In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

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

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

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

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this activity, learners explore the engineering behind the conveyor belt and consider the impact this invention has had on transportation and the coordinated shipping and delivery of goods.
