BCRs were put on the exam review sheets to encourage appropriate student
collaboration and review of concepts in preparation for the entire exam (not just the
BCRs). Teachers should not address these BCRs during the course of their instruction
nor should they assist in preparing students for the BCRs during exam review.
Students are able to collaborate and use other resources to review and solidify concepts.
Students should be prepared to answer any of the following BCRs. Teachers will select
TWO from the list below on the day of the exam:
BCR: Energy Transfer
A cook places a pot containing 2.0 kg of water at a temperature of 20 ºC on an electric
burner. The burner is in direct contact with the pot. The water heats to boiling at
100 ºC.
Describe how the energy is transferred from the burner to the pot to the water. In your
response, be sure to include



the three methods of energy transfer.
a definition for each method.
a description of how each method is demonstrated as the water is heated.

BCR: Earthquake
Earthquakes are very powerful waves that are created when portions of Earth’s surface move
very quickly. Two different kinds of waves are created in an earthquake; transverse waves
and longitudinal waves.
An earthquake occurs very close to a body of water, like the one pictured below.

Compare the two kinds of waves (transverse and longitudinal) and how they would
cause the medium (the ground) to move differently.
The transverse waves would stop at the edge of the shore and the longitudinal waves
would continue in the water. Explain how the speed of the waves would change
when they enter the water, predict if the speed would increase or decrease when they
enter the water and explain why.
A person several miles away could see the earthquake before he or she could hear it
or feel the waves in the ground. Explain how this can occur, and what other kinds of
waves are involved.
