These labs give the students the adventure of laboratory experimentation without costly supplies, worrisome environmental and safety issues, or time-consuming clean up. They are from all different areas of science: Biology, Physics, Genetics, Earth Science, Physical Science, and Chemistry. Please feel free to try these at home! Students will be directed to specific labs in class but there are over 100 labs offered here! To return to the home page, please click here:

His ghosts were of the meandering Mississippi. A river, big or small, doesn’t stay still – as its waters flow it carves out new paths in a route towards its ultimate destination. 60 questions total Earth and Environmental Science Summative Assessment 54 questions Objectives Tested: 1.02, 1.06, 2.05, 2.01, 6.01, 6.02, 2.03, 2.06, 2.02, 2.04, 3.01, 2.07, 4.02, 5.01, 5.03 1.

River Systems: Process and Form Compiled by Jeff Crabaugh at Carleton College (more info) (SERC) and the University of Wyoming This section provides access to a number of visualizations and supporting material that can be used effectively to teach students about physical processes acting in rivers and their floodplains. Visualizations include simple animations, visual output from numerical models, as well as numerous static illustrations and photos. For more visual resources, browse the complete set of Visualization Collections. Rivers DETERMINING AGE OF ROCKS AND FOSSILS THE AGE of fossils intrigues almost everyone. Students not only want to know how old a fossil is, but they want to know how that age was determined. Some very straightforward principles are used to determine the age of fossils. Students should be able to understand the principles and have that as a background so that age determinations by paleontologists and geologists don't seem like black magic. There are two types of age determinations.

NWS JetStream Learning Lesson: Water Cycle Paper Craft Overview Water moves from the ground to the atmosphere and then returns to the ground, however, the actual path water takes in its cycle is more complicated. There are many stops on water's journey. Students will learn how the water cycle works using 3-D paper craft activity. Nature & Science» Geology Resources Division Since each of Grand Canyon’s three sets of rocks is unique, different dating techniques were used to determine the age of rocks in each set. Radiometric dating techniques revealed the absolute age of the igneous and metamorphic rocks of the Vishnu Basement Rocks, and also provided dates on volcanic ash beds and other datable units in the mostly sedimentary Grand Canyon Supergroup. Relative dating, index fossils, and geologic correlation were used to determine the geologic age of the Layered Paleozoic Rocks, and numeric ages were then inferred. A wide variety of numeric ages for Grand Canyon rocks, particularly for the sedimentary rocks which usually cannot be absolutely dated, exist in both the technical and popular literature. When someone’s objective is really just to learn how long ago these rocks formed, it is very confusing to sort through subdivisions of geologic periods, the scientific names of microscopic index fossils, and the nuances of radiometric dating techniques.

Triple Divide Peak, Montana - EPOD - a service of USRA Provided by: Tom Kotynski, Great Falls Tribune Summary authors & editors: Rod Benson The peaks shown in the above photo are glacial horns located in Glacier National Park, Montana. These pyramid-shaped features are formed as three or more glaciers erode the sides of a single mountain. The larger horn in the background is Mt.
