In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

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.

In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.
