Pneumatic Trough
Source Institutions
In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.
Cookie Mining
Source Institutions
In this activity, learners explore the economics of coal mining as you they use fake money to purchase mining tools, attempt to carefully mine their cookies, sell their chocolate chip ore, and try to
Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.
Whose Fault Is It?
Source Institutions
In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.
Aerogel

Los Momentos de Mixing in Math son actividades de 5 a 10 minutos que mantienen a los chicos ocupados, aprendiendo sobre el mundo, y usando matemáticas por su cuenta.
Mystery Sand
Source Institutions
In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.
Home Water Audit
Source Institutions
This activity offers learners and their families several ways to raise their awareness together about home water.
Waves: An Alternative Energy Source
Source Institutions
In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.
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
Breaking the Code: Mayan Math
Source Institutions
This is a lesson plan for an activity in which learners, playing the role of archeologists, use math concepts about number bases to decipher the Dresden Codex, an ancient Mayan document.
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.
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.
Backyard Biodiesel
Source Institutions
In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.
