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.
Hot Equator, Cold Poles
Source Institutions
In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.
Wheat Evolution: Sedimentation Testing
Source Institutions
In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.
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.
What Smart Metal!
Source Institutions
In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
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.
Egg Osmosis
Source Institutions
Visitors observe three beakers. One beaker contains an egg immersed in vinegar. Visitors observe carbon dioxide gas escaping from the shell as the calcium carbonate reacts with the vinegar.
DNA Extraction from Cheek Cells
Source Institutions
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.
Chemistry Is Colorful
Source Institutions
In "Chemistry is Colorful" learners explore different materials through paper chromatography.
Edible Glass
Source Institutions
In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.
It's a Gas!
Source Institutions
In this activity, learners explore two properties of gases: gases take up space and exert pressure. Learners assemble two flasks and a beaker, connecting them with stoppers and tubing.
Crocodiles
Source Institutions
Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.
How Many Pennies?
Source Institutions
In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
What Does Spit Do?
Source Institutions
Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.
Shape Up!
Source Institutions
In this activity (pages 8-9), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
Taking Its Temperature
Source Institutions
In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
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.
Window Under Water
Source Institutions
Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.
Starch Breakdown
Source Institutions
Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.
