This American Museum of Natural History press release, issued in April 2001, announces the discovery of a remarkably well-preserved, 130-million-year-old fossil dinosaur covered from head to tail with downy fluff and primitive feathers. The press release includes details about where the dinosaur was unearthed, and by whom, the significance of the finding, the geologic reasons why the area where this specimen was found has been a treasure trove of fossils and how dinosaurs are related to birds.

This project will be focused on designing, constructing and evaluating different containers to determine the optimal design for heat retention. After students have constructed their designs and collected and shared data, students will evaluate the class data to create an optimal design for our culminating event: warming ooey, gooey chocolate chip cookies to perfection! Through this activity, students will learn about energy transfer, engineering design process, data collection, graphing, rate of change, optimization, surface area and proportions. The students will test the effectiveness of their design using Vernier Probes to gather quantitative data and graphing the rate of temperature change. They will then create a poster presentation to share their data to the class. Students will use their mathematical skills to quantitatively analyze the strength and weaknesses of their designs while enjoying some delicious, toasty, warm cookies.

This reference includes individual titles of note along with the most popular field guide series. For each guide, the author, publisher, and publication date are given. The diverse list has 17 individual titles, which cover everything from wildflowers in the Colorado mountains and insects north of Mexico to the natural history of vacant lots. There are detailed descriptions of four of the most popular field guide series: Audubon Society Guides, Golden Guides, Peterson Guides, and Stokes Nature Guide Series.

This is a 21 day unit on the topic of floods. Students will plan and prepare for what might happen in the event of a flood in our area. We have had floods in the past that have affected the Walterville School, its campus, and the surrounding areas. Using this as a springboard, students will discuss the effects of flooding, do research and interview family members who have experienced flooding, and then discuss possible ways to prevent significant damage on the buildings and surrounding areas. They will then design a barrier that could protect an area from damage for a period of time. Students will need materials to conduct experiments. We have listed these in the lesson plan. We have also included a trip to the Leaburg Dam so that students can learn about dams and their uses. We plan on teaching this unit in the fall.

The purpose of the exercise is to familiarize igneous petrology students with flow properties of lava, especially viscosity, and to have them consider effects on viscosity due to temperature, crystallinity and volatile content. The problem uses data from an actual eruption.

This document aims to reduce the guesswork of in-camera focus bracketing with the OM SYSTEM OM-1 and 60mm F2.8 Macro. It includes hand-calculated data which identifies aperture (F-Stop) and focus differential (FD) to produce image series with appropriate focus overlap and no banding.

About 4.6 billion years ago, a cloud of interstellar dust, ice crystals, and gas collapsed to form a rapidly rotating disk with a young sun at its center: our solar system. This comic strip, a supplement to the Hall of Meteorites Educator's Guide, explains the processes that led to the creation of the planets and the asteroid belt.

The freely accessible moodle platform offers a number of insights into past proejct work as well as a documentation of the results that were achieved in the course of the project.

The Gamma-ray Burst Skymap website automatically updates for each gamma-ray burst as it occurs, whether detected by Swift or other orbiting satellites. For each burst, the location on the sky, star map, constellation and detecting mission are generated automatically. It is then quickly updated by hand to include a written description of the burst properties and scientific significance, as observations continue. Note: In order to view the content of the website, users need to download and install Silverlight on their computers.

In this activity, students study gas laws at a molecular level. They vary the volume of a container at constant temperature to see how pressure changes (Boyle's Law), change the temperature of a container at constant pressure to see how the volume changes with temperature (Charles’s Law), and experiment with heating a gas in a closed container to discover how pressure changes with temperature (Gay Lussac's Law). They also discover the relationship between the number of gas molecules and gas volume (Avogadro's Law). Finally, students use their knowledge of gas laws to model a heated soda can collapsing as it is plunged into ice water.

The January 2012 issue of PLOS Neglected Tropical Diseases presented an Editorial, a Viewpoint, and two accompanying Expert Commentaries that focussed on the application of genetically modified (GM) insects for control of animal and plant diseases. These articles describe the technological advances these tools represent, the regulatory framework, and the societal dialogue that is necessary for their wide-scale application for disease control. Here, we have assembled a collection of articles published in the PLOS journals that describe the technical and applied aspects of GM insects. We also included articles that are not strictly GM, but aim to modify the disease transmission traits of insects through the use of symbiotic microbes.

The Geniverse software is being developed as part of a five-year research project funded by the National Science Foundation. Still in its early stages, a Beta version of the software is currently being piloted in six schools throughout New England. We invite you to try the current Beta version, keeping in mind that you may encounter errors or pages that are not fully functional. If you encounter any problem, it may help to refresh or reload the web page.

Students learn about the variables governing the brittle and ductile behavior of rocks, the simple geological structures associated with differential stress, and look at and apply real data to evaluate the depth to the brittle-ductile transition in the crust and how that depth can change temporarily due to sudden changes in stress introduced by large earthquakes.

In this problem set the students use two different equations to calculate a conductive geothermal gradient using a spreadsheet program like Excel. Once they have the geothermal gradient plotted, they are asked to experiment with and comment on the model by changing parameters (e.g. mantle heat flow, thermal conductivity). There is a mix of specific, fill in the blank questions and open-ended questions. This problem set helps develop quantitative problem solving skills using a spreadsheet as a tool, and forces students to think about thermal constraints during igneous and metamorphic processes.

Geological processes at the mid-ocean ridges are responsible for the bulk of the Earth's heat loss and volcanic activity. The compositions of materials erupted at these locations, dominantly mid-ocean ridge basalts (MORB's), have profound implications for the inner workings of the Earth's mantle, the construction of oceanic crust, and global plate tectonics. In this exercise, students replicate a portion of a classic paper on MORB geochemistry [Klein and Langmuir, 1987] , but using a much larger global geochemical dataset downloaded from the PETDB database. Through a series of activities and questions, students are encouraged to think about the petrologic and geodynamic processes controlling the composition of Earth's most abundant volcanic rocks.

This lesson examines the effects of surface energy transfer and storage on ocean temperatures. Included are activities that introduce the use of scientific models. Students then use an energy flow computer model to track energy changes by manipulating four variables: solar energy, heat transfer, water transparency, and seasons of the year. Note that this is lesson four of five on the Ocean Motion website. Each lesson investigates ocean surface circulation using satellite and model data and can be done independently. See Related URL's for links to the Ocean Motion Website that provide science background information, data resources, teacher material, student guides and a lesson matrix.
