Exploring an Ecosystem
Source Institutions
In this ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.
Community Wind Project
Source Institutions
In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.
A System of Transport
Source Institutions
In this activity about the human heart (on page 5 of the PDF), learners work in teams to simulate the volume of blood moved through the circulatory system by transferring liquid into--and through--a s
Nature Walk
Source Institutions
In this activity, learners take an indoor nature walk and discover various objects that have been brought in from the outdoor environment.
Computation and Estimation: Roll Out The Barrel
Source Institutions
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.
What-a-cycle
Source Institutions
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.
Population Study Game: Oh, Deer!
Source Institutions
In this activity, learners model a population of deer and see how the number of deer changes over time.
Investigating the Insides
Source Institutions
In this activity, learners work in teams to investigate the composition of unseen materials using a variety of tools.
Moving and Working in Space
Source Institutions
In this activity, groups of four learners must complete a set of four manual tasks. The restrictions are that they must complete the tasks in a limited time while wearing garden or rubber gloves.
Fuzzy Worms
Source Institutions
In this activity, learners explore the concepts of natural selection and observable traits in a game that can be played at home.
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
How the Mushroom Got Its Spots
Source Institutions
In this activity (p.26 of PDF), learners discover why mushrooms have spots. Learners use a balloon, toilet paper, and water to simulate what happens as mushrooms grow.
Trail Impact Study
Source Institutions
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.
Follow the Scent
Source Institutions
In this outdoor, sensory activity, learners role play as animals trying to identify their "family's" scent and locate their "territory." Learners mark their territories and sniff out other territories
Do Sweat It!
Source Institutions
In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.
Challenge: Microgravity
Source Institutions
In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod
Cool It
Source Institutions
In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.
Seeing Is Believing
Source Institutions
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'
Artificial Intelligence: The Intelligent Piece of Paper
Source Institutions
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
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.
