Let there be light!
In our Exploring Physics class we continue to learn about stored chemical energy, atoms, and electrons. Our challenge this week was to use a C or D battery and a coated copper wire to light a light bulb. It is not as easy as it sounds!
The children worked in small teams of two or three, working together to brainstorm, test their ideas, and try again. Though several of the children felt confident in the beginning that they knew exactly what to do -- and they were close -- they actually worked for 45 minutes before the first team discovered exactly what they had to do to light the bulb.
