This is a laboratory investigation where students will use the scientific method to solve a new, experimental question in chromatography.
The 'A Civil Action' 1-D Contaminant Transport Game is an EXCEL spreadsheet that enables students to compute concentrations of TCE traveling in the groundwater flow system toward well H that emanate from the W.R. Grace site. The idea of the game is to draw students into learning some of the fundamental concepts about (1) how contaminants move in the subsurface and (2) how models can be used to test hypotheses. These concepts are taught within the context of the famous 'A Civil Action' trial described in the book by Jonathan Harr (1996) and the movie starring John Travolta (1998).
The spreadsheet computes values of hydraulic head, advective flow velocities and traveltimes, contaminant velocities, and contaminant concentrations at 20 locations along the flowpath from W.R. Grace to the Aberjona River. Breakthrough curves showing changes in concentration versus distance and changes in concentration versus time pop-up automatically (see below). The spreadsheet also creates graphs of advective and contaminant velocities versus distance.

An infograph on Classification of Chromatographic Methods.
The topic is 'Classification of Chromatography'. Powerpoint application has been used for making the infographic. It briefly explains what is chromatography and its various types.
The illustration contains explaination of all classifcation of the chromatographic methods. And this illustration also contains the informations about different types of chromatogrpahy with the explaination of mobile and stationary phases. I have made this illustration using 'Microsoft Power Point Presentations'.And I have added the refernces sources and name at the bottom of the page.
This infograph gives you the detailed information on classification of chromatographic methods. Chromatographic methods had 3 main types that is based on stationary, stationary phase format & mobile phase.

This article continues an examination of each of the seven essential principles of climate literacy on which the online magazine Beyond Weather and the Water Cycle is structured. Principle 2 covers the complex interactions among the components of the Earth system. The author discusses the scientific concepts underlying the interactions and expands the discussion with diagrams, photos, and online resources.
This activity is designed to help students visualize and explain the relationships between various terms and concepts related to the science of climate change. After performing this activity students will (hopefully) be able to define various climate change terms and explain the process of climate change.

This unit introduces high school students to climate change, the carbon cycle, and the effects of increasing atmospheric carbon dioxide on Earth's climate. Students create a model from string, toss bean bags, and sort chemical cards to review key processes in the carbon cycle. Then they quantitatively model the carbon cycle by playing a board game.
This question is addressed through a series of questions and answers, each providing related introductory information such as how climate change is studied, the history of Earth’s climate, and the effects of climate change on Earth’s geology and biology. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.
Use the imbedded sliding scale to observe changes in sea ice distribution, carbon emission levels and average global temperatures over time, as well as the effects of variations in sea level rise along coastal regions. This interactive is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.
Students will study how temp and concentration affect reaction rates and then design a procedure to get the reaction to occur in a specified amount of time.
Polymers are a vital part of our everyday lives and nearly all consumer products have a plastic component of some variation. Students explore the basic characteristics of polymers through the introduction of two polymer categories: thermoplastics and thermosets. During teacher demos, students observe the unique behaviors of thermoplastics. The fundamentals of thermoset polymers are discussed, preparing them to conduct the associated activity in which they create their own thermoset materials and mechanically test them. At the conclusion of this lesson-activity pair, students understand the basics of thermoplastics and thermosets, which may entice their interest in polymer engineering.
Coalbed methane (CH4) is a natural gas and valuable energy resource that occurs in coal beds. This site, hosted by an energy development corporation, explains the geology and stratigraphy of Wyoming in the context of the formation of coalbed methane and its occurrence in Wyoming. Maps, cross sections, stratigraphic columns and fence diagrams are provided to explain Cretaceous and Tertiary coalbed methane-plays in Wyoming.
This interactive resource adapted from the National Park Service describes the different kinds of sediments that make up coastlines, with a focus on the variety in color, size, and sorting.
Climographs, graphic plots of monthly temperature and precipitation, allow students to see how differences in insolation at various locations affect rates of heating and cooling. In this activity, students use climographs to plot locations using latitude and longitude, calculate annual temperature ranges, and relate unequal rates of heating and cooling to climate variations. They will also construct climographs for two locations in New York, analyze them, and answer questions about their observations.
Based on the 2010 Scientific American paper by Hazen, and the more technical 2008 paper of Hazen et al, both of which explore the effect of the biosphere on the tremendous number of mineral species that occur on Earth compared to the lesser number we believe we are seeing on other planets. This tackles the idea of mineralogy/geochemistry evolving over time as do biological systems, rather than being a static system with no hysteresis or temporal aspect to it. Students work in small groups to decide which groups of minerals have been most affected by a variety of biological influences, and how. Then the class as a whole compares their conclusions group by group.
