Today we headed to our favorite science museum to see their new exhibits. The boys always love seeing the familiar, but definitely love exploring the new. The water cycle exhibit was pretty cool. They could see where rain goes - from your roof to the water treatment plant.
We saw how much water weighed, and how far many people on the planet must carry their water every day. We read how much water people use in this country daily (ouch). We compared showerheads for water usage. We saw how plants and fish work together in aquaponics to filter and grow in a beneficial dependency.
We walked through a green built house and compared different types of insulation, paints, flooring, and windows. We looked at different light bulbs, read about fiber optic solar, and saw how much electricity a live eel was generating in a tank (cool!). The boys even got to run and produce kinetic energy...by running in what really was a gigantic hamster (uh, human) wheel. They lit up light bulbs running and running.
We explored wind turbines, hydrogen cells, nuclear power, solar power...they felt good about how much they already knew, and excited to find out more about a few new interesting things (electric eels).
A nice break from our intensive gardening efforts of the past month or so. Tomorrow more rain - the boys won't mind though, as we have a new fun game...Earthopoly...and we have some research to do on those electric eels!
