Anatomy | The Biology Corner This worksheet provides steps for identifying structures of the grasshopper, with a focus on the external anatomy and mouthparts. The lesson can be part of a larger unit on insects … In animals, form and function are closely related. This concept is illustrated very simply by looking at a variety of bird species where the shape of the beak and … Instructions include how to identify crayfish mouthparts, eyes, and appendages. Students can follow up with a dissection to reveal the internal anatomy. Students investigate what happens to the respiration rate of a fish as the temperature is increased and decreased; includes directions, data table and analysis. Students examine the symptoms of a newborn baby who has a problem with his heart and suggest treatment options. Worksheet provides instructions for dissecting an earthworm, starting with external anatomy and then locating internal structures, like the crop and gizzard.
We’ve destroyed one-tenth of Earth’s wilderness in just 2 decades | Science | AAAS Similar estimates in the past have focused on deforestation, but the new study looks at the disappearance of a broader range of wild landscapes. “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. Watson, a conservation biogeographer at the Wildlife Conservation Society based at the University of Queensland, St. Wilderness is defined as pristine landscapes mostly free of human disturbances, including roads. By 2009, about 23% of Earth’s land remained as wilderness—about 30.1 million square kilometers spread mostly across North America, North Asia, North Africa, and Australia, they conclude today in Current Biology.
Molecular Workbench - An Interface to the Molecular World Zygote Body - Interactive Human Body Browser for your Whiteboard Biologists who wanted a human body browser in the same style as Google Earth, Google Sky, Google Moon etc got very excited a few years ago when Google brought out its Body Browser. They then got sad when Google retired it. Well it looks like it’s back (sort of) under new management and is now called Zygote Body. But it looks exactly the same as it did when it was Google Body, which is great. Zygote Body gives you a fully-explorable 3D body. You can move about, zoom in, like you can in Google Earth. Double click on any organ to isolate it from the rest of the body. This will make teaching about the human body much better on an interactive whiteboard. Combine this with the desktop annotation or image capture and annotate to label organs and systems, or to just explore different organs in detail. Hopefully this will be around for a while and won’t vanish like the Google Body Browser did. Go take a look at : www.zygotebody.com
Simulated global temperature change This animated spiral portrays the simulated changes in the global averaged monthly air temperature from 1850 through 2100 relative to the 1850 - 1900 average. The temperature data are from Community Climate System (CCSM4) global climate model maintained by the National Center for Atmospheric Research. The simulation is for the IPCC Representative Concentration Pathway 8.5 (RCP8.5) emission scenario. RCP8.5 is the most aggressive scenario in which green house gases continue to rise unchecked through the end of the century, leading to an equivalent of about 1370 ppm CO2, which is roughly four times the concentration at present. The CCSM4 simulation is part of the 5th Climate Model Intercomparison Program (CMIP5) and the data can be downloaded at The 21st century animations are an extension of the graphic ( for the 1850-2010 observed air temperature created by E.

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. 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. Student should be familiar with the following concepts before starting this lesson: The difference between climate and weather (3-ESS2-2) Respiration Photosynthesis Investigation 1: Part 1 Materials Preparation Background information for teacher
The Feynman Lectures on Physics Log In Video The Times’s Quentin Hardy talks with Mary Roach about her new book, “Gulp: Adventures on the Alimentary Canal.” Overview | In this lesson, students research the digestive system in depth, and then create a detailed walk-through model to illustrate each compartment.Materials | Computers with Internet access, projection equipment, an assortment of art supplies (butcher paper, fabric, yarn, cardboard, colored paper, tissue paper, paints, markers, glue, staplers, tape, scissors, etc.) Warm-up | When students arrive, project “Gulp! When you have finished, lead a short discussion to debrief the quiz. Did any of the answers surprise you? Ask students to think about why they may find this topic funny, gross or uncomfortable as you then play the video “The Inside Scoop on Your Insides.” When the video has finished, ask: Do you agree with the author Mary Roach’s assertion that “It’s uncomfortable for people to think about their insides at all?” What is the purpose of the study in which Ms.
ARKive - Discover the world's most endangered species Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, Arkive.org featured multi-media fact-files for more than 16,000 endangered species. Freely accessible to everyone, over half a million people every month, from over 200 countries, used Arkive to learn and discover the wonders of the natural world. Since 2013 Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. As a small conservation charity, Wildscreen eventually reached the point where it could no longer financially sustain the ongoing costs of keeping Arkive free and online or invest in its much needed development. Therefore, a very hard decision was made to take the www.arkive.org website offline in February 2019.
