Measuring the Earth

We moved on to Geology. Elijah is in heaven because it is rocks and minerals and all that "stuff" he loves so.

He used an apple to measure a sphere.

He measured the center of the apple with a string and found it was 10 inches.



Then he cut the apple through its equator and measured again with string for 3 inches.




We learned that the earth would need a string that was 25,000 miles long for the equator to be measured and it gave us a good idea what the earth would be if we cut it in half for the diameter. This experiment made a nice snack. :)

This was such a cool experiment and a yummy snack. I love green apples the best.
