In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

Coins are everyday objects which tell a lot about the people who use them.

In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.

Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

In this activity, learners make their own binary code bracelets by translating their initials into 0s and 1s represented by beads of 2 different colors.

In this activity, learners will make a marionette puppet and put on a show. Learners will explore color, design, fabrication and storytelling through this activity.

This activity requires a Pico Cricket (tiny computer).

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

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

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.
