How big is the solar system?


Yesterday Luke and I drew a scale model of the solar system on the driveway - the distances of the planets from the sun is proportional, and the size of the planets to each other is proportional, but the distances and sizes are not in scale. It was a lot of fun to do, and Luke is good an using the measuring tape and accurately identifying feet and inches.

Through the summer we're doing an integrated math/science unit published by NCTM and NASA for early elementary. Cool projects, easy to make accessible for his age. On Saturday we'll work on measurement and data analysis by flying paper airplanes.....what's not to like about that?
