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.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this physics activity, learners will explore buoyancy.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.
