In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

In this activity, learners overlap the three primary colors to see how all other colors are made.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this activity, learners use a hand-made protractor to measure angles they find in playground equipment.

In this activity, learners work in groups to create a time line representing significant moments in their lives.

In this activity, learners use pattern blocks and mirrors to explore symmetry. Learners work in pairs and build mirror images of each other's designs.

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

Listen to the beat of gravity. By taking two strings with weights tied to them at different, yet uniform intervals, you can hear the uniformity (and rhythm) of gravity's accelerating pull.

Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.

In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

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.

This is an activity about reaction times. Just how quickly must an NHL goalie respond to save a shot, and how does your reaction time compare?

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this activity, learners design unique tiles and make repeating patterns to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.
