Source Institutions
This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.

Plaster Casts
Source Institutions
In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.

Burst a Bubble
Source Institutions
In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

Snowstorm in a Jar
Source Institutions
In this activity, learners will experiment with density and chemical reactions to create a flurry activity.

Bend a Carrot
Source Institutions
In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

Shaving Cream Marbling
Source Institutions
In this activity, learners will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.

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.

Glow Fast, Glow Slow: Alter the Rate of a Reaction!
Source Institutions
Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

Sugar/Salt Crystals
Source Institutions
In this chemistry activity (page 1 of the PDF), learners will observe a physical change.

Carrying Charges: Testing for Conductivity
Source Institutions
Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
