Earth Science for Every Kid

Janice VanCleave's Earth Science for Every Kid: 101 Easy Experiments that Really Work

If you have never heard of Janice VanCleave, she is a former science teacher and author of dozens of experiment books for young children. The experiments range in complexity as well as age.

I specifically think her experiment books are good for homeschooling families or families looking for
something to do during the summer months because you can easily pick and choose an experiment. You can choose to do some of the more simpler experiments for younger children, and then you can save the book for the following year or year after even.

Here is one example "#23 Shifting"

"Purpose: To demonstrate continental separation"
"Materials: cookie sheet, 2 cups dirt, 1 qt bowl and a spoon"

"Procedure:
Pour the dirt into the bowl
Add water and stir with a spoon until you have a thick mud.
Pour the mud into the cookie sheet
Set the pan of mud in the sun for 2-3 days.
Push down around the sides of the dried mud."

"Results: The surface of the dried mud cake cracks."

"Why? The mud is broken into pieces with jagged edges and all the pieces fit together. The continents of the earth, like the mud cake, look like large jigsaw-puzzle pieces. The coastlines of the continents have irregular shapes that appear to fit together. In the past, pressures within the earth may have broken a large land mass into the pieces that now form the separate continents on the earth."

Some of the other Earth Science topics covered in this book are:

Earth in Space
Rocks and Minerals
Erosion
Atmosphere
Weather
Oceans

You can typically find these books for a very cheap price, especially used, on Amazon.
