Active learning modules to help students understand the role of cover crop species selection and design of mixed species cover crop plantings on multiple ecosystem services. Our current goal is to integrate lessons-learned from 8 years of research and extension activities into undergraduate education modules that can be widely distributed. Students completing these modules would be able to describe why cover crops are used, how different species of cover crop affect an array of ecosystem functions, how mixtures can be used to increase the multifunctionality of cover cropping systems, and factors that control mixture growth across sites. If the modules are delivered in the following order then these concepts build sequentially.

This short video and interactive assessment activity is designed to give fifth graders an overview of comparing decimals.
This tool allows students to complete crossword puzzles on a variety of grade-appropriate topics, and also create and print their own crossword puzzles.
This exercise is based on the recent formulation of a geobarometer based on the crystal structure of clinopyroxene (Nimis, 1995; 1998; 1999). This method relates structural parameters (e.g., the volumes of the unit cell and the M1 polyhedron) to the pressure at which the mineral crystallizes within basic and ultrabasic magmas.
In this exercise, students are guided into the American Mineralogist Crystal Structure Database to retrieve and download published crystal structure data for viewing in either the CrystalMaker or XtalDraw visualization software packages. The students are instructed on how to examine the structures to determine pressure-sensitive crystallographic parameters and are asked a series of questions related to what they learn.

In this exercise, students use major-element compositions of whole-rocks, volcanic glasses, and minerals in lavas and drill cores from the solidified Kilauea Iki lava lake. The data is presented in the form of a "precompiled" spreadsheet which contains selected analyses culled from the GEOROC database and a USGS Open File report. Students make graphs from the data to learn about the petrologic processes related to the eruption and in situ crystallization of basaltic magma

Explore the relationship between the genetic code on the DNA strand and the resulting protein and rudimentary shape it forms. Through models of transcription and translation, you will discover this relationship and the resilience to mutations built into our genetic code. Start by exploring DNA's double helix with an interactive 3D model. Highlight base pairs, look at one or both strands, and turn hydrogen bonds on or off. Next, watch an animation of transcription, which creates RNA from DNA, and translation, which 'reads' the RNA codons to create a protein.
