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

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

In this activity, learners repeat patterns in two and three dimensions to create tessellations.

In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

In this activity, learners discover how to rotate a flat shape into the third dimension. Learners draw and cut out a shape that has at least one straight edge on an index card.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

Light painting is a creative activity that involves creating striking images and illusions using a camera, a light source, and a little practice.

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

In this activity, learners repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

In this activity, learners manipulate film to create homemade movies. Scratch Film, also known as Direct Animation, is the process of drawing and scratching designs directly onto film.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
