Public Key Encryption: Kid Krypto
Source Institutions
In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.
Radioactive Decay of Candium
Source Institutions
In this simulation, learners use M&M™ candy to explore radioactive isotope decay.
Running in Circles
Source Institutions
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.
Earth Attractions
Source Institutions
In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.
Sound Representation: Modems Unplugged
Source Institutions
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.
High Rise
Source Institutions
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.
Touch Down
Source Institutions
In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.
Bright Lights
Source Institutions
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.
Cave in a Cup
Source Institutions
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
Partners in Pollination
Source Institutions
In this activity, learners identify the reproductive parts of plants and the animal (bee) structures involved in pollination.
The Muddy City: Minimal Spanning Trees
Source Institutions
In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.
Quick Frozen Critters
Source Institutions
In this activity, learners play an active version of freeze tag based on predator/prey relationships.
Cryptographic Protocols: The Peruvian Coin Flip
Source Institutions
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
Ice Roads: Steiner Trees
Source Institutions
In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.
Circulatory System Skit: Act out the Flow of Blood
Source Institutions
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.
Sea Turtle Populations
Source Institutions
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.
