Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this activity, learners explore the engineering and principles behind working elevators.

In this activity (on pages 20-23 of PDF), learners build a model of a power plant using simple materials.

In this activity, learners use a fictitious map of "Tourist Town" and counters to problem solve how to place ice-cream vans on street intersections so that every other intersection is connected to one

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

Learners will follow a specific process to make their own paper using scrap paper, newspaper, or junk mail.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

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

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

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

In this activity, learners make self-assembled polymer spheres.

In this activity, learners describe an object they can’t see. After someone picks outs a few mystery objects and places them in a pillowcase, learners will investigate using only their hands.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

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

In this activity, learners design a scientific exploration mission to a planet or moon of their choice.

In this activity, learners use simple tools to build a bookshelf with a built-in bookend.
