  3. Physical and Chemical Changes • Physical Change: • Change in size, shape or state of matter without changing the identity of the matter. • Ex: Iron absorbs heat and changes from solid to liquid (state of matter change) and glows red. • Chemical Change: • Change of one substance to another. • Ex: Eggs decompose giving off hydrogen sulfide H₂S

  4. Physical and Chemical Properties and Changes • The teacher will assign one of the following: • Physical Property • Chemical Property • Physical Change • Chemical Change • Write down your assigned words. • Come up with your own example in a sentence. • Share your example with the class.
