In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

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 activity, learners construct a small "air cannon," and use its airflow to put out a candle (lit with the help of an adult).

In this activity, learners will make their own "ball bearing" with two jar lids, marbles, and some household supplies.

In this lab (Activity #1 on page), learners compare bacteria growth on two petri dishes containing nutrient agar: one that has been touched by a finger washed only with water and one that has been tou

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this activity, learners use maps to locate the Arctic region and use a word game to discover the types of resource people need to survive in the extreme climate.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

In this activity about magnetism (page 11 of the pdf), learners will experiment with magnets to explore how opposite poles attract and similar poles repel in magnetism.

In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.
