Part 1. Paulie builds this circuit for a fan and a heater. His teacher challenges him to change the design to meet these criteria: The design allows the heater to work only when the fan is on, and the heater can be shut off so only the fan works. Paulie comes up with these four possible design changes. Which design changes MEET the criteria? Select TWO Answers
Design A
Design B
Design C
Design D

Look at the two circuit diagrams. In the circuit on the left, the light bulb is lit up. In the circuit on the right, the light bulb is not lit up. Why is the light bulb on the right not lit up?
The circuit is missing a switch.
The filament is broken, so the circuit is closed.
The circuit needs more batteries.
The filament is broken, so the circuit is not a complete loop.
A complete electrical circuit is shown. It is a functioning circuit that is causing the light to be on. What could you do to the switch or the battery to make this a non-functioning circuit? Choose either the switch or the battery and explain your answer.
In the circuit shown, the light bulbs are lit up and the bell is ringing. Different places on the circuit are marked with numbers. Linda wants to be able to turn off the bell without turning off the lights. What should she do?
She should connect a switch at location 2.
She should connect a switch at location 3.
She should connect a switch at location 1.
She should connect a switch at location 4.
The diagram below shows a pond and how it changes over four weeks. Which conclusion BEST describes the pond during the four weeks?
Liquid water in a pond can change into a gas, but not a solid.
Liquid water in a pond can change into a solid, but not a gas.
Liquid water in a pond cannot be changed into a different state.
Liquid water in a pond can change into a solid or a gas.
Al thinks different-sized balloons make different forces as they let out air. How can he BEST plan an experiment to test this variable?
Let the air out of different-sized balloons to see which empties faster.
Propel the same toy car over the same surface with the air from same-sized balloons.
Propel the same toy car over the same surface with the air from different-sized balloons.
Propel different-sized toy cars over the same surface with the air from different-sized balloons.
