Getting back to the beginning of the unit, learners use reactions with red cabbage juice to determine if solutions are acidic, neutral, or basic. This is a straightforward and classic investigation, but what you will appreciate is the...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Though the publisher designated this unit for use with third through eighth grades, this particular lesson would be best used with middle schoolers due to the specific measurement skills required. Basically, they set up the reaction...

Now that learners have been exposed to chemical changes, they learn that some take in heat and therefore, decrease in temperature. The same reaction that they have been investigating between baking soda and vinegar is revisited,...

By both demonstration and hands-on investigation, physical science fanatics come to know that some materials react when they come together. Adding vinegar to both baking soda and to baking powder, the difference between the two is clear....

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

Soften up an egg. Learners use vinegar to test for calcium carbonate in an egg shell and an antacid tablet and compare the reaction with vinegar to the reaction with water. In a second experiment, class members break down an egg shell...

Many scientists attempted alchemy for hundreds of years before a full understanding of metals became clear. Scholars take a penny and, through two different chemical reactions, make it appear to turn into silver and later gold. They...

When molecules of hydrogen and oxygen are combined, how does water form? Science scholars observe changes in kinetic and potential energy during a chemical reaction in an interactive. The resource features easy controls that allow users...

Time to turn the heat up on your next bonding lesson! Young chemists explore temperature, kinetic energy, and bonding through an interesting interactive. The controls allow individuals to vary the temperature, as well as pause progress...

Is this resource a great way for your class to observe bonding between oxygen and hydrogen? OH yeah! Scholars learn about the changes in kinetic and potential energy as molecules of oxygen and hydrogen interact. Kinetic, potential, and...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

A penny can be a much more valuable teaching tool that you might think. Whether you are teaching about chemical reactions, surface tension, the behavior of gases, or are just looking for engaging activities for early finishers,...

Challenge young scholars' understanding of thermochemistry with this skills-practice worksheet on Hess's Law. Given a series of five multi-step chemical reactions, students must determine the overall change in entropy...

Meant to follow an activity in which young chemists identified an unknown substance by chemical reactions, they now take their data and use it to determine which materials combine to make up baking powder. This lesson is one that can be...

Here is a nice, clean wrap-up activity for your chemistry class when they are studying chemical reactions . They experiment with different oils to make soap. To make it more fun, they are to imagine that they are part of a soap testing...

An overview of acid and base compounds and their reactions is presented with this handout. Pupils name compounds and write chemical formulas. They write net ionic equations and explain how acidic solutions might conduct electricity. This...

Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...

Focus on oxidation-reduction reactions with a review worksheet. Junior chemists answer short-answer questions before they write balanced half-reaction and full-reaction equations.

Biology learners should understand a few chemistry basics. Here is a worksheet that introduces them to the concepts of chemical reactions, molecular bonding, and the unique combination of properties that make water vital to life....

What is it that makes Mentos candy and cola such an explosive combination? Find out through scientific inquiry and experimentation. This presentation walks learners through the scientific process and allows them to speculate whether it...

Two versions of this handout are provided, the second with more detailed information on the same topics. Chemistry aces survey chemical reactions, heat energy transferred, and the action of enzymes by reading this resource. You can...

Scholars complete a crossword puzzle in this chemistry worksheet with 20 questions about chemistry concepts like atoms and chemical reactions.

Get your middle schoolers experimenting with dry ice. In the first activity, they place a piece in water and then use phenol red to identify its pH. In the second, they place a piece in a limewater solution and watch as the combination...
