Collect Oxygen Over Water
Source Institutions
In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.
Floating Candles
Source Institutions
In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.
Production of Oxygen
Source Institutions
In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.
Send Secret Messages
Source Institutions
In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.
Lifting Lemon
Source Institutions
In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.
Production of Carbon Dioxide
Source Institutions
In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.
Breaking Up with Combustion
Source Institutions
This activity teaches combustion as the interaction of a fuel source and oxygen.
Combustion
Source Institutions
In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.
Backyard Biodiesel
Source Institutions
In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.
