In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

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

In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.

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

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

In this activity, learners explore Charles' Law in a syringe.

In this activity, learners slide shapes to create unusual tiled patterns.

This is a lesson plan for an activity in which learners, playing the role of archeologists, use math concepts about number bases to decipher the Dresden Codex, an ancient Mayan document.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.
