Based on the before, how many boxes SHOULD BE in the total after?

Mathematical Equivalence

OFF

Based on the before, if there are 3 boxes for the battery, how many should be in the total?

Mathematical Equivalence

OFF

What actually belongs in the system? Move each item to the appropriate category.

Groups:

(a) Object in system

,

(b) Energy indicator (not in system)

• fan

• wires

• light

• motion

• battery

• sound

In the before, the first indicator is listed as "battery." Which of the following would be the correct way to write the indicator?

• electricity

• battery of electricity

• EW electricity of battery

• sound of battery

There is a lot wrong with this LOL - choose one thing done correctly.

• EW motion in the after

• boxes in the L after match the total

• totals before and after match

• objects in the system

In looking at the after, what is something done incorrectly

• fourth column of boxes with no indicator labeled

• boxes in the L after match the total

• too many indicators listed

• motion is not an indicator in this scenario

To make an energy conservation diagram for this video, could you use "EW mass battery" as an indicator?

• Yes, the battery loses mass as the fan spins.

• No, we did not measure the mass, so we do not know for certain.

• Yes, the light and sound use up the mass of the battery.

• No, energy does not have mass so it cannot be used as an indicator.
