Virtual Labs

Virtual Labs
The links on this page are all VIRTUAL LABS offered by the Glencoe textbook company. 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!

Cascades Volcano Observatory Why Study Cascade Volcanoes? Cascade Range Active volcanoes dominate the skyline of the Pacific Northwest. The familiar snow-clad peaks of the Cascade Range are part of a 1,300 km (800 mi) chain of volcanoes, which extends from northern California to southern British Columbia. The volcanoes are the result of the slow slide of dense oceanic crust as it sinks beneath North America (subduction), which releases water and melts overlying rock.

Inquiry and Integration Across the Curriculum Every time we open the local newspaper, listen to the evening news, or visit our favorite national online news source, we’re confronted with stories that directly or indirectly tell us something about the state of the planet. Whether it’s a debate about zoning ordinances for construction in wetland areas, the line item for fossil fuels costs in the annual school budget, local industrial soil contamination, or the price of gasoline at the pump, issues of environmental sustainability permeate our lives. Exploring the impact of human activity on the environment provides high school students with an opportunity to understand these issues from the inside out.

In my last geology hike to the trail, I took a photo of the great sedimentary layers at the north end of the trail, then edited the photo to show how well the strata line up on each side of a fault through the sediments. Mouse over the image below to see the image of the current conditions of the strata. Imagine the strata lined up like this years ago. The red arrow shows the relative motion of the rocks between "then" and now. Hover your mouse over the image to see the current condition of the strata.

A Hanging Rod — Collection of Solved Problems We will compare the mechanical energy of the rod in the situation (1) in which the rod still hangs vertically down and we have just given its end speed v. The second situation (2) will be in the moment when the rod reaches the horizontal position and its speed equals zero. We choose the zero level of the potential energy in the middle of the rod. In situation (1) the rod has a zero level of potential energy. Its kinetic energy equals: Geologic Hazards Some volcanic eruptions are mild and slow, while others are powerful and dramatic. An eruption happens when magma, gases, or steam break through vents in the Earth's surface. A mild eruption may simply discharge steam and other gases, or quietly extrude lava. A strong eruption can consist of violent explosions that send great clouds of gas-laden debris into the atmosphere, or may consist of explosions that blast sideways from a collapsed portion of the volcano, as happened in the 1980 eruption of Mount St. Helens.

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. Which Came First on Earth The hunt for life on other planets is due for a makeover. Although it is often confined to planets orbiting in the so-called habitable zone where proximity to their host stars makes temperatures just right for liquid water, many astronomers are beginning to think outside the “Goldilocks” box. Some wonder if previously overlooked mechanisms—including life itself—could broaden the habitable zone well beyond its current definition.
