CONTENT STANDARD: Physical Science
CONTENT TOPIC: Matter
CONCEPT: Matter undergoes physical and chemical changes.
CONTENT OBJECTIVE: 3D3.00 To understand physical and chemical changes in matter
INSTRUCTIONAL OBJECTIVES: The learner will:
TN COMPONENT OF SCIENCE: Unifying Concepts of Science
BENCHMARK: Changes can occur slowly or quickly within any system.
BENCHMARK: Materials may combine to form new materials. The properties of the new materials may be unlike the original materials.
Today we will learn about two kinds of changes: Physical change and chemical change.
PHYSICAL CHANGE and CHEMICAL CHANGE.) A physical change is change in size, shape, or state of matter. Ice that melts is still water, even though it has changed states. That is an example of a physical change.
A chemical change completely changes the object. A nail or tin can will rust. Your bicycle or other metal toy left out in the weather will rust. That is also a chemical change. A piece of paper that burns undergoes a chemical change.
1. apple - apple juice (physical)
2. chunk of wood - charred wood (chemical)
3. corn kernels - popcorn (physical)
4. smooth nail - rusty nail (chemical)
5. banana - banana chips (physical)
6. Whole sheet of paper - torn pieces of paper (physical)
