ID Code: E2-36
Purpose: Demonstrates how density stratification (differentiation) in interior of planets occurs.
Description: Heavy balls represent dense material (e. g., iron or nickel). Light balls represent light material (e. g., silicates). Use wooden plank to vigorously mix the balls, then remove the plank and watch heavy balls settle. Mixing simulates the hot molten interior of a young planet. Settling simulates differentiation in molten interior of an older planet.
