Astronomy!











This winter we studied astronomy, and here is a picture of the balloon/small ball solar system model that has been hanging across our living room ceiling for the past few months. It was pretty easy to make-- Saturn was made by blowing up one of those extra long balloons and curving it around a regular balloon, attached with tape. All the balloons/balls were hung from thread and attached to the ceiling with pushpins. The dimensions were approximately to scale, except for being much closer together than in the scale of the real solar system, and Jupiter and Saturn needed to be bigger-- probably using a large punch ball would have been better for each of these planets. There was a handy list of approximate sizes to make each ball/balloon in the book we were using, Exploring Creation With Astronomy, by Jeannie Fullbright. We used a couple of small balls for the smallest planets--Mercury and Mars, and a large bead for Pluto.
