In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.

In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.

This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

In this activity, pairs of learners model how scientists use craters to determine the ages of lunar surfaces. One partner keeps time while the other creates a painting for the other to interpret.

In this activity, learners make a photographic image—without a camera!

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

In this activity, learners watch a figure "magically" float up through the air.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

These math posters have questions written on them, such as: How many colors can you name in a minute? or How many seconds can you balance on one foot?

In this activity on page 6 of the PDF, learners use glue instead of glass to create artwork that can be hung in a window.

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 will explore how computers represent pictures using pixels.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this activity (p.24 of PDF), learners make paper with fungi. Learners discover that paper is basically a flat mat of fibers.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

Make two firefly lanterns, then program them to blink to one another and change colors.

In this activity, learners will experiment with textures, shapes, and materials and create their own unique masterpieces.
