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 will experiment with textures, shapes, and materials and create their own unique masterpieces.

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

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

In this activity, learners manipulate film to create homemade movies. Scratch Film, also known as Direct Animation, is the process of drawing and scratching designs directly onto film.

In this activity, learners use binoculars (or a telescope) to identify and track sunspots. If using binoculars, learners need a pair that can be secured on a tripod.

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 activity, learners use objects they find on a nature and water to make creative frozen sculptures.

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

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

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

Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.

Light painting is a creative activity that involves creating striking images and illusions using a camera, a light source, and a little practice.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.

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

In this activity, learners will experiment to find how long it takes to compost paper. They will create their own compost container and test different variables.

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 chemistry demonstration, learners will discover that phenolphthalein is an acid/base indicator. One learner will read a poem about four witches making a potion.
