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 (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

In this math lesson, learners identify, describe, and construct the five regular polyhedra.

In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this math lesson, learners arrange pattern blocks to create tessellations and to explore geometric patterns. Learners first explore making patterns with a variety of pattern blocks.

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.

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

In this math lesson, learners identify the relationship between the number of sides in a regular polygon and the number of struts needed to make each polygon rigid.

In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.

In this activity, learners explore how mirrors reflect light and change the way we see things.

In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.

In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

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 experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.
