Conjugation & UV-Vis Spectroscopy: Crash Course Organic Chemistry #41
Read the Fine Print
Some Rights Reserved
Rating
0.0 stars

Carrots get their orange-y color from, you guessed it, an organic chemical. This chemical, called beta carotene, gets its pigment from its conjugated electron system. We’ve talked some already about conjugation, but in this episode of Crash Course Organic Chemistry we’ll go even deeper and look at how conjugation stabilizes molecules and how p orbitals can overlap to form pi molecular orbitals of different energy levels. Plus we’ll learn what UV spectroscopy can show us about conjugated molecules.

Consequences of Modern Energy Use: A Remote Sensing analysis of the gulf oil spill using ArcGIS software.
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

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.

Conserving Waterlogged Wood
Unrestricted Use
CC BY
Rating
0.0 stars

This video resource is presented as a real-world application of chemistry in the field of conservation archaeology. Conservator, Francis Lukezic, walks through the conservation practices for waterlogged archaeological wood and explains the chemical and cellular processes at work. Use to support Maryland/NGSS for Grades 5, MS, and HS. For 5-PS1-1 and MS-PS1-1, have students watch or perform the paper clip demonstration and discuss how the hydrogen bonding of water allows this then is disrupted by the soap; have students develop diagrams explaining the phenomenon of surface tension on the molecular level. For HS-PS2-6, have students watch or perform the sponge demonstration and discuss how the molecular structure of the wood makes it vulnerable to becoming waterlogged then brainstorm materials that are more resilient to water and discuss the uses of the materials. For interdisciplinary connections to geography and history, have students research why Maryland archaeologists do or do not discover the materials brainstormed instead of wood. If you evaluate or use this resource, please respond to this short (4 question) survey bit.ly/3DhRumA

Constraints and Implications of Groundwater Temperature on the Formation of Mississippi Valley-type Zn-Pb Deposits
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

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.

Rating
0.0 stars

This homework assignment is designed to give the students practice in developing a simple conceptual model using reservoirs, fluxes, and simple calculations of sediment, carbon and nutrient accumulation in a typical reservoir/river system. This assignment is typically used after an introductory lecture to biogeochemical cycles and gives the students a concrete example of nutrient and sediment issues in surface water systems.

In this activity, students construct three-dimensional models from terrain information provided by two-dimensional topographic maps. This will allow them to visualize how changes in elevation over a certain distance can be represented on a flat piece of paper that can be folded up and tucked away. Each group is responsible for constructing a model of Mount St. Helens 'before' and 'after', a depression, a stream, and a hill. Discussion questions related to the different representations are also included.

Cosmic Origin of the Chemical Elements
Conditional Remix & Share Permitted

Rating
0.0 stars

Everything around us is made from different chemical elements: carbon, silicon, iron, and all the other elements from the Periodic Table. The lighter elements were mostly produced in the Big Bang, but the rest were (and are) formed within stars and in the explosions of supernovae. In this series of short lecture videos, created to accompany her book Searching for the Oldest Stars: Ancient Relics from the Early Universe (Princeton University Press, 2019), Professor Anna Frebel reveals the secrets of stardust and explains the cosmic origin of the elements.

Counting Atoms: How Not to Break the Law of Conservation of Matter

Educational Use
Rating
0.0 stars

Students explore the science of microbial fuel cells (MFCs) by using a molecular modeling set to model the processes of photosynthesis and cellular respiration—building on the concept of MFCs that they learned in the associated lesson, “Photosynthesis and Cellular Respiration at the Atomic Level.” Students demonstrate the law of conservation of matter by counting atoms in the molecular modeling set. They also re-engineer a new molecular model from which to further gain an understanding of these concepts.
