Metal Reactions
Source Institutions
This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.
Surface Area
Source Institutions
In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.
Collect Oxygen Over Water
Source Institutions
In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.
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.
Mystery Powders
Source Institutions
Learners are given mysterious white powders and have to determine their identity with chemical tests.
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).
Luminol Test
Source Institutions
Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.
Nano Ice Cream
Source Institutions
In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.
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.
Wild Sourdough
Source Institutions
In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.
Forgotten Genius
Source Institutions
This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
Electrolysis
Source Institutions
Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.
First Impressions
Source Institutions
Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.
Power To Go
Source Institutions
Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.
As The Stomach Churns
Source Institutions
In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre
LEGO® Chemical Reactions
Source Institutions
This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).
Exploring Materials: Hydrogel
Source Institutions
In this activity, learners discover how a super-absorbing material can be used to move a straw.
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.
