Describe the Earth as the third planet from the sun, eight other planets and their moons, and smaller objects, such as asteroids and comets. The Sun, an average star, is the central and largest body in the solar system. Given a problem statement, develop and test a hypothesis.
Some scientists work in teams, and some work alone, but all communicate extensively with others.
C. Divide the students into cooperative groups and ask them how they think the planets are spread out. Have each group determine a hypothesis to illustrate their suggested answer to the question. D. Give each group 4m of string, a roll of tape, and 10 strips of paper. Using the string, the strips of paper, and the given distances, make a model of the solar system. Measure 10cm for each AU and locate the position of each planet in relation to the sun.
