Use Hardy Weinberg equilibrium to analyze data of rock pocket mouse populations in the desert. The allele frequency of dark color will increase in populations living on dark substrates.
This story, told by one colorful figure among the anarchists of Philadelphia, does not tell the entire story of the city's movement, nor does one man's experience with anarchism present the long and dramatic saga of the idea and its believers. The memoirs of Chaim Leib Weinberg offer an interesting sliver of a larger picture, holding to an exclusively working class, folkloric niche. The author was an incredible orator and story teller: these were the talents that set him apart from most of his contemporaries. Because he devoted half a century to practicing his oral craft, he left a clear mark on the radical culture he lived within.

This activity aids students in understanding the conditions of Hardy-Weinberg without having to use the equation. Students examine a population of "beetles" (you can use any items that come in red, yellow, and orange (beads, jelly beans, construction paper, etc) and see how the allele frequency changes (or doesn't) in three generations. The class discussion that happens as you work through the activity will leave students with a clearer understanding of Hardy Weinberg equilibrium. A prior understanding of genetics will be helpful in this activity, but it could still be done with additional teacher instruction if genetics has not be previously covered. Materials needed: small items that are red, yellow, and orange in color (see suggestions above), lab handouts, calculator

The Hardy Weinberg Goldfish Lab is an edible, hands-on activity to help students understand the Hardy Weinberg Principle.
This fun lab simulation should guarantee that your students understand the Hardy Weinberg Principle! I talk to a lot of biology teachers. Everyday. Some are in my school, some are at other schools in my district, others I know "virtually" from various message boards that I read and post to. Through these communications, I have come to realize that many biology teachers do not include the Hardy-Weinberg Principle in their lesson planning. I know that all biology teachers have their own "order of events" but for me a unit on genetics, followed by my unit on evolution is perfect. In fact, I would be hard pressed to do it any other way. The Hardy-Weinberg Principle is the link between genetics and evolution. It is the proof that we offer to our students that populations are constantly changing and evolving. It allows us to mathematically show that the frequency of a particular allele in a population can change over time. Simply put: Evolution is any change in the frequency of alleles in a population. Evolution is the result of changes in the gene pool. Two men, G. H. Hardy and W. Weinberg, proposed a mathematical model for detecting changes in the gene pool. The Hardy-Weinberg Principle states: “In the absence of mutation, migration, and natural selection, and in a population that is sufficiently large, the frequencies of alleles will remain the same.” The Hardy-Weinberg Principle is represented in the equation: No population is free of these agents of change. The Hardy-Weinberg equation is used to detect changes in the population from one generation to the next. Since no population in nature is free of mutations, migrations, and natural selection, and since mating is rarely completely random in nature, of what value is the Hardy Weinberg Principle? It allows us to detect changes in the gene pool, and therefore, determine that a population is in a state of change....Evolution! My experience with my own students is that some of them have a little trouble grasping this concept. After introducing the topic and working through quite a few practice problems, I do a simulation lab. Purpose of the Lab: 1. To simulate how changes in the gene pool might occur by using the class as a breeding population of individuals. 2. To observe how the Hardy-Weinberg equation is used to detect changes in allele frequencies in a population. Materials: PTC test papers, Calculator, Allele cards, Coins, Pencil and paper Safety Precautions: None The student handouts for this lab are numerous.....12 pages! I usually run off a class set and have students record all of their information on notebook paper. I use the class set throughout the day, and then I file them away for use the next year. I have also included an 11-page teacher guide. The teacher guide has tips and tricks for making the lab successful as well as answers to questions and solutions to problems. Sample data is included to give you an idea of what to expect in the simulation. Students begin the lab by determining the frequency of an allele in the class population. I like to use PTC paper to determine if students are tasters or nontasters. But if PTC paper is not available, you can choose another trait such as the presence or absence of dimples, or the ability to roll the tongue. From the number of recessive individuals in your class, the value of q can be determined. From that point, the students will determine what percentage of the class is homozygous dominant and heterozygous for the given trait. Next, students will run three simulations: (1) Testing the Hardy-Weinberg Principle, (2) Testing the Hardy-Weinberg for Selection Pressure, and (3) The Heterozygote Advantage. Students will begin the simulation as heterozygous individuals and will use allele cards to generate offspring. Students proceed through several generations of "mating" and the data is used to test the different conditions of the Hardy-Weinberg Principle. During each simulation, students will determine the frequency of the dominant and recessive allele and note how the frequency of p and q change in various scenarios. The lab concludes with follow up questions and 8 additional practice problems involving the Hardy-Weinberg equation. The end result? My students have mastered the concept and are able to work problems involving the Hardy-Weinberg equation. Good luck, and have fun teaching!

Recently, blog readers have asked me to write about scope and sequence in my biology class. Determining the best scope and sequence for your students is very difficult as a new teacher. It’s so hard to know! What do I cover? When? And to what depth? I have found that my own personal preferred scope […]

OVERTURE TO WEINBERG Abstract musical instruments in the style of Frederick Weinberg. Mid century modern living. This is a limited edition (200 prints) print by Linda Tillman. It is a print of an original gouache painting. Prints are all printed on archival matte paper. They are printed with a Canon iX6500 printer. Each print has a colored border as on the original painting. The edges of the composition fade softly into white as they do on the original painting. The print will fit a standard pre-cut matte for easy framing. The size is 11 x 14 inches Each print is titled, numbered, and signed on the back and shipped in a protective sleeve. **I ship everything USPS Priority Mail within the UNITED STATES. **** For international customers, I use 1st Class International Visit my other Etsy Shop, EccentricAvenue.etsy.con, for downloadable Mid Century Modern cross stitch patterns and printable wall art.

Sorry for the lack of *cleverness* in the title of this post... but trust me, this is a fun and simple project - that costs almost nothing! {That's pretty much my favorite description when talking about a holiday decoration} Let me introduce to you: Valentine Clothesline {Wall} Art! Here's what you need: 11"x14" canvas 1.5" heart shaped scrapbook punch {or cut them by hand!) Paint chips Mini clothespins String, twine, etc {I used black embroidery thread} Head over to the store and pick out a color in the paint chip section. Take about 500 a few. Because I'm a non-traditional girl, I didn't want to necessarily use traditional bright pinks or reds. So, I chose a color that was in between: Watermelon Smoothie by Glidden. I used about 4 or 5 paint chips total for this project. The other 495 will most likely be used for some other project soon enough... Punch out or cut 16 hearts out of the paint chips. Or more. Or less. Really, you are the one who will have to look at it, so put as many as you want. This is just a suggestion... You can paint the canvas if you want, but I just left mine blank. Tape one end of the string/twine/black embroidery thread to the back edge of the canvas toward the top, maybe an inch or two down. Wrap around the canvas until you have four lines going across the front and tape the end of the string securely on the back of the canvas toward the bottom. Take those mini clothespins and clip the hearts on the string! You can have them all in the same direction, or switch things up like I did and have them a little crooked. Refer to the second step in this tutorial. Last, but not least: Hang that artwork up and fall in *love*
