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.

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. “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. pwpt biology The Spider Silk Protein May Lead to Generation of Artificial Heart for HumansThe biocompatibility, biodegradability and strength of spider silk are some of the properties that have excited researchers on the possibilities it provides. This is a protein-based compound that does not cause any adverse allergic, immune or inflammatory reactions in humans. Recently, recombinant technology has enabled scientists to manufacture spider silk, and there is a race … Continue reading "pwpt biology"Researchers Literally Reach for the Moon in Search for Parkinson’s Disease CureResearchers believe that the cure for Parkinson’s disease may be found by conducting their experiments in microgravity environments in space. One of the key Parkinson’s Disease proteins, called LRRK2, will be sent to the International Space Station for further study.

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. 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.

Biology PowerPoints This page contains links to the PowerPoint presentations that I use in class. Though I place them here to give my students 24/7 access, they may also be used by any teacher or student who can benefit from this resource. Feel free to alert me to errors or problems you encounter with them. I am no longer posting these presentations in Flash. I have shifted completely to HTML 5 format, which means that these can now be viewed on mobile devices with HTML 5 enabled browsers, such as iPhones, iPads, and Android devices. iPad users opening the HTML 5 format will be prompted to download iSpring's free viewer for these presentations. Using the free iPad app, you can save the HTML 5 presentations for offline viewing on the iPad.

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.

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, 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.

Life Sciences Outreach Program The following resources were developed for classroom use by high school biology teachers who participated in MCB-HHMI Outreach's Summer 2009 "Experimental Biology and Multimedia Workshop". This year's topic was "Physiology". Keep in mind that lesson formats vary greatly because each was developed with a particular classroom in mind. All lessons align with state and national science standards as described within the lesson or in an accompanying file. Understanding Your BMI and Making Healthy Choices
