Cleaning with Dirt
Source Institutions
Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
Chemical Footprint—Family Activity
Source Institutions
In this multi-part activity learners examine non-point water pollution.
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.
Mercury in the Environment
Source Institutions
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.
Trading Places: Redox Reactions
Source Institutions
Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.
Let's Clone a Mouse, Mouse, Mouse...
Source Institutions
Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.
Hold a Hill
Source Institutions
In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.
Currently Working: Testing Conductivity
Source Institutions
Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.
Jam Jar Jet
Source Institutions
In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.
Forwards and Backwards: pH and Indicators
Source Institutions
Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).
Solar Structures
Source Institutions
In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.
Plugged in to CO2
Source Institutions
In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.
Toxic Popcorn Design Challenge
Source Institutions
In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.
Shipping for Survival
Source Institutions
In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.
Engineered Music
Source Institutions
In this activity, learners explore how musical instruments are engineered.
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.
Pesticides and Eggshell Thinning
Source Institutions
This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.
Whose Fault Is It?
Source Institutions
In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.
Arctic Sea Ice
Source Institutions
In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.
Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.
