1. Consider the following question:

“A headlamp has one LED, takes three batteries, and has a switch that toggles between different circuit configurations. What circuit configuration will get the brightest light from the LED, and what configuration will provide the longest battery life? A different lamp has two LEDs, one battery, and a switch. Answer the same questions for this lamp.”

Attempt to answer this question and make note of what concepts are involved.

2. Using this question and the concepts you've come up with, create an experimental question and a hypothesis.
