This 90-minute activity features six interactive molecular models to explore the relationships among voltage, current, and resistance. Students start at the atomic level to explore how voltage and resistance affect the flow of electrons. Next, they use a model to investigate how temperature can affect conductivity and resistivity. Finally, they explore how electricity can be converted to other forms of energy. The activity was developed for introductory physics courses, but the first half could be appropriate for physical science and Physics First. The formula for Ohm's Law is introduced, but calculations are not required.

This concept-building activity contains a set of sequenced simulations for investigating how atoms can be excited to give off radiation (photons). Students explore 3-dimensional models to learn about the nature of photons as "wave packets" of light, how photons are emitted, and the connection between an atom's electron configuration and how it absorbs light. Registered users are able to use free data capture tools to take snapshots, drag thumbnails, and submit responses.

This laboratory activity takes place in a computer lab that is equipped with ArcGIS (we are currently using ArcGIS 9.3). Students will go to NASA's oil spill gallery website and download the full size image of the Deepwater Horizon oil slick from July 14th, 2010 taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite at 1:55 p.m. Central Daylight Time. Their task is to to analyze the satellite imagery as an RGB composite and to experiment with reclassification techniques to subdivide the continuous raster dataset into user-defined numbers of ranges that will help visualize the oil spill. The activity introduces students to GIS software, remote sensing analysis, and sets up questions on spatial patterns and consequences of energy use.

This assignment is meant to illustrate how the advection of heat by groundwater leads to the elevated temperatures at shallow sedimentary basin margins at which Mississippi Valley-type Zn-Pb hydrothermal ore deposits are formed. The assignment is based on analytical solutions for groundwater flow and heat transport published by Domenico & Palciauskas (1973). Students use a spreadsheet to calculate and plot the flow field and temperature in a sedimentary basin, and to investigate the conditions needed to produce ore-forming temperatures. These results have further implications for the length of time available for ore formation and the concentration of metals and pH of the groundwater, which are also explored in the assignment. The assignment provides an example of how groundwater plays a fundamental role in an important geologic process in the Earth's crust. The activity also shows the linkages of hydrology to other disciplines such as heat transport, geochemistry, and economic geology.

This lab is divided into two exercises that may be completed within a single three-hour session. The first exercise requires the mixture of aqueous solutions that will precipitate large euhedral crystals over the course of 1 to 2 weeks. These experiments are intended to mimic the slow growth of macroscopic minerals in thermal and chemical equilibrium. In the second exercise, students observe rapid growth of dendritic crystals in strongly undercooled solutions in order to visualize the disequilibrium growth processes that occur in the atmosphere, at chilled margins, and in highly supersaturated solutions.

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.
