In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

In this activity, learners will explore how metals react with each other. They will see these metals change before their eyes as they coat a paperclip with the copper taken from a penny.

In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.

This is an activity about acid-base reactions using eggs and vinegar. Learners place eggs inside a container of vinegar and leave to soak overnight.

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.

Learners write their initials by applying different clear "magic ink" solutions to separate pieces of paper and then "develop" the inks with other clear solutions.

In this chemistry activity (on page 2 of the PDF), learners corrode a penny in a cup with vinegar, salt water, and a source of iron (nails, paper clips, or twist ties).

In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this chemistry activity, learners use mossy zinc (or a galvanized nail) and hydrochloric acid to generate hydrogen gas and test some of its properties.

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.

In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.

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

In this activity, learners separate the protein from milk and and use it to make their own glue.
