Using Density to Predict Planetary Differentiation part of Earth and Space Science:Summer 2011:Activities
This is an inquiry based lesson designed for middle school students (7th grade) who are already familiar with states and properties of matter. This lesson serves as an informal assessment of students' understanding of density, elements and also serves as an introduction to planetary formation. In this lesson, in lab groups, students determine how to measure and calculate the density of 3 different materials. Once the densities are calculated, students should apply what they know about density in order to make predictions of how these materials would differentiate during a planet's formation.
