Chemical Footprint—Family Activity
Source Institutions
In this multi-part activity learners examine non-point water pollution.
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.
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.
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).

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.

Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.
Yeast Balloons
Source Institutions
Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

Home Mycology Lab
Source Institutions
Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.
Hot and Cold: Endothermic and Exothermic Reactions
Source Institutions
Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.
It's A Gas!
Source Institutions
Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.
All Mixed Up!: Separating Mixtures
Source Institutions
Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

Lotus Leaf Effect
Source Institutions
This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.
Concentrate: Concentrations and Reaction Rates
Source Institutions
Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.
