Soil Characterization Protocol
The purpose of this resource is to characterize the physical and chemical properties for each horizon in a soil profile. Students identify the horizons of a soil profile at a soil characterization site, then measure and record the top and bottom depth for each horizon. For each horizon, students describe the structure, color, consistence, texture, and abundance of roots, rocks, and carbonates. Samples are collected and prepared for additional laboratory analysis.

The Earth's Shells - Density vs. Depth
In this activity students devise a way of graphically plotting the density variations vs. depth in the Earth. They recreate spreadsheets, shown in the Powerpoint module, with formulas that answer various pieces of the overall question. This module is the sixth in a series of six that examine the density of planets and rocks, and was designed for an undergraduate class where students are asked to look at geological questions mathematically and may spend more time on the math than on the geology.

Exploring Radiometric Dating with Dice
In this lab, students use dice to simulate radioactive decay. Students create a standard decay curve for a fictional element, calculate the half-life of this element, and, using the information their graph, "date" rocks that contain the new element. The use of dice has some advantages over similar exercises because the half-life is not immediately obvious to students and they will need to experimentally determine it. Learning goals, context for use, teaching tips, materials, assessment tips and
