Physical And Chemical Changes

Prepare your class for a quiz with these physical science review questions. Learners respond to 7 questions about ionic and covalent bonds, oxidation states, and chemical and physical changes. In addition, they name compounds and balance...

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

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...

A collection of ten slides reveals bright graphics and photos. Though the title is "Properties of Matter," the content is incoherent. You will find a couple of slides on chemical reactions, a few on the example of the S.S. Hindenburg...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

This is a classic chemical reaction to use in your science class. Starch and iodine mix to cause a color change. Discuss with aspiring chemists the chemical and physical changes that occur as you demonstrate.

Poor Sam! His graham crackers have undergone a physical change, so he can't make his s'mores! Mia explains that their molecules haven't changed, therefore they are still graham crackers. The two teens then discuss clues that would...

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.

Does gold really boil? Learn what temperature gold boils at and more using an animated activity about the properties of matter. Scientists learn about the properties of matter including examples of physical properties, the effect 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...
