In this activity, students will explore the concepts of Heliocentric and Geocentric models by conducting a marble rolling experiment. Jenna investigates whether a large glass marble rolls further than a small one, repeating her trials multiple times. After recording her data, students will analyze the results to identify correct statements about the rolling distances of both marbles. This hands-on approach promotes understanding of scientific inquiry and data interpretation, reinforcing key astronomical concepts.

Objective: • Bell Ringer 71 • Sampler 2011 #1 • Understand the difference between the Heliocentric and Geocentric models.
Jenna rolled a small glass marble and a large glass marble down a ramp at the same time to see if the large marble would roll further than the small one. She repeated this investigation four times. These are her results.
Which of the following statements is true? A. The small marble rolled further than the large marble in trials 2 and 3. B. The large marble rolled further than the small marble in trials 1 and 4. C. The difference in distances rolled by the small marble is less than 8 cm. D. The difference in distances rolled by the large marble is less than 8 cm.
