In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

See what force a magnet has on a wire that has current running through it: will it push it, pull it, or will nothing happen? This is the foundation of a simple electric motor.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

What's a more compelling problem to solve than being stranded on a deserted island?

In this computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

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