Thermochemistry: Heat and Chemical Changes
What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...
Curated OER
Chemical Changes and Biscuits
Fourth graders investigate chemical changes in everyday life settings, such as cooking. They investigate leavening which is one of the classic chemical changes that people experience. Pupils observe leavening in biscuits with the...
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
Fun With Chemical Changes
Fifth graders observe and identify the differences between chemical and physical changes. In small groups they mix different substances together in glass beakers, and identify which had a chemical change, supporting their statements...
Curated OER
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
Chalk Fizz
Little chemists observe the effects of acid on calcium carbonate as an example of chemical change. As a demonstration you will place a raw egg in vinegar overnight, and as a lab activity, learners drip vinegar onto a piece of chalk....
Curated OER
Changes in Nature
The goal of this science lesson is to have youngsters be able to identify the physical and chemical changes in the carbon cycle, and water cycle due to weathering. The in-class inquiry/experiment is quite interesting and easy to...
Curated OER
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
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...
Curated OER
Changes All Around Us
Sixth graders, in groups, observe the difference between physical and chemical changes and create a collage of pictures to show the difference.
Curated OER
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
Chemical Fun
Fifth graders observe and conduct a variety of experiments to differentiate between physical and chemical changes. They mix cabbage juice with different liquids and record their observations on a chart. Students write down their...
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...

Physical and Chemical Changes - Making Toffee
Fourth graders make toffee to observe both physical and chemical changes. They determine what types of changes that are caused by the cooking process and which are chemical, and which are physical. In order to do this they follow a...
Curated OER
How to identify a physical change from a chemical change
Students identify the difference between some physical and chemical properties and compare some physical and chemical changes. They design an experiment to distinguish between a physical or a chemical property of their choice.
Curated OER
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.
Curated OER
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.
