Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.

Excite classes with a STEM project-based learning lesson covering chemical reactions. Groups study the different types through simulations and hands-on activities. They pick one type (synthesis, decomposition, single displacement, double...

Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...

Take charge of your class and provide them with an electrical experience! Individuals investigate the basic principles of electricity and magnetism by creating a model to test electric current and the amount of electricity generated....

Fifth graders compare physical and chemical changes. They perform a simulation experiment/activity that replicates what happens in the stomach as food is digested by stomach acids.

In this chemical reactions worksheet, students experiment with hydrochloric acid and copper (I) chloride to identify the types of reactions they undergo with various other substances. They also observe the law of conservation of mass and...

In this changes worksheet, young scholars observe and record changes that occur in their every day life and classify these changes as either physical or chemical change. Students record their information in a graphic organizer.

Eighth graders explore the physical change of matter. As a class, they discuss their favorite super hero and determine if the hero undergoes a physical or chemical change. Students examine the change of state and phase change. In groups,...

In this recognizing different types of changes worksheet, students answer questions about such things as reversible change, irreversible process, climatic change, filtration process, physical change, and change in the state of a...

In this chemistry activity, students complete a crossword puzzle with 15 clues about both physical and chemical changes. Each clue lists number of letters for correct word.

In this chemistry worksheet, students are provided with the answers for a crossword puzzle containing 15 clues about physical and chemical changes.

Students examine the different changes in matter.  In this chemical change instructional activity students determine the amount of reactant made in a reaction using the law of conservation. 

Learners investigate the differences between a physical and chemical change. They observe various demonstrations involving physical or chemical changes, make predictions, and record what they see, hear, and smell.

In this chemical reactions worksheet, students answer follow up questions to a lab where they were observing chemical changes in reactions after mixing products such as hydrochloric acid and sodium bicarbonate. They answer six questions...

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.

Students investigate how water changes state. In this water lesson, students observe, measure, and describe water as it changes state. This lesson includes extensions which can be accessed via the provided web links.

Students find examples of physical and chemical changes using the five Web World Wonders camera sites.

Students examine physical and chemical properties of plastics, interfaces of plastics, and forms of plastics. In three lab activities, students discover the two characteristic responses of plastics to heating, thermoplastic or...

In this chemical reaction worksheet, high schoolers are given the details of an experiment where sodium chloride and silver nitrate are mixed in a chemical reaction. Students answer nine questions about the chemical reaction, they...

In this chemical reaction worksheet, young scholars experiment with soda and Mentos candy to observe a chemical reaction. Students describe the reaction, identify the investigation as descriptive or qualitative and make a prediction if...

Second graders explore weathering and how the water cycle plays a part in weathering. In this weathering lesson, 2nd graders put gravel and sugar cubes in a jar and shake, simulating weathering. Students use the scientific method to...
