Catching the Wrong Species. This article in NSTA’s December 2014 issue of “The Science Teacher” describes a classroom activity that uses engineering design to help students model modern fishing gear to minimize bycatch in the tuna fishery.

Catching the Wrong Species

(Bycatch is non-targeted marine species typically caught in fishing gear). The lesson uses the 5E instructional model (Engage, Explore, Explain, Elaborate, Evaluate) and outlines a number of techniques to deepen student understanding of the concepts the model represents. The classroom model employs common household items (e.g., different types of beans, marbles, tennis balls, and buckets) to create a model of the ocean.

Geoinquiries. Wastewater treatment upgrades result in major reduction of intersex fish. Upgrades to a wastewater treatment plant along Ontario's Grand River led to a 70 per cent drop in fish that have both male and female characteristics within one year and a full recovery of the fish population within three years, according to researchers at the University of Waterloo.

Wastewater treatment upgrades result in major reduction of intersex fish

The 10-year study, published in Environmental Science and Technology found that the microorganisms used to remove ammonia in the wastewater treatment process also reduced the levels of endocrine disrupters in the water, which caused the intersex occurrences in fish to dramatically decline. "Having long-term data of the fish population, before and after the wastewater treatment upgrades makes this a truly unique study," said Mark Servos, Canada Research Chair in Water Quality Protection in Waterloo's Department of Biology. "The changes to Kitchener's wastewater treatment system have had a much larger positive impact then we had anticipated.

" Earth's 'technosphere' now weighs 30 trillion tons. An international team led by University of Leicester geologists has made the first estimate of the sheer size of the physical structure of the planet's technosphere -- suggesting that its mass approximates to an enormous 30 trillion tons.

Earth's 'technosphere' now weighs 30 trillion tons

The technosphere is comprised of all of the structures that humans have constructed to keep them alive on the planet -- from houses, factories and farms to computer systems, smartphones and CDs, to the waste in landfills and spoil heaps. In a new paper published in the journal The Anthropocene Review, Professors Jan Zalasiewicz, Mark Williams and Colin Waters from the University of Leicester Department of Geology led an international team suggesting that the bulk of the planet's technosphere is staggering in scale, with some 30 trillion tons representing a mass of more than 50 kilos for every square meter of Earth's surface. "Compared with the biosphere, though, it is remarkably poor at recycling its own materials, as our burgeoning landfill sites show. Ask the Weather Guys: Was all of autumn unusually warm? Q: Was the whole autumn unusually warm, or just November?

Ask the Weather Guys: Was all of autumn unusually warm?

A: If you thought November was warmer than usual around southern Wisconsin, you were exactly right. Madison averaged 7.6 degrees above normal for the month, which ranked as the third warmest November on record (since 1870). Our most detailed view of Earth across space and time. What Is Missing? Tst1608 32. Carbon dioxide levels race past troubling milestone. Every year, the amount of carbon dioxide (CO2) rises during winter and then falls slightly during the Northern Hemisphere’s growing season, as plants take up the greenhouse gas during photosynthesis.

Carbon dioxide levels race past troubling milestone

But this year, for the first time since before the Ice Age, CO2 will not fall below 400 ppm. “It’s unlikely we’ll ever see CO2 below 400 ppm during our lifetime and probably much longer,” says Pieter Tans, lead scientist of NOAA's Global Greenhouse Gas Reference Network. Measurements taken at NOAA’s atmospheric observatories on Mauna Loa and at the South Pole both indicate that CO2 has passed 400 ppm for good. What’s so important about 400 ppm? Four hundred parts per million is an arbitrary milestone, but it also may be a window on our future. ARKive - Discover the world's most endangered species. Lesson Plans.

Carbon Sequestration NGSS. Investigation 1 The Lesson Level Learning Goals for Investigation 1 are: Ask and answer questions to identify and clarify evidence that various activities can increase the carbon dioxide in the atmosphere and Analyze and interpret data to make a claim about a tree’s ability to store carbon.

Carbon Sequestration NGSS

Students will build towards this goal by engaging with different phenomena. First, students will figure out that plants absorb carbon dioxide from their environment by using an indicator tool to observe changes in carbon dioxide levels in a controlled environment. Next, they will be introduced to a tool that they will then apply to collect quantitative data from a subset of local trees to identify characteristics that affect a tree’s ability to store carbon. We’ve destroyed one-tenth of Earth’s wilderness in just 2 decades.

Similar estimates in the past have focused on deforestation, but the new study looks at the disappearance of a broader range of wild landscapes.

We’ve destroyed one-tenth of Earth’s wilderness in just 2 decades

“This is the first time that anyone has put a number on the loss,” says Tim Newbold, a conservation biologist at University College London whose own work has shown that wilderness areas contain the world’s most undisturbed biodiversity. Such unspoiled regions, scientists argue, are also critical for allowing the planet to cope with climate change. As a result, this new work is “a wake-up call,” says Robin Chazdon, an ecologist at the International Institute for Sustainability in Rio de Janeiro, Brazil, who was not involved with the study.

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.

Inquiry and Integration Across the Curriculum

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. By conducting hands-on research, teens will interact with their surrounding environment, collect evidence, and analyze results as well as the implications for their community. Essential Question: What is impact of human activity on the environment? Supporting Questions: How do scientists study the environment? 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! APES - Kessler Science.
