6: Working Out the Core
from Bedrock: Earth's Earliest History
Today, we'll learn how deep humans have traveled into the planet, and how we know what's even deeper down. We'll meet mineral oozes, coils of liquid iron, and a Danish woman from the 1930s who discovered the center of the Earth. Extra credit: Make a tin-can telephone, find an inductor in one of your electric appliances, or look for an aurora.
