Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this activity, learners build a carousel toy that spins when pushed down.

In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

This outdoor activity/field trip requires a place where minnows swim, such as a local pond or brook.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In this "Sid the Science Kid" activity from Episode 109: The Perfect Pancake, learners make applesauce to explore irreversible change.

In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).
