BONUS ROUND 100 POINTS
Name an object in which you can see your reflection and another object that does not produce your reflection.
TELL WHAT CAUSES THE DIFFERENCE. I can see my reflection in the shiny side of a CD because the reflected light travels together in the same direction. I can’t see my reflection on the top of my desk because the reflected light is in different directions.

BONUS ROUND100 POINTS
Explain the difference between an open circuit and a closed circuit.
A closed circuit is a circuit with no breaks or gaps, and it allows for the electricity to flow. An open circuit is where there is a break in the circuit which will not allow for the electricity to work.
