In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.

In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

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

In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

In this activity, learners identify the reproductive parts of plants and the animal (bee) structures involved in pollination.

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 yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

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 act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity, learners work in teams to investigate the composition of unseen materials using a variety of tools.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

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 act out the flow of blood in the human body! A great way to get learners up and moving while learning about the circulatory system.
