Rover Races
Source Institutions
In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through
The Nose Knows!
Source Institutions
In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.
Print Hints
Source Institutions
In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.
Find the Best Way to Clean Oil off Bird Feathers
Source Institutions
In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.
Conservation Island
Source Institutions
In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.
Mission: Control!
Source Institutions
In this activity and game, learners will train to improve balance and spatial awareness by performing throwing and catching techniques on one foot.
Speedy Shelter
Source Institutions
In this design challenge activity, learners invent an emergency shelter that can fit a person and is sturdy and quick to build.
The Turing Test: Conversations with Computers
Source Institutions
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.
Scram or Freeze
Source Institutions
In this outdoor activity and animal-role-play game, learners discover and uncover the hidden world of "cryptozoa"—organisms such as spiders, salamanders and slugs that live under objects, like rocks a
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.
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.
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.
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
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
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
