If you have taught the first lesson plan 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...

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...

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...

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...

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....

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...

High schoolers divide substances into categories: made of chemicals/not made of chemicals, synthetic/naturally occurring, and toxic/nontoxic. They observe a mystery chemical and determine what precautions they need to take when handling...

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...

College-level or AP chemists use phthalic anhydride to synthesize two different polyesters, one linear and one cross-linked in structure. A detailed materials list and well-written procedures are provided on a lab sheet. Learners write...

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,...

Students examine the effect of hazardous chemicals on humans. They discover how the chemicals are cleaned up and the facilities in their neighborhood. They identify federal and local agencies that oversee environmental hazards

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

Students use sight, touch and chemical test kits to evaluate and classify soil types. They determine the organic content, soil pH, conduct visual analysis and nutrient tests of a variety of soil samples from various sources.

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 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...

Here is a nice, clean wrap-up lesson 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...

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.

Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

Students measure the heat of physical and chemical changes in reactions.  In this chemistry lesson students determine at what extent changes emit or absorb heat. 

High schoolers conduct labs to gain an overview of chemical reactions. They observe examples of synthesis, decomposition, single displacement and double displacement reactions. They identify certain products by the use of litmus and...

Students investigate the art and science of pyrotechnics.  In this chemistry and computer lesson, students learn about the chemical basis of fire and structure of fireworks.  Students then apply their knowledge in...

Tenth graders explore the importance of pesticides as chemical tools. The chemistry of a pesticide is important for understanding the composition of the product, the classification of pesticides according to their use and the...

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...

Experiment with chocolate coating on cookies! What a delightful way to learn about food processing and chemical engineering. Throughout this activity, groups collect measurements and make calculations. They conclude by writing...
