This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.
