In this chemical reaction worksheet, students practice balancing equations. This worksheet has 60 chemical equations to balance.

Students discuss transition metals, their properties, and where they are located on the periodic table as well as why transition metals are ideal for coins. After discussion, they conduct an experiment using copper in the form of old...

Students participate in a hands-on activity in which they observe the effect of temperature on the rate of chemical reactions. Using Alka Seltzer tablets in different temperatures of water, they record the amount of time it takes each...

Students participate in a hands-on activity in which they observe conditions that are most conducive to the rusting of iron. They set up an experiment with 8 different nails in different situations with one of them acting as a control....

Learners are taught that combustion of carbon in charcoal briquetts produces heat and light. They are shown how to find single displacement and double displacement. Students solve problem set of single and double displacement.

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...

In this chemical reactions activity, students are given the reactants of equations and must complete each equation by writing the products and balancing the equation. They must also identify the type of reaction.

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...

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...

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...

In this chemical reaction worksheet, students write 11 balanced equations for 11 word equations, and complete word equations and balance chemical equations for 13 chemical equations.

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,...

Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...

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. 

Students discover stoichiometric relationships in chemical equations. They review mole to mole conversions. They understand mass/particle conversions. They perform a lab to reinforce stoichiometry.

In this reaction rates worksheet, students solve eight multiple choice problems about chemical reactions and their rates. They determine what species would slow reactions, they apply concepts of activation energy to reactions, they...

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...

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...

Sixty multiple-choice questions test on a variety of first year chemistry subjects. In order to succeed, exam takers must be competent with properties of elements, stoichiometry problems, gas laws, bond dissociation, and types of...

Students describe and define chemical reactions. They design a laboratory experiment, collect data and analyze data.

In this enthalpy equation worksheet, students are given 3 examples of chemical reactions. Students then respond to 4 practice problems and 1 challenge problem in regard to heat and energy change and release.

Students explore how chemical reactions occur. After a brief discussion of household chemicals and how they work, students prepare a solution of invisible ink. Students create a message with their ink and watch the reaction as their...

In this chemistry worksheet, learners look at the diagrams for the chemistry reaction. Then they write down the correct chemical reaction.

Middle schoolers observe chemical reactions using post-1982 pennies. They observe the reaction of an acid with zinc but not copper under the same conditions over a two week period.
