In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

In this activity, learners play NOAA's Carbon Tracker game and discover ways to keep track of carbon dioxide and other greenhouse gases in the world.

In this activity (11th activity on the page), learners use pennies to test their hearing acuity.

This game explores the different reasons we choose to eat, and helps us be aware of when our body needs food and when it does not.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

In this math activity, learners play a game and identify patterns with fun moves and sounds. Discover how dancing and signing involve patterns.

In this health activity, learners create a device so that they not only feel their heartbeat, but also see it, using a straw and some clay.

Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.

In this activity, learners practice matching and subitizing as they create the longest domino train possible.

In this activity, learners investigate static electricity using everyday objects at four different stations.

Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this activity, learners explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.

In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.

In this activity (pages 8-9), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

In this activity, learners will explore saturated solutions and discover how crystals form.

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.
