In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

In this activity, learners use a fictitious map of "Tourist Town" and counters to problem solve how to place ice-cream vans on street intersections so that every other intersection is connected to one

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d

In this activity, learners investigate the properties of graphene and graphite.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this activity, learners use microarray technology to determine which genes are turned on and off at various points in the differentiation of pluripotent stem cells on their way to becoming pancreat

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

In this activity, learners make self-assembled polymer spheres.

This activity explores what it means for a computer to be intelligent and introduces the topic of what a computer program is and how everything computers do simply involves following instructions writ

In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

In this activity, learners construct cars that are powered by hand-made, electric propellers.

In this activity (page 10 of the PDF) learners will explore the historical progression of siege weapons to gain an understanding of how the addition and modification of parts can change the efficiency

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.
