The resources are divided into four parts that are structured around the lab process. PreLab: An opportunity to actually understand what the lab is all about before it starts. InLab: How to set up an experiment, take notes on protocol and instrumentation, organize and record data, and how to display data in meaningful tables and graphs. Useful information and resources including graphing aids, examples of lab reports that illustrate how the parts of the report are written and arranged, and a glossary of terms such as control, precision, and accuracy. PostLab: Offers a systematic approach for reflecting, organizing, and communicating the relationship between ideas and the evidence collected. PostLab brings the PreLab and InLab experiences together to help stuidents, step by step, create a complete and effective lab report. LabCheck: Finally, in the LabCheck section, LabWrite gives students an opportunity to review the work. LabCheck can also help students interpret their grade. LabWrite is based on a "backwards" approach to writing a lab report. http://www.merlot.org/merlot/viewMaterial.htm?id=89792 An interactive educational tutorial designed to provide information on atomic structure. This tutorial includes animations and simulations, discussion boards, interactive quizzes and is available in both English and Spanish. http://www.merlot.org/merlot/viewMaterial.htm?id=83558 Students follow the evolution of chemiosmosis and the role it played in the evolution of cellular life. Students will: 1) learn about chemical and cellular changes on early earth; 2) analyze efficiency of early forms of chemiosmosis; 3) compare mechanisms of non- and oxygenic photosynthesis, and 4) evaluate metabolic advantages of several endosymbiotic relationships. http://www.merlot.org/merlot/viewMaterial.htm?id=83564 Students compare the energetics of photosynthesis, cellular respiration, and cellular work. Students will: 1) complete a review table that summarizes the energy inputs, outputs, free energy change, etc. of these processes; and 2) review free energy change, Gibbs free energy, enzyme involvement, energy input and output. http://www.merlot.org/merlot/viewMaterial.htm?id=266078 Text and quicktime tutorials on how to do and use dilutions, including calculations, serial dilutions, how to make solutions, and sample problems. http://www.merlot.org/merlot/viewMaterial.htm?id=80974 This site has a lot of text materials covering many general chemistry topics. Some categories included on this site are the following: Numbers and Math, Units and Measures, Atomic Structure, Elements, Periodic Table, States of Matter, Compounds, Reactions, Mols, Oxidation and Reduction Reactions, Gases, Solutions, Acids and Bases, Kinetics (coming soon), and Thermochemistry (coming soon). http://www.merlot.org/merlot/viewMaterial.htm?id=83561 Students follow energy conversions in Euglena, during photosynthesis, respiration, and cellular work. Students will: 1) review definitions and properties of endergonic and exergonic processes; 2) explain, in qualitative terms, free energy changes in the universe, photosynthesis, respiration and cell work; and 3) identify the type of work (chemical, mechanical, etc.) being done in a number of cellular processes. http://www.merlot.org/merlot/viewMaterial.htm?id=79568 This Chime tutorial provides a detailed exploration of the structure of the molecule, insulin and the specific examination of alpha helices and disulfide bonds. The authors provide a worksheet of questions that visitors can use to fully explore the molecule. http://www.merlot.org/merlot/viewMaterial.htm?id=266089 Six flash animations that show the data collection, graphing and calculations commonly done in an enzyme kinetic assay for simple Michaelis-Menten and LineWeaver-Burke determinations of Km and Vmax http://www.merlot.org/merlot/viewMaterial.htm?id=694508 This is an interactive tutorial presenting proton NMR for students in a university level introductory organic chemistry course. It consists of four components: - Theory, Correlation Table, Virtual Lab, and a Quiz. In the latter students build a spectrum by dragging and dropping signals from a "peak pool" onto a baseline.
