Monday, February 13, 2006 - Soap Boat Race
The kids carved boats out of Ivory soap and had a boat race in the bathtub. Kaden's sail caused his to tip over so we had to remove the sail for the race. He ended up winning by about 4 inches. Katibree screamed in retaliation.
Kaden used 3 bars of soap before he got it just right. The first two ended up breaking because he couldn't determine a good whittle-stopping point before it was too late. Once I showed Katibree how to whittle a little at a time instead of trying to get a big chunk off at one time, she really did a good job. Kaden had more fun making the sail or mast than the actual boat I think.
Also, we had fun talking about friction today, especially with the great examples provided by the Olympic games (Aero-dynamic everything to reduce friction). We froze a sheet pan of water to see if his hot-wheel car would be able to roll across it. We raced cars on different textured surfaces. Then the kids made up their own ice skating event with GI Joes on the sheet of ice. As the ice melted, they added ice cubes...and pretty soon it was a war zone complete with bunkers...it entertained them for about an hour.
In math today, Kaden did a worksheet of addition doubles (1+1, 2+2...) in random order. He got all 25 right and did it in 2 1/2 minutes. Math is definitely his thing.
