The Earth's Interior

We can't dig a hole through the Earth, so how do we know about the layers beneath our feet? Scholars learn about layering through hands-on exploration of common materials. They study the characteristics of each layer and apply their...

For this Earth's interior worksheet, students read about the geology of the Earth, the layers of the Earth's crust and the forces that change the Earth's surface. Students label the Earth's layers on a diagram, they answer 2 questions...

All of the gas giant's atmospheres consist of hydrogen and helium, the same gases that make up all stars. The third in a series of 22, the activity challenges pupils to make scale models of the interiors of planets in order to...

Geology rocks — literally! A geology chapter offers eleven activities at four different levels. Scholars enjoy completing hands-on experiments before applying critical thinking skills following a share, process, generalize, apply,...

The big question is, how do we know about the composition of the earth's core? Sal explains that at 105 degrees from the source point of an earthquake, the phenomenon of the p wave shadow zone leads us to conclude that the waves are...

Young scholars introduced to the interior structure of the Earth. They explore how the Earth's interior is broken down according to both it's physical properties and it's chemical composition. Students explore how convection currents...

Visit an active volcano site to find out the connection between the movement of the Earth's plates and the processes deep within the Earth's interior. [58:23]

Stunning images make up this slide show on the inner planets of our solar system. While visiting Mercury, Venus, Earth, and Mars, viewers also are introduced to the International Space Station and the Spirit Rover on Mars. Follow this...

Seven hands-on lessons module where students learn about our dynamic planet. These inquiry-based explorations investigate scientific models, earthquakes and seismic waves, Earth's interior, Earth movements, the lithosphere, plate...

Young scholars will examine the layers of the Earth. In this geology lesson, students create a scale model of the Earth's interior using cash register tape. They will determine the percentage of error in the scale compared to the actual...
