Introduction - MST4.E.PS3.Introduction:
Students should describe, categorize, compare, and measure observable physical properties of matter and objects. Students’ initial efforts in performing these processes may yield simple descriptions and sketches, which may lead to increasingly more detailed drawings and richer verbal descriptions. Things can be done to materials to change their properties, but not all materials respond in the same way to what is done to them. Younger students emphasize physical properties while older students will recognize chemical changes. Appropriate tools can aid students in their efforts.
