In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity about electricity, learners identify closed and open circuits. First, learners examine and label diagrams of open and closed circuits.

In this activity, learners will build a stomp-powered launcher to blast off paper rockets they design. Materials can be found at a local hardware store or you may already have them at home.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

In this activity, learners investigate the movement caused by dispersion. Learners discover that dispersion is the random movement of objects.

In this activity, learners investigate the properties of graphene and graphite.

Build a house you can fit inside, using cardboard tubes.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

Learners develop an understanding of air pressure in two different activities.

In this story time program, young learners listen to the Dr.

In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, one person acts as a human robot while another acts as their developer by programming their actions.

This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.
