Astronomy for Every Kid

"Astronomy for Every Kid: 101 Easy Experiments that Really Work" by Janice VanCleave

Janice VanCleave is a former science teacher and author of dozens of science experiment books for young children. You can go in order or pick and choose which experiments you want to do. These books are a great resource for your children during the summer months if you want them to do something educational but also fun and exciting. Generally speaking, you do not have to an abundance of supplies for the experiments. Many of them use everyday objects and many times, those objects are repeated in other experiments. Clay and masking tape are some examples of things used repeatedly.

Here is an example "#64 Daytime Stars"

"Purpose: To demonstrate that the stars are always shinging."

"Materials: paper hole punch, index card, 1 white letter envelope, flashlight"

"Procedure:
Cut 7 to 8 holes in the index card with the hole punch.
Insert the index card in the envelope.
In a well-lighted room, hold the envelope in front of you with the flashlight about 2 in from teh front of the envelope and over the index card.
Move the flashlight behind the envelope,
Hold the flashlight about 2 in. from the back of the envelope."

"Results: The holes in the index card are not seen when the light shines on the front side of the envelope, but are easily seen when the light comes from behind the envelope and toward you."

"Why? Light form the room passes through the holes in the card regardless of the position of the flashlight, but only when the surrounding area is darker than the light coming through the holes can they be seen. This is also true of stars. They shine during the daylight hours, but the sky is so bright from the Sun's light that the starlight just blends in. Stars are most visible on a moonless night in areas away from city lights."

You can buy these experiment books cheap on Amazon.
