Gas Production: Blow up a balloon!
Source Institutions
In this classic reaction, learners baking soda and vinegar in a soda bottle to produce carbon dioxide (CO2) gas. This gas inflates a balloon.
Create Gas
Source Institutions
Learners mix vinegar and baking soda together in a bottle to create a chemical reaction. The reaction produces a gas, carbon dioxide, which inflates a balloon attached to the mouth of the bottle.
Snowstorm in a Jar
Source Institutions
In this activity, learners will experiment with density and chemical reactions to create a flurry activity.
Change in Temperature: Endothermic Reaction
Source Institutions
Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.
Diving Submarine
Source Institutions
Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.
DIY Bath Bombs
Source Institutions
In this activity, learners will explore acid-base reactions and create their own bubbly results.
Mixing and Unmixing in the Kitchen
Source Institutions
In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.
Atoms and Matter (K-2)
Source Institutions
In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.
Pop Rockets
Source Institutions
Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.
DIY Elephant Toothpaste
Source Institutions
In this activity, learners will experiment with catalysts to create an at-home version of elephant toothpaste.
Exploring Properties: Surface Area
Source Institutions
This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
Rockets Away
Source Institutions
In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.
Breaking Up with Combustion
Source Institutions
This activity teaches combustion as the interaction of a fuel source and oxygen.
Flubber: Make a polymer!
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.
