Evolution & Taxonomy Evolution is often called the “unifying theory of biology” because it organizes all of the observations gathered by biologists and proposes and explanation for those observations. All state standards for teaching science include a section on evolution (sometimes called adaptation or change over time). Evolution Peppered Moth Simulation – newspaper and colored paper simulated natural selection Peppered Moth Simulation Kit – similar to above, only uses a purchased kit from Neo Sci. Evolution Concept Map – graphic organizer, shows terms related to evolution and how they are connected Evolution Crossword Puzzle – terms related to topic of evolution; darwin, galapagos, selection..etc… – Berkeley interactive activity with questions Comparing Life History to the Hours of a Clock – place events, such as “bacteria evolve” on a clock The Decay Curve of Twizzlers – use twizzlers candy to understand the decay of isotopes and how that decay is used for carbon dating Taxonomy
Honors Genetics Use of our material: We have worked very hard on Powerpoints/games/worksheets, etc to make this a resource for our students. If you are using our materials, please give us credit for our efforts by listing us as a source with links to our site. High School Life Science Conceptual Understanding: Heredity is the passing of characteristics from one generation to the next via genes. Chromosomes are single long DNA molecules which carry the instructions for forming particular species characteristics. Genes are a segment on the DNA that code for a particular trait. An alternative form of a gene found at the same place on a chromosome is called an allele. HS-LS3-1 Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring. High School Life Science Standards (Grades 9-12) Indicator 1: Understand the fundamental structures, functions, classifications, and mechanisms found in living things.
Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.

British Couple Clones Dead Dog For $100K On Dec. 26, Laura Jacques, 29, and Richard Remde, 43, of Yorkshire, United Kingdom, welcomed two new puppies - dubbed Chance and Shadow - cloned from the DNA of Dylan, their deceased boxer, the Guardian reports. Dylan died of a brain tumor in June at the age of 8. [READ: Do You Love Your Dog More Than Humans?] The couple sent his DNA samples to Sooam Biotech Research Foundation in South Korea, which offers a commercial dog-cloning service for about $100,000 per procedure, according to the Guardian. Sooam Biotech, the only laboratory of its kind in the world, has successfully cloned hundreds of dogs, though Dylan's is reportedly the oldest sample from which a dog has been cloned successfully.
The Immortal Life of Henrietta Lacks With Henrietta unconscious on the operating table…though no one asked if she wanted to be a donor—[Dr.] Wharton picked up a sharp knife and shaved two dime-sized pieces of tissue from Henrietta’s cervix. – The Immortal Life of Henrietta Lacks, pg. 33 Informed consent is a legal procedure to ensure that a patient or client knows all of the risks and costs involved in a treatment. A Guide to Understanding Informed Consent (National Cancer Institute) Making a decision about participating in a research study involves understanding the potential risks and benefits as well as your rights and responsibilities.

Worksheets by Topic Couple Spends $100,000 To Clone Deceased Dog, Gets Two Puppies Lipids Lipids The lipids are a large and diverse group of naturally occurring organic compounds that are related by their solubility in nonpolar organic solvents (e.g. ether, chloroform, acetone & benzene) and general insolubility in water. There is great structural variety among the lipids, as will be demonstrated in the following sections. You may click on a topic listed below, or proceed page by page. Fats, Oils, Waxes & Phospholipids 1. The common feature of these lipids is that they are all esters of moderate to long chain fatty acids. The higher melting points of the saturated fatty acids reflect the uniform rod-like shape of their molecules. Two polyunsaturated fatty acids, linoleic and linolenic, are designated "essential" because their absence in the human diet has been associated with health problems, such as scaley skin, stunted growth and increased dehydration. 2. Very small amounts of these surfactants dissolve in water to give a random dispersion of solute molecules. 3. 4. 5.
Current Classes Practice Exams for Genetics These practice exams were put here to help you monitor your progress in genetics. Do not study only these questions as new questions will be written for each test and old questions will be modified. It is important that you understand the question and why the correct answer is correct. Exam #1 Chapter 2 -- Chromosomes and Cellular Reproduction Chapter 3 -- Basic Principles of Heredity Chapters 4 and 6 -- Sex Determination, Sex-linked Traits, Pedigrees Chapter 3 -- Probability and Statistics Exam #2
Anatomy (Dissections) Most biology classes will have some form of dissection – the frog is the most common. However, if you do not do an actual dissection, many of the sections below contain links to virtual dissections and image files. Fetal Pig Fetal Pig Dissection - procedure for the dissection Fetal Pig Dissection Review - resources for studying Fetal Pig Lab Guide – lists structures and check boxes Fetal Pig Gallery – collection of labeled and unlabeled images Frog Dissection Frog External Anatomy - legs, eyes, mouth structures Frog Dissection - major organs of the digestive, urogenital, and circulatory and respiratory systems Frog Brain and Bones – remove the frog’s brain, expose the bones of the lower leg Frog Dissection Crossword – review terms and procedures Observe a Living Frog – non dissection, behavior and characteristics Bullfrog Dissection – bullfrog dissection guides, more advanced than basic frog dissection Frog Dissection Gallery – collection of labeled and unlabeled images of the frog Human
Fruit Fly Tutorial Index In this virtual lab we will cross various fruit flies to see what phenotypes are present in the F1 and F2 generation. Using the data from these crosses, we will make a hypothesis regarding the genotypes of the parental (P) generation and test the hypothesis using a chi square analysis. **Print out a copy of the Data Page **Review how to do a chi square analysis Background Information Drosophila melanogaster is a fruit fly, a little insect about 3mm long, of the kind that accumulates around spoiled fruit. It is also one of the most valuable of organisms in biological research, particularly in genetics and developmental biology. See mutant fruit flies You can order mutant fruit flies from any biological company and perform crosses in the lab that will generally take about two weeks. How to Raise Fruit Flies 1. Terminology Wild-type - flies that have the "normal" characteristics, red eyes, normal length wing and brown bodies. Mutant flies - any variation from the wild type. Genetic Notation 1.
