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 group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.

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 listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

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 (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

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

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

In this activity, learners play an active version of freeze tag based on predator/prey relationships.

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

In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice.
