Demonstration

Help your students learn more about how we study the Earth's interior without being able to take a field trip. It starts with Seismic Slinkie activities that show how waves travel differently in "different mediums." Then it ties into an interactive poster of the Earth layers, and can continue onto an online investigation into "Determining and Measuring Earth's Layered Interior".

Together, these activities build critical thinking, data analysis, and collaboration skills while connecting evidence gathering and seismology into a memorable, classroom experience.
