How Long Will It Last?

Students turn on a flashlight and leave it on until the energy is used up (12-36) hours. They estimate or preduct how long they think the energy in the batteries will last. They then estimate how long a birthday candle will burn, giving off heat and light energy to relate the idea that energy will only last a certain length of time.

Your site is extremely easy to maneuver, and your search engine sorts beautifully--down to the grade level and super-specific subject matter. As a graduate student, studying for my teacher's license, I've found great, creative inspiration in the content links on your site. I count on your site more than any other I've found to date.
