anita and tomás are trying to determine what decreases lightbu
test 1
test
which choice best identifies the students next testable question?
○ what is the effect of adding a fan to both circuits?
○ what is the effect of adding another bulb to the circuit?
○ what is the effect of adding one more battery to both circuits?
○ what is the effect of adding a different type of wire to both circ

Explanation:

The students are investigating factors affecting lightbulb brightness in circuits. A testable question should relate to circuit components (bulbs, batteries, wires, etc.). Adding another bulb (option about adding another bulb) is a direct extension of their current circuit study (Test 1 has one bulb, testing another bulb’s effect is logical). Other options: fan is unrelated to circuit/lightbulb brightness; different wire or battery addition is less direct to the initial focus on bulb count/arrangement.

Answer:

What is the effect of adding another bulb to the circuit?
