And the kindergarteners were so cute coming through. They just vibrated every aisle they went down. They got a huge kick out of everything that was here. That was great to see because that's what it's all about. |
It's fun math that gets them thinking. |
There's a lot of energy in here tonight. |
There's also a nice demonstration where they compared incandescent and fluorescent light bulbs in terms of heat generation and energy usage. And there were two comparisons of batteries and they both came out with the same results. I thought that was interesting. |
