In this activity (on page 2), learners create a submarine using a plastic cup. This is a fun way to learn about buoyancy and density.

In this outdoor activity, learners discover the wonders of the habitat surrounding them.

In this engineering activity, challenge learners to invent a water filter that cleans dirty water.

In this sensory activity, learners enjoy the fun of a snow day any season of the year.

In this outdoor activity linking human health to the environment, learners use their pulse rates as a measure of the effort expended in walking on different slopes.

In this activity, learners will create a drawing with dry erase markers and watch it come to life. Learners will explore chemistry, art and storytelling through this activity.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

Learn about friction and kinetic energy with this cool spinning toy.

In this outdoor winter activity, learners search for and create hibernation sites that will protect gelatin "animals" from freezing.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

In this activity about olfaction (9th activity on the page), learners smell 10 different items with different odors, including some edible food items.

In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.

In this activity, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.
