Chemistry: Balancing Chemical Equations
Eighth graders practice balancing chemical equations. For this chemistry lesson, 8th graders explain why it is necessary to balance equations. They complete practice worksheets individually.

Physical and Chemical Changes
Eighth graders distinguish between physical and chemical change. In this chemistry lesson, 8th graders observe a series of demonstrations showing physical and chemical changes. They identify the signs that a chemical reaction took place.

Acid and Base Testing
Students study descriptions of indicators and the way they are used to identify acids and bases. They use this information to determine if unknown solutions are acids or bases.

Acids And Bases -- Universal Indicator
Eighth graders design and perform an experiment that uses a Universal Indicator Color Guide to measure the strength of acids and bases. They also determine happens when acids and bases are mixed together. They decide which of three...

Serc: Conservation of Mass Gum Lab
Students investigate whether or not chewing gum should be considered eating using the law of conservation of mass to reason that the portion lost of the original mass of gum must be swallowed.

Middle School Chemistry: Lesson Plans: What Is a Chemical Reaction?
After observing a demonstration of a chemical reaction between a burning candle and the oxygen in the air, learners use atom model cut-outs to model the reaction and see that all the atoms in the reactants show up in the products.

Middle School Chemistry: Controlling Amount of Products in a Chemical Reaction
Students analyze the chemical equation for the reaction between vinegar and baking soda. They observe that the gas produced in the reaction is also part of the products of the written chemical equation.
