We will not be using warm up folders today, but we will be using the following article for our warm up. Click here to open the article on the Florida Panthers. On a seperate sheet of paper you will answer the following questions. This will be turned in today, as an assignment grade. 1.Describe genetic variation. 2.What are the short term and long term impacts of low genetic variation on a population. Create a T chart to show this evidence. 3.Paragraph 1 and paragraph 4 use the phrase “new blood”. Explain the meaning of “new blood” and the effect of new blood on the Panther population. 4.Using evidence from the text, explain why genetic variation is important for species survival. 5.This article was written over 6 years ago (December 2010). Do you still think this article is important? Explain your response. Next, we took notes on Homologous and Analogous Structures on page 58. If you were absent today, here are the notes. Finally, we did a round the room activity going through 9 stations on evolution. These stations reviewed Geological Evolution (Pangaea, continental drift) and Biological Evolution(natural selection, genetic variation) Quiz next class will cover
Natural Selection Adaptation Mutation Evolution Analogous & Homologous structures

Warm Up - Is it "fitter"? Read the following situation about the "fitter" organisms. Answer the question in your warm up folder Next, we did a quick review of genetics. The Genetics 101 notes will go on page 57 in your notebooks. Here are the notes if you were absent. This should all be a review from 7th grade. For our assignment today we took at look at different adaptations for plants and animals using stations. As a class we read an article on Adaptations, which is station 4. Station 1 was vocabulary. You can use www.vocabulary.com for the definitions, make sure you look for the scientific definition. Stations 2 and 3 are handouts that you can pick up from the back of the room. I also attached the handouts below. Below are the links for Station 5: http://www.nhptv.org/natureworks/nwep1.htm http://studyjams.scholastic.com/studyjams/jams/science/animals/animal-adaptations.htm
Our warm up today was a review of natural selection and adaptation. Next we went over the natural selection homework and reviewed the peppered moths. Next we completed a bird beak lab. Using 4 different types of beaks and 4 different food sources we competed for food. Some of you made adaptations with your beak by flipping it around, some of you died out because you couldn't pick up any food. After completing the lab, we graphed the results and completed the conclusion. If you did not finish the conclusion, here are the questions.
1. According to your results, out of all the beaks, which species has nature selected for? Which species has nature has selected against? 2. According to your results, which “worm” is nature selecting for? What species has nature selected against? 3. If we looked at this population of birds and worms in the next 5 years, how do you think the population will change? 4. How does this activity demonstrate the concept of natural selection? Warm Up - Read this article on Vestigial Organs and answer the questions from projector in your warm up folder. Next, as a simulation of natural selection, we went outside to hunt down some wacky mac. The purpose of the the simulation is to show how nature selects for a specific species. We finished up our notes from page 54 in our notebook on Natural Selection and Adaptations. If you were absent, here are the notes.
The handout you received today, titled "Darwin's 5 Points of Natural Selection" is a review of the theories used to support Darwin. You can find this handout here if you lost it, it is due next class. The link has 2 pages, we are only doing page 1.
Finally, we completed an activity simulating natural selection using the Peppered Moths and Industrial Revolution. The website for this activity can be found here. Students clicked through the website and answered questions on the Peppered Moths on page 55 in their notebooks. Here is the handout from the Peppered Moth activity.
Wacky Mac...what did nature select for??? This is where you will find information on High School Lottery for magnet schools as well as for Olympic lottery. Please look over thiz website. There is some great infomation about the different highschools.
Watm uptoday was introduction to evolution and adaptations.
Next we organzied our notebooks for the new unit. New cover sheet, new table of contents...our unit will be called EVOLUTION, ENERGY and ECOSYSTEMS. Our unit on evolution sometimes can be a bit contraversial so to start the unit we go over the diffrences between Laws and Theories on the back of page 52. Evolution is a theory. For the new unit, we started off with some vocabulary. On page 53 in your notebook. Define the following words(use the textbook). You will have to use the glossary and/or the index. 1.Mutation 2.Natural selection 3.Adaptation 4.Vestigial organs 5.Evolution 6.Speciation Next we watched some video clips on biological evolution through Discovery Education. DISCOVERY EDUCATION Search: Elements of Biology: Biological Evolution Watch the following and fill in the video guide. 1.Introduction to Charles Darwin 2.A new Understanding of Life 3.From the Big Bang to Early Life 4.The Evolution of Complex Organisms (questions 7-8) 5.The Proliferation of Species 6.The Evidence for the Theory of Evolution |
