Change in Temperature - Exothermic Reaction
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...

Matter and Energy
Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Chemical Changes to Matter
Students analyze the causes of corrosion. In this chemistry lesson, students investigate what is necessary to cause chemical changes in matter. Students discover the causes of rust and tooth decay.
Curated OER
Physical and Chemical Changes
Students investigate chemical and physical changes. In this physical and chemical change lesson plan, students perform 3 experiments in the lab to observe changes in matter. They determine that no new substances are formed in physical...

Physical or Chemical- That is the Question!
Students observe the differences between physical and chemical changes in properties. Through the use of an interactive presentation, the students compare and contrast the changes and provide supporting examples of each type of change.

Chemical Change in the Kitchen
Students examine chemical changes to food. In this chemical changes instructional activity, students make foods and observe the changes. The changes are recorded in an observation journal. Students photograph food they make at different...
Curated OER
Physical and Chemical Changes
Young scholars observe examples of physical changes that can take place between the three states of matter and develop common sense and intuition in distinguishing between chemical and physical changes. They observe diagrams on the board...

Physical and Chemical Change of Six White Substances
Students investigate chemical and physical changes in reactions. In this chemical and physical change lesson plan, students mix 6 different white substances with water, vinegar and iodine. They make hypotheses about each substance and...
Curated OER
Chemical Changes
Fourth graders examine and identify chemical and physical changes in a variety of substances. They observe a vinegar and baking soda demonstration, and a water, laundry detergent, and Epsom salt mixture demonstration. They discuss the...

The Cycle of Matter
An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form.

Cents-ible Chemistry-Analysis of the Metal in a Penny
Students determine the base metals and surface metals in a penny. In this analysis of metals lesson plan, students determine the density of five pennies minted in different years. They use different chemicals such as hydrochloric acid,...
Curated OER
Matter
Young scholars recognize that some changes to matter are reversible and some are not. In this matter instructional activity, students experiment a physical and chemical change. Young scholars record experiment results in their...

Physical and Chemical Properties of Matter
Learners identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.

Changes In Matter, "The Big Chill"
Third graders investigate why ice cream does not go through any chemical changes when it is exposed to physical changes. They describe the three states of matter in either written or verbal form. Then students experiment with ice cream...

Chemical Changes
Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.

What's the Matter? (Living and Non-Living Things)
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.
