Rediscovering Biology - Case Studies: The Genetics of Resistance to HIV Infection This case uses the example of HIV, to explore the relationships between viruses, cells and the immune system, and the role of genes in disease resistance. An animation explains PCR (polymerase chain reaction) and electrophoresis and their practical use as a genetic test. We will see how mutations in an HIV receptor confer relative reslstance to infection. We will find out how often this mutation occurs in the general population, and see data about additional mechanisms of HIV resistance. Developing Independent Learners – The 7 Monkeys! The 15 minute forum tonight was led by our two science NQTs – Faye Hedley (@f_hedley) and Becky Owen. They shared a strategy they have been using called ‘The 7 Monkeys’. The 7 Monkeys is a way of enabling students to learn a concept, process or idea independently with minimal teacher input.

Looking For Biodiversity This lesson plan may be used to address the academic standards listed below. These standards are drawn from Content Knowledge: A Compendium of Standards and Benchmarks for K-12 Education: 2nd Edition and have been provided courtesy of theMid-continent Research for Education and Learningin Aurora, Colorado. Grade level: 6 - 8Subject area: Life ScienceStandard: Knows about the diversity and unity that characterize life.Benchmarks: Knows ways in which living things can be classified (e.g., taxonomic groups of plants, animals, and fungi; groups based on the details of organisms' internal and external features; groups based on the roles within an ecosystem, such as producers, consumers, and decomposers).

Cell Models For life all cells have basic needs. Cells have diverged in their structure and function to accommodate these survival requirements. Here are some KEY TERMS to help you think, explore and search for similarities and significant differences that have become the characteristics of eukaryote (animal, plant) and prokaryotic (bacteria) cells. Examples might be searching: eukaryote prokaryote reproduction or animal plant cell energy. 50 Really Cool Online Tools for Science Teachers A 21st-century education revolves around the Internet for everything from collaboration, tools, lessons, and even earning degrees online. If you are looking for ways to integrate online learning into your science class or science degree programs, then take a look at these cool online tools that are just perfect for both teachers and students. Science Tools to Use with Students These tools offer opportunities for learning about climate, cells, the human body, nature, and more. ChemiCool.

Male Chromosomes Are Not Dying Soon, Study Finds : News Update Date: Jan 11, 2014 05:31 PM EST A new study has challenged the notion that Y chromosomes are largely unimportant and will no longer exist in the next 5 million years. (Photo : Image Editor/Flickr) A new study has challenged the notion that Y chromosomes are largely unimportant and will no longer exist in the next 5 million years. The study has based its findings on a comparison of Y chromosomes in eight African and eight European men. Lesson: Nat. of Sci. mini-lesson: Checks Lab Before Doing this lab, consider doing the NEW High-Tech Version: The E-Mail Lab. (Details below under EXTENSIONS AND VARIATIONS. TEACHER PREPARATIONS: 1. Because this lesson provides an excellent opportunity to understand important elements of the Nature of Science , be sure to read our General Background Information, with our Rationale and our Approach, and tips for Presenting the lessons for maximum effect and Dispelling some of the popular myths about science. 2. In any of the discussions expected with the class, select a few key items (important concepts) that lend themselves to interpretation, and introduce class to the Think-Pair-Share (TPS) routine dealing with those items.

Biodiversity Teaching Materials » www.pathwaysproject.kbs.msu.edu Blog Biodiversity: Research Professional Development Materials Assessments Scientist Leila Desotelle talks with students about stream macro-invertebrates at Kellogg Biological Station. Target Grades: Middle School and High School (modification suggestions for each level are included) Description:Students will explore functional and taxonomic diversity in a stream ecosystem, learn about food web relationships, and learn about the ways in which abiotic and biotic factors determine what organisms are present in a community. Students will make and install leaf packs in a stream, wait for the leaf packs to be colonized by stream organisms, measure abiotic variables that could influence leaf pack colonization, retrieve the leaf packs and classify the organisms they find in both taxonomic and functional ways, and discuss how the leaf pack community is situated within a larger ecosystem. Assessments — Assessments include student tests, teacher tests, and interview protocols.
