Wheat Evolution: Dough Rising and Baking
Source Institutions
In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

Milk Plastic
Source Institutions
In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

Column Chromatography
Source Institutions
In this activity, learners separate the components of Gatorade using a home-made affinity column.

Nuclear Fusion
Source Institutions
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

Instant Ice Cream with a Dry Ice Bath
Source Institutions
In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

Crash Landing!
Source Institutions
In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.

Build a Big Wheel
Source Institutions
In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

Having a Gas with Cola
Source Institutions
In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

Yeast Balloons: Can biochemistry blow up a balloon?
Source Institutions
Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

Red, White and Blue II Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

Exponential Models: Rhinos and M&M’s ®
Source Institutions
In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

Multi-Variable Relations: Stressed to the Breaking Point
Source Institutions
In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

Smell the Difference
Source Institutions
In this two-part activity, learners use household items to smell the difference between some stereoisomers, or molecules which are mirror images of one another.

Ice Cream
Source Institutions
In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

Molecular Menagerie
Source Institutions
In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

Enzyme Action
Source Institutions
In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

Ship the Chip
Source Institutions
In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

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.

Radioactive Decay of Candium
Source Institutions
In this simulation, learners use M&M™ candy to explore radioactive isotope decay.
