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...

Chemistry whizzes test the change in water temperature produced by a burning candle and the change in acid temperature produced by magnesium metal. With these two laboratory activities they explore heat produced during chemical...

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...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

Start this series of lessons with a bang! Five exothermic reactions are outlined in this resource, including a demonstration that produces both light and sound. In the lab, chemistry apprentices record temperature changes, make hand...

Scratch and sniff an introduction to organic chemical reactions. A creative lesson has individuals study the esters commonly used in scratch-and-sniff stickers and advertisements. Following the lab procedure, scholars create the organic...

Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

Learners 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...

Learners perform a series of experiments on copper to produce a variety of copper compounds. In this chemical reactions of copper lesson plan, students use copper wire and nitric acid to produce copper nitrate. They then form a hydroxide...

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....

Collaborating chemistry pupils observe that temperatrue increases the movement of dye throughout water, stirring increases the dissolving rate of sugar cubes, and concentration of solutions increases the chemical reaction rates. These...

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...

Students observe chemical reactions that produce obvious effects. They begin by exploring a different substance every day for one week. They compare the substances and examine how substances can be solids, liquids, or gases.

Students see evidence of chemical reaction and follow the scientific method to hypothesize, observe, and reach conclusions. They conduct a series of egg based experiments such as forming crystals and complete journal activities as a...

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...

Students investigate chemical reactions. In this chemistry lesson, students burn magnesium and record the mass. Students list five chemical reactions they see everyday.

Fifth graders, in groups, complete two activities in which various substances are combined, resulting in a very different substances. They discuss reactants and products and chemical reactions.

Students complete an experiment with Alka-Seltzer and reaction rates. They control the rate in which gases are allowed to escape. They test their predictions and observe what happens during the experiment.

Introduce high schoolers to chemical reactions with this series of activities. In a little over an hour, scientists observe four gas-producing reactions: the combination of hydrochloric acid and sodium hydroxide, placing pasta in...

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...

Colors are more than just a pretty effect. Learners explore what color change means in terms of chemical properties and reactions. They create a pH solution using cabbage leaves and observe the changes when acids and bases are added. 

Understand how chemical reactions recombine atoms to create the "chemicals of life". An experiment, showing the basic chemical reactions of an iron nail or a match, helps young children start their understanding of permanent changes.
