very well. And it looks cool.

2. Go out near a stream and look for geodes. A geode is a natural mineral deposit inside a rock. Usually geodes take millions of years to create, but only a few hours to find. Cut it in half, and polish it somehow (when in doubt, concrete will work to "sand' it).

3. Go to a building supply place like Home Depot and buy a 2x4, at least 8 feet long. dip a hole at least a foot deep, half fill it with rocks then stick the 2x4 in there and fill it in until you couldn't easily wrestle it out of there. Then carefully pick a spot near the base, mark it, and take ten pictures of the 2x4, each 20 minutes apart, every day for two weeks. The resulting "flipbook" will no doubt feature the thing seeming to dance. It does this because moisture causes warping in the wood, but it never stops, it just changes.

4. Get a small vise, and attach it to an aparatus that will hold it up. Then, get a turkey wishbone, and suspend it from the vise by one side, so that the other is parallel to the table. Then get some tiny weights (the kind they use on an old-fashioned scale), and see how much weight it takes to snap the wishbone. Record your observations, find out where the wishbone is located, and find out how the turkey uses this piece of its body.

I bet your science teacher will be impressed by any one of those. And if not, you didn't get 'em from me.

Answer 4

Does the full moon change size over the course of the night (from horizen to overhead)? You can do measurements, and it's a cool optical illusion. You can find info on it at www.badastronomy.com and www.wikipedia.org.

Answer 5

Go get several small plants (all the same kind) and set them up in small boxes under the big kind of Christmas tree bulbs (one plant under each bulb, separated from each other). Your experiment can determine which color of light helps plants grow best.
