    TOPIC: Physical and Chemical Properties

                         Physical and Chemical Changes

 

You are a newspaper writer assigned to investigate a series of interesting happenings at the science lab. The first part of your assignment will be to learn about physical and chemical properties and physical and chemical changes. Once you have found the necessary information, you will use your newfound knowledge to help determine just what went on at the lab.

 

 

 

Follow the links given on each topic to answer the questions below. Read each question and note key words. Then go to the web to investigate.  Write the answer on your paper when you locate it.
