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...

Students recognize the concepts of the five general types of chemical reaction: combination, decomposition, single replacement, double replacement and combustion. They practice classifying chemical equations and determine the moles in a...

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....

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

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...

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...

If you have taught the first lesson in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known and...

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...

Students conduct experiments by mixing baking soda and vinegar.  In this chemistry lesson, students complete three different experiments involving these two substances. They find that the chemical reaction does not change and will...

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.

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...

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...

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...

Melting and burning might seem like opposites, but both exist as common examples of exothermic reactions. Scholars work with three different exothermic chemical reactions to determine the enthalpy changes. They measure and mix chemicals,...

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...

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....

Students explore the different types of reactions and write the chemical equations for them.  In this chemical lesson students identify different reactions and predict the product outcome. 

Students explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

A list of word reactions are given. Your class should write balanced equations, along with giving the reaction type and physical states.

Tenth graders observe various chemical reactions in the lab. For this chemistry lesson, 10th graders list the indications that a chemical reaction took place. They give real life examples of reactions they see everyday.

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...

In this chemical reactions worksheet, high schoolers experiment with reactions between 4 different metals with water, acid and air. Students make observations of copper, iron, zinc and magnesium with water, acid and air. They write an...
