Fred has a very detailed model of the solar system where each planet is made out of granite rock. Since his little sister really liked the model, he spent two weeks in his dad's workshop building her a Styrofoam copy. When he picked up the models to take them back inside the house, which physical property would he immediately notice upon picking them up?

Since color can be noticed without picking either model up, the answer would be density. This is definitely evident because Styrofoam is less dense than granite.
