Activity

Models of the Earth

In this activity, students use models to visualise the layers inside the Earth.

The models use food items to demonstrate the layers. As an alternative to food, consider using plasticine or playdough to create the models.

Edible model of the Earth

Create an edible representation of the Earth's layers using a small hard candy as the core, a marshmallow for the 'squishy' mantle and chocolate for the crust.

By the end of this activity, students should be able to:

  • identify some of the layers inside the Earth

  • describe some of the physical characteristics of these layers

  • explain how the models are a representation of the Earth

  • discuss how these models are different from what is really inside the Earth.

Nature of science

Scientists often use models to explain things we cannot easily see. The models used in this activity help students picture some of the characteristics of the layers inside the Earth.

Activity idea

In the Tectonic sandwiches activity students make sandwiches to investigate tectonic plate boundaries and how they move during an earthquake.

Tectonic jigsaw puzzles helps students to visualise what is happening below their feet.
