Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

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.

Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.

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

In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.

In this activity, learners construct a home-made journal with simple, everyday materials.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

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

In this activity, learners will explore how computers represent pictures using pixels.

In this Cyberchase activity, learners make carpenter's squares and use them to measure square corners. Learners cut out the carpenter's square template and attach it to tagboard.

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

In this activity about light and perception, learners create pictures in thin air.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

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

Learners create an Incan counting device called a quipu (pronounced kee-poo).

In this activity, learners imagine what the world might look like if we could build an elevator to space!
