Layers of Planet Earth

Teaching Tip: Layers of Planet Earth
By: Sarah M., Grade 7 & 8 Science Teacher

To teach a child the layers of Earth is a difficult task, he/she can not imagine what we are describing. So I took an apple and cut it in half. Wow! Every part we want to describe is in that apple. Starting from the core moving upward to the apples skin which, represents the Earth´s crust. It even led them to draw the layers. They are reminded of the Earth's layers each time they have an apple. Try it! It works!
