Light bulbs


One of the things I like about zoos is how the good ones blend education with entertainment and reach people who would not otherwise be exposed to information. In this case, as part of education around climate change, children are shown incandescent, compact fluorescent, and LED light bulbs. Energy efficiency is explained and kids are asked to guess which bulb would be least efficient and, therefore, hotter.

The kids seemed to be better guessers than the adults.
