This is a lesson about planet sizes. Learners will demonstrate the size (volume) differences between Earth, Earth’s Moon, and Mars. An extension to estimate the distance between the Earth and the Moon, and the Earth and Mars, using the scale of the play dough planets' sizes is provided. Advance preparation of the play dough (recipie provided) is required. This is lesson 3 of 16 in the MarsBots learning module.
