Young scholars 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...

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

First graders discover that a chemical reaction is responsible for the effects seen with Crayola Color Wonder markers. They observe that the color changes are the result of a chemical reaction between chemicals in the Color Wonder paper...

Students 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.

The amount of energy Americans use doubles every 20 years. The first lesson in a 10-part series teaches scholars about different forms of energy. They rotate through five stations with hands-on activities or experiments at each in order...

How fun would it be to teach the concept of stoichiometry while allowing your chemistry class to assemble a classic campfire treat? This fun and engaging activity allows pupils to explore the principles of the chemical theory while...

In this triboluminescence worksheet, students use wint-o-green Lifesavers to observe a chemical reaction that gives off light. They break a lifesaver up with a hammer and make observations and they chew a lifesaver and make observations....

Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...

Students compare types of chemical change. For this chemical reaction lesson, students use a variety of household items to investigate different types of chemical change. Students will engage in a discussion about the dangers of...

In this chemical change worksheet, students conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...

Students study the concept of ice energy. In this ice energy lesson, students observe what happens when salt is sprinkled on a piece of ice before following a recipe to make two types of ice cream. They note the difference in the two...

Students investigate the chemical composition of pennies dated 1983 or later. In this chemical composition of American coins lesson plan, students scratch the surface of the penny to expose the zinc core. They put the penny in...

Fifth graders perform experiments to determine the identity of an unknown gas sample. In this chemistry lesson, 5th graders fill balloons with air, oxygen, hydrogen, and carbon dioxide. They use mass and reactivity to identify the gases.

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Surface area certainly surfaces as a variable for chemical reaction rates. Scholars perform an experiment to discover how the size of catalysts affect the rate of a chemical reaction. They record their results in tables and graphs to...

Students practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...

In this physical science exploration, small groups place a piece of antacid tablet into a film canister and step back to time how long it takes for the top to pop. They repeat the activity, altering either the amount or temperature of...

Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

High schoolers are introduced to chemical reactions, reaction rates, chemiluminescence, fluorescence and bioluminescence. They use glow sticks are used to demonstrate the effect of temperature on the rates of chemical reactions. Pupils...

Students visually observe chemical changes that occur when various solutions are combined. Teacher explains chemical reactions that are happening.
