Since we were talking about Hoover Dam as our geography landmark, we spent a lot of time talking about forces of nature and how we feel them and use them. We tried to build a dam in our water and sand table without much success, but Anna also had two field trips that helped her see some of the things we were talking about in action. She has visited Palo Alto Junior Museum that went “whoosh” over her head. All she could tell me afterwards is that she saw machines and they give us energy. My husband said that the museum is not really suited for preschoolers, and the zoo that also belongs to it was overcrowded. She was a lot more interested in interactive exhibits of Children’s Museum of San Jose. Waterways is an amazing exhibit showing the power of both water and wind. There is also an interesting permanent exhibit called Power of Circles. That’s when Anna could operate a real pulley – she wanted to do it so badly after watching Sid the Science Kid episode about a pulley probably 10 times or more. She could also see how it’s much easier to pull heavy load on wheels and compare it to trying to push the same load along on the wooden floor. My favorite exhibit was a vertical blowhole that supported several light balls dancing in the air – it was fun to throw balls into it and seeing how the gravity seems to have no effect, cancelled by the power of wind.
