Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

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

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 design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

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 build a hovercraft using a paper plate, cup, and simple motor.

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

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

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

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

In this activity on page 4 of the PDF, explore the unique molecular structure and conductive nature of graphene. Learners construct a circuit with a battery and LED bulb.

In this activity, learners can play two card games related to endangered species, specifically North American amphibians.

In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.

In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this math activity, learners practice comparing fractions.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.
