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
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...

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...
Curated OER
Physical and Chemical Changes
Students 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 from...
Curated OER
Physical and Chemical Changes
Learners 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...

The Law of Conservation of Matter
The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

A Snapshot of Science
Sixth graders explore physical and chemical changes. In this physical science lesson, 6th graders study vocabulary, discuss the changes they see in the world and look up information on chemical and physical changes. Students create...
Curated OER
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.

Chemistry Review
In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.
Curated OER
Matter
Students recognize that some changes to matter are reversible and some are not. For this matter lesson, students experiment a physical and chemical change. Students record experiment results in their science journals. Students act...
Curated OER
Changing Sugar
In this chemical and physical change worksheet, students use a sugar cube and observe its physical properties both when it is whole and after it is crushed. They heat the sugar cube and record 5 properties of the matter while being...

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...
Curated OER
Physical and Chemical Changes in Matter
Students investigate chemical and physical changes. For this chemical and physical changes lesson plan, students distinguish between a chemical and physical change when observing baking bread and hot dogs and bagels cooking on a grill....

Chemical Change in the Kitchen
Students examine chemical changes to food. In this chemical changes lesson plan, students make foods and observe the changes. The changes are recorded in an observation journal. Students photograph food they make at different stages in...
Curated OER
Physical and Chemical Changes
Students examine the different changes in matter. In this chemical change lesson students determine the amount of reactant made in a reaction using the law of conservation.
