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

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

This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.

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

In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

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

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

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.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

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.

In this project, students explore how levers work, by making a puppet with moving limbs.

In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

Students design and build their own parachutes in this hands-on engineering project.
