Genetics Genetics includes the study of heredity, or how traits are passed from parents to offspring. The topics of genetics vary and are constantly changing as we learn more about the genome and how we are influenced by our genes.

Cell, Socks, and Sex Cell, Socks, and Sex Description: This is a fun, easy way to teach the process of mitosis and meiosis. This will strengthen vocabulary concepts like homologus pairs, diploid, haploid, tetrad and many others. This lesson will also clear up concepts like sexual determination, trisomy and even twining. Materials: Four or five pairs of socks. Lesson Plan: I start with a long, striped piece of fabric that has been twisted hundreds of times to represent chromatin material. I use socks with colored stripes, so that I can easily make reference to the genes in them, but add the idea of homologous chromosomes and alleles. I use a similar approach to teach meiosis. Now, I add the sex chromosomes to the original autosomal chromosomes. While singing Sthe race is on and here comes Clyde in the back stretch,S the sperm swims a bit and meets the egg.

Dragon Delivery | Home | K20alt Lesson Snapshot 1. Engage: Students will watch a video or look at a picture and identify all of the similarities and differences of dragons. 2. 3. 4. 5. Ten Websites for Science Teachers We all know that the web is full of excellent web resources for science teachers and students. However, unless you live on the web, finding the best websites can become quite a challenge. This isn't a "Top Ten" list -- instead, it is a list of websites that I either use on a regular basis or just find interesting. From teaching resources for the nature of science and authentic field journals to wacky videos about numbers, I am sure that you will find something in the following list the works for you! 1) Understanding Science UC Berkeley's Understanding Science website is a "must use" for all science teachers. 2) Field Research Journals The Field Book Project from the National Museum of Natural History and the Smithsonian Institution Archives intends to create a "one stop" archive for field research journals and other documentation. 3) Evolution Berkeley's Understanding Evolution website is the precursor to their Understanding Science efforts. 4) PhET Simulations 5) Earth Exploration video
Epigenetics II: DNA Methylation in Arabidopsis Jermel Watking, Bruce Nash, and David Micklos DNA Learning Center, Cold Spring Harbor Laboratory Although DNA is the blueprint of life, not all genes are actively expressed in every cell within a multicellular organism. As discussed in our Carolina Tips® article, "Epigenetics I: Using Carolina Corn Ears to Teach Genetic Imprinting," phenotypic differences between cells occur because genes are turned on or off in a cell-specific way. Arabidopsis, FWA, and DNA methylation One very important step in plant development is the switch from vegetative growth to flowering for sexual reproduction. FWA is normally expressed in endosperm, a tissue that feeds the seedling but does not contribute to the structure of the adult. Classroom application To study this homeotic mutation, you can grow Arabidopsis seed in your class. This relatively simple experiment offers a sophisticated test for specific chemical changes to DNA that act as an important developmental regulator in plants.
Social Media for Administrators As I have done a lot of work with school administrators on why they should be using social media and some practical ways to use it within their schools, I wanted to compile some articles together that will help schools/organizations move forward. They will be listed under two categories; the why and the how. The articles are listed below: The Why The Need for Courageous Leadership – If new ideas are going to happen and we are going to encourage risks, we need to take risks as well. What Digital Accelerates – Many of the fundamentals that were important 50 years ago are still important today. Humanizing Our Organizations Through Social Media – In this post, I share what many organizations are doing around the world and how it is important that in education, we get through our culture of fear and do what we can to connect with those that we serve. There can no longer be an “opt out” clause when dealing with technology in our schools, especially from our administrators. The How
