In this activity (on page 2 of PDF), learners make their own totem poles out of recycled materials.

In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.

In this hands-on activity, learners make New Year's Eve party hats out of wrapping paper. Learners use symmetry and measurement to cut out shapes they need to assemble the hats.

In this outdoor art/environmental activity, learners create designs that will attract attention to animals and plants in particular habitats, and then test whether their designs attracted the "right"

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 activity, learners observe what would happen to their bodies if they went to outer space without a space suit.

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.

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

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 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 model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.

In this activity, learners separate the protein from milk and and use it to make their own glue.
