Students design and create their own air-powered rockets, in this hands-on activity.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this activity, learners will investigate air and gravity through the use of various fabrics by through them in the air. Activity includes step-by-step instructions and extension ideas.

In this game, learners create flash cards with an image on one side (of an animal, for example) and the sound that animal makes on the other.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this hands-on engineering project, kids use two simple machines, levers and inclined planes, to construct their own pinball machines.

In this activity, learners make plates levitate! Learners build "hovercrafts" using simple materials to explore friction and motion.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square.

In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

During this interactive "survival" game, students learn about the importance of camouflage and how it helps animals to blend into their surroundings, as either predator or prey.

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

Space Guess Quest is a fun game that encourages participants to identify the many types of objects in space, from human-made spacecraft to nebulas, galaxies, stars, and worlds.

In this activity, learners will build a design and build a place for pollinators to drink from.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.
