Amir, Ethan, Aubrey, Alivia, and Anthony, a group of fifth graders, built a complete circuit to create a noise with a buzzer for their science project. After building the circuit, they noticed that the buzzer does not buzz. Why doesn't the buzzer work in their circuit?

• Amir and Ethan connected the wires incorrectly.

• Alivia and Anthony connected the buzzer incorrectly.

• Aubrey forgot to close the switch to complete the circuit.

• They need more batteries to make their circuit complete.

Anthony and Ethan are working on a science project where they use a heat lamp in a terrarium to create a warm environment for their pet lizard, F. What types of energy are present when the heat lamp is on?

• light, sound, mechanical

• electrical, light, thermal

• sound, thermal, electrical

• thermal, light, sound
