| These are the handouts that accompany the lab. Be sure to answer all questions using complete sentences. |
Students will be able to:
-identify characteristics of physical changes of matter.
- identify characteristics of chemical changes of matter.
-recognize examples of physical and chemical changes.
-record observations of physical and chemical changes of matter.
- identify characteristics of chemical changes of matter.
-recognize examples of physical and chemical changes.
-record observations of physical and chemical changes of matter.
Students completed the following bell ringer:
When an
object moves, its energy changes form. When a ball bounces, it has changing
amounts of potential energy and kinetic energy. Eventually, however, the ball
will stop bouncing. Why does the ball stop bouncing?
A. The ball's energy gets used up each time it bounces.
B. The mass of the ball is too small to allow it to continue its own
motion.
C. The ball's energy gets transferred to other energy types like
heat and sound that don't help it bounce.
D. The pull of gravity is stronger than the energy in the ball,
which makes the ball slow down to a stop.
Students reviewed HL 5.
Students completed a virtual lab on physical and chemical changes. The lab can be found at the following site:How are physical and chemical changes distinguished? You can see me for a copy of the handout for the lab. You
