This lab activity has learners create a pendulum with a one-second period.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

Learners build simple catapults and use them to launch cotton balls.

In this activity, which requires adult supervision, learners get to explore the awesome power of chemistry.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

Get all wrapped up in a lesson about skin!

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).
