River Catcher
Source Institutions
In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

Exploring With Sound
Source Institutions
In this activity, learners use sound to figure out, or infer, the position of objects. Learners create a maze inside a shoebox with blocks of wood.

Caller ID: The Frog - and Toad! - Mating Game
Source Institutions
This activity is a sensory experience that recreates the sounds of a pond at night.

Ice Cube Painting
Source Institutions
In this activity, learners "draw" with frozen tempera paint. The ice cubes are prepared the day before by placing watered down tempera paint and popsicle sticks in ice cube trays.

Thermal Energy Put to Work
Source Institutions
In this activity, learners determine whether thermal energy can be used for work.

Corals and Chemistry
Source Institutions
In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

Rocket Pinwheel
Source Institutions
In this activity, learners use simple materials to construct a balloon-powered pinwheel. The pinwheel is a great way to investigate Newton's Third Law of Motion.

Weather Stations: Phase Change
Source Institutions
In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

Let's Dew It!
Source Institutions
From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

Trash Traits
Source Institutions
In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

Magnet Races
Source Institutions
In this physics activity (page 4 of the PDF), learners will explore how similar magnetic poles repel one another. They will rely on linear induction to race magnets around a simple course.

Toasty Wind
Source Institutions
In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

Build a Rocket - and a Launch Pad!
Source Institutions
In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

Under Pressure
Source Institutions
In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

Construction Technologies: Construct the Strongest Bridge
Source Institutions
Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

Air, It's Really There
Source Institutions
This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

Over the Hill
Source Institutions
In this physics activity, learners construct a small-scale version of a classic carnival game.

Changing Colors
Source Institutions
Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
