Physical And Chemical Changes

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Quiz the class on what they know before you teach it. This assessment will give you an idea of what basic scientific concepts are known to your learners. Physical change, state of matter, and basic plant and animal needs are covered.

Heat is a gateway to change. While exploring the properties of baking powder, pupils learn that some heat-related changes are permanent. Using an animation, the lesson uses chocolate chip cookies as an example.

Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Engaging hands-on science lessons for grades 2-6 on chemical and physical changes.

Thinking back to the last time you taught a lesson on chemical changes ... was there no reaction? Check out an explosive video to put some spark back in your instruction! The narrator of the video guides you through the expectations, as...

Students will learn the difference between physical and chemical properties of matter.

Second graders explore the concept of law of conservation of mass.
