Learners construct and use a "real" 3D coordinate system out of balsa wood and foam core. They will then be able to locate coordinates in space.

In this engineering activity, young learners investigate multi-level buildings.

In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this activity, learners build small animated toys that move.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.
