Students will be able to:
use the information from hands-on investigations, the textbook and classroom discussions to
-explore energy changes that occur when a substance absorbs energy from its surroundings.
-imply that absorbing energy causes the temperature of teh surroundings to decrease.
Students reviewed HL 10 after completing the bell ringer.
HL 11 comes from the text, page 274 #1 a and b, page 276 #2 a and b, page 278 #1-3, and page 281 #3 a-c. This should be done on a properly headed sheet of loose leaf paper. Answers only.
Students then completed experimentation on a lab: melting ice to determine how energy changes occur. They melted ice in two temperatures of water and observed how the energy of the sytem changed by measuring the temperature.
We will review the graph tomorrow in class.
