Gravimetric Soil Moisture Protocols
The purpose of this resource is to measure soil water content by mass. Students collect soil samples with a trowel or auger and weigh them, dry them, and then weigh them again. The soil water content is determined by calculating the difference between the wet sample mass and the dry sample mass.

Soil Particle Density Protocol
The purpose of this resource is to measure the soil particle density of each horizon in a soil profile. Students weigh a sample of dry, sieved soil from a horizon, mix it with distilled water and then boil the mixture to remove any air. The mixture cools for a day and then students add water until the volume of the mixture is 100 mL. Students measure the temperature and mass of the final mixture and use the Soil Particle Density Data Sheet to calculate the soil particle density. Three samples sh

GEOLogic: The Big Five Mass Extinctions
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match up the five largest mass extinction events with their relative dates, approximate duration, and severity (percentage of species that became extinct) based on clues given from various perspectives. This activity is appropriate for a high school science class or an introdu

Continental Crust Mass Balance Calculation
This problem set is designed for a junior/senior level course and addresses several quantitative skills that are important in geochemistry and petrology. The exercise uses geochemical data for average quartz monzonite and diorite from the Mineral Mountains in Utah. The students do mass balance calculations and are asked to relate their calculations to continental crust formation. The activity was peer reviewed by participants at the 2004 Teaching Quantitative Skills in a Geoscience Context Works

Inelastic Collision of Particles with Structure Model
The EJS Inelastic Collision of Particles with Structure model displays the inelastic collision between two equal "particles" with structure on a smooth horizontal surface. Each particle has two microscopic elements which interact through a massless spring of stiffness k and natural length L. The mass of one of the microscopic elements and the spring length of the connector spring can be changed via textboxes. You can modify this simulation if you have EJS installed by right-clicking within the p
