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.

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.

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.

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! The Quiz” at the front of the room. 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. 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.

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
