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...

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...

In this chemical equations worksheet, students learn to balance chemical equations by counting the number of atoms of each element in the products and reactants and making them equal. This worksheet has 5 problems to solve.

The first of two worksheets methodically prepares chemistry novices for naming polyatomic compounds. It begins by having them acknowledge the number of each atom contained in a molecule. Then learners list the valence electrons for a...

In this metric units and properties worksheet, students determine the proper metric unit given a variety of measurements for specific items. They also identify chemical and physical properties and chemical and physical changes.

Chemical and physical properties give compounds an identity. Learners use the identity of a compound to predict what it is. By performing different tests like solubility, flame, heat, and reactions, individuals attempt to identify an...

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...

We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...

Students 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 an...

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...

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...

Only eight problems are on this competitive national chemistry exam. It required the balancing of chemical equations, solving stoichiometry questions, and more. This is part two of three of the national exam. Also available is a...

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,...

Young scholars 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

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...

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.

In this chemical equations worksheet, students practice balancing chemical equations by completing 21 equations. This worksheet includes an answer key.

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. 

Middle schoolers distinguish between physical changes and chemical changes. They comprehend that chemical reactions produce new substances with compositions and properites which are different than those of the starting materials. ...

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...
