In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this activity, learners walk the sides and interior angles of various polygons drawn on the playground. As they do so, learners practice rotating clockwise 180° and 360°.

In this activity, learners create a cylindrical mirror to see themselves as others see them.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners build a tool called an inclinometer that can find the height of any distant object, from a tree to the North Star.

In this calculus activity, learners use a classic problem of geometrical probability to find an important mathematical constant (pi).

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

In this activity, learners explore how pictures change in curved mirrors. Learners make cylindrical mirrors by wrapping Mylar around soda cans.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this activity, learners arrange triangles together to make patterns to create paper quilts. Learners experiment with arranging the triangles in different ways to make various designs.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this math activity, learners observe and sketch cracking patterns in pavement.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this activity, learners slide shapes to create unusual tiled patterns.
