Rocks are made of minerals, and minerals often have crystal shapes. In this fun activity about geometry in nature, learners create their own crystal shapes out of paper.

Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

In this activity, learners design a flag for a chosen or assigned planet. The instructions include information about flags on Earth, and a list of flag references.

In this activity, learners investigate the behavior of magnets. Learners create a "wonder wand" with a magnet so they can move a skater around.

This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.

In this activity learners create patterns of hair beads.

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

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.

Discover geometry by creating shapes from loops of paper. In this activity, paper loops transform to give you totally new structures when you cut them.

Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

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

Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

In this activity, learners investigate feeding relationships. Learners complete a food web and then make a mobile to represent a food chain.

In this math lesson, learners practice reading charts and graphs by creating and interpreting glyphs.

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 (located on page 2 of PDF), learners explore alternative uses of a simple paper cup, dubbed a "mystery item." Learners act as detectives and explore the properties and functions of th

Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.

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