In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.

Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.
