Terrance set up this circuit with a battery, a switch, and light-emitting diode, or LED, lights. Which LEDs will produce light in this circuit?

• A. LEDs 1, 2, 3, and 4 will all produce light.

• B. LEDs 1, 2, and 4 will produce light.

• C. Only LED 3 will produce light.

• D. Only LED 1 will produce light.

Paulie builds a 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? Place each design in the correct category.

Groups:

(a) Meets the Criteria

,

(b) Does Not Meet the Criteria

• Design A

• Design D

• Design B

• Design C
