Maracas. For home made maracas, all you need are paper plates, dried beans and tape. Give each child two paper plates. Have them color and decorate the bottom of the plates any way they wish. Fill one plate with about cup of dried beans, place the other plate on top, face down and tape together - making sure you seal all the way around. The hollow area creates the space for the beans to shake around and make noise!
The first thing to point out is that the wind changes everywhere you go. Even if you think the wind is consistent from place to place you will soon find out by taking a little data that changes all during the day and from week to week. As a matter fact, one area on your property around your house will be very different than another area. One might be excellent for installing wind turbines in the next might be terrible. Explain to your children that you need to take some data with an anemometer. An anemometer is just a little device that will allow you to simulate the way of wind turbine would work on your property. You can put up to various places and collect data over span of a few months and then analyze what you learned and compare locations that way.
If you add something for the crystals to cling to, like a rock or a stick, crystals can now grow. If you "seed" the object (coat it with the stuff you formed the solution with, like salt or sugar), they will start forming faster.
