In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

In this online Flash game, learners test their engineering know-how, moving a collection of mechanical parts onto a board to make complete a system of parts that will move a ball from start to finish.

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

In this activity about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

In this activity, learners investigate passive solar building design with a focus solely on heating.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

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 thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.

In this math lesson, learners apply mathematical modeling to solve a real-world storage problem, in which a manufacturing company is given two options for storing oil barrels.

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

This activity is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Learners look through two cups with small holes in them to simulate what it'

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.

This is an online Flash game where learners can experiment with ballistics and how to compensate for the varying levels of gravity found on the planets of our Solar System.

In this math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.

Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.
