In science class, children learn that planets orbit the sun. Building a model of the solar system, including the sun, eight planets and Pluto, reinforces this concept and provides children with a hands-on approach to learning the names and sequence of the planets. Depending on the age of t...
By fifth grade, students demonstrate knowledge of the solar system by naming the planets that revolve around the sun. Tomake a model of the solar system, they use different-size round objects for the planets and they create a ring for Saturn and multiple moons as well. Fifth-graders can cr...
Any model of the origin of the solar system must explain why all the planets orbit the Sun in the same direction and in nearly the same plane. One model that wasdevisedexplicitly to address this issue was the tidal hypothesis, proposed in the early 1900s.Two nearby planets, stars,...
