In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

Teams of learners use a series of stick figures made from pipe cleaners to model a dance routine. Then, they use this model to communicate to another learner who performs the dance routine.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

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

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

In this activity, learners will build the highest tower they can out of recycled materials.

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

In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.
