What’s inside the earth?
September 13th, 2007
Well –that’s what the L’s asked me last weekend so I decided to ask them right back. Loghlen answered ‘gravity’ which I thought was pretty cool. Lukie said it’s very very hot in there and Leah said ‘apple’. Apple! –what a great idea to help us talk more about our planet. So:
1. Mommy, Lukie and Leah cut an apple in half.
2. Then Loghlen measured the diameter of the apple. It was 2.5 inches. This is just like the equator –an imaginary line running through the center of the earth equidistant from the North Pole and South Pole. It divides the Earth into a top half and a bottom half known as the Northern Hemisphere and Southern Hemisphere.
3. Then we all colored the core of the apple. Just like the apple our earth has a core too. In fact the earth has an outer core and an inner core. The core measured about 3/4 inch at it’s widest. Look at the great coloring job we did as well.
4. Next we measured the apple’s flesh –the distance from the outer core to the skin of the apple. This is just like the earth’s mantle. We measured about 5/8 inch.
5. Finally we measured the skin of the apple as accurately was we could (it was about one tenth of an inch). This is just like the earth’s crust.
When we finished the 3 L’s all colored the Science With Me! What’s inside the Earth? coloring sheet. You can find it here if you’d like to have your kids do it: http://www.sciencewithme.com/worksheets.php?cid=10
See Loghlen’s above. He did a nice job–especially those lovely blue oceans.
Enjoy!

Deifnetely a great idea for the kids to literally get their hands on it! Even when I was kid I was always wanting to learn by creating it, holding it, so to actually be able to see the world like that truly gave the kids a full understanding. This site is great and I will be visiting a lot more often! Especially now that it’s summer, kids are just sitting around home and it is the perfect time to have some cool science experiments at home. Anymore cool science activity ideas for home??? It’s the perfect way to keep the kids busy while they also learn something. Thanks!
