What is the code word for the 5 forms of energy?

• MENDS

• STEMS

• MELTS

Which of these changes to the electric circuit shown above will cause the lightbulb to light up.

• Adding a switch and more wire so that the current can flow more easily

• Turning one battery so that its positive end connects to the other battery's negative end

• Making the length of wire the same on both sides of the lightbulb

The picture shows an example of a simple circuit. The lightbulb will not light up because...

• there is no switch in the circuit.

• the wires do not form a closed circuit.

• the wires are too long.

• the lightbulb is broken.

The picture shows a child standing in a swimming pool. Why does the lower part of the child appear so much different in size from the upper part? (5.6C)

• The light rays that travel through water and then into air are refracted.

• The light rays that travel through water and then into air are enlarged.

• The light rays that travel through air and then into water are reflected.

• The light rays that travel through air and then into water are reduced.
