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 chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this activity, learners design a device to solve a problem: how to get a ball out of a drain pipe.

In this chemistry activity (page 8 of the PDF), learners will identify the instances of physical change, chemical change, and solutions while making homemade soda pop.

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

Using household materials, learners can make white gooey globs from clear solutions. Alum, dissolved in water, reacts with the hydroxide in ammonia to create aluminum hydroxide.

In this physics activity, learners will explore buoyancy.

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 activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?

In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.

This is written as a display, but can easily be adapted to a hands-on activity. Learners discover how all the parts of a diaper work together to keep babies dry and comfortable.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.

In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.

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

In this quick activity, learners observe how wind creates ocean currents.
