We were in the lab today watching a demonstration on clues about physical and chemical changes. We learned that physical changes do not change the chemical nature of the substance, like ripping a piece of paper or popping a balloon. Chemical changes do cause the substance to become a new or different substance, like rusting and burning.
If you were absent go to the notebook tab and look at the notes there to complete yours. We put the notes from the demonstration in our science notebooks. Demo Notes Comments are closed.
