Sharks: Taking a Bite Out of The Myth
Source Institutions
In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Photolithography
Source Institutions
In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.
2-Liter Landfill
Source Institutions
In this activity, learners gain a better understanding of how household/school waste breaks down in a landfill. Learners collect trash and then create miniature landfills in 2-liter bottles.
Seeing the World Through a Different Lens
Source Institutions
Learners participate in a variety of activities modeling different disabilities.
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.
Exploring Fabrication: Gummy Capsules
Source Institutions
In this activity, learners make self-assembled polymer spheres.
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
History of Siege Weapons
Source Institutions
In this activity (page 10 of the PDF) learners will explore the historical progression of siege weapons to gain an understanding of how the addition and modification of parts can change the efficiency
Causes and Effects of Melting Ice
Source Institutions
In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.
Maritime Munchies
Source Institutions
In this activity, learners follow simple historical maritime recipes to cook up hardtack and swanky, and then compare the foods they eat to what was served on ships in the past.
Recycling Rules: Understanding Recycling and a MRF
Source Institutions
In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.
Egyptian Measuring
Source Institutions
In this activity, learners compare the ancient Egyptian system of measurement, which was based on body lengths, to the customary and metric systems used today.
Monitoring Amphibians
Source Institutions
In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.
MarsBound!: Mission to the Red Planet
Source Institutions
MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.
Can Fishing
Source Institutions
In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.
Information Hiding: Sharing Secrets
Source Institutions
This activity about cryptographic techniques illustrates a situation where information is shared, and yet none of it is revealed.
Natural Selection Because of Different Color: Camouflage
Source Institutions
In this activity (p.5-6 of PDF), learners investigate natural selection. Learners discover that natural selection, which takes place over decades, can lead to altered populations within a species.
We Have Capture!
Source Institutions
Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.
