After Reading the story identify each underlined statement as a physical property, physical change, chemical
property, or chemical change.
Phoebe loved to camp. On her last trip she and her friends chopped down firewood for the nightly campfire. As she
carried the firewood from the forest to the campsite she noticed the mass of the wood was extremely heavy. Phoebe
knew the logs would be very flammable because they were dry. Later in the evening as the group sat around the
burning logs and sang songs Phoebe smiled to herself, happy she had this opportunity.
chopped down firewood =______________________________
mass of the wood =___________________________________
burning logs =________________________________________ logs would be very flammable =__________________________
