Infectious Disease Part 2 May 15

Your group should get together and share information from yesterday - turn in your work to me - or let me check it on your computer screen.

Next, Go to http://www.koshland-science-museum.org/exhib_infectious/tracing_emerging_diseases.jsp Pick 5 hotspots for emerging infectious disease and read about the impact of disease in this area - take notes in your notebook - and show me when you finish

Finally - Go to this interactive - move the "target" around to view information about where the invaders are - and what they are. Choose 5 targets for each of the 3 invaders and descrive them in your notebook. Show me when you are done. http://www.koshland-science-museum.org/exhib_infectious/where_are_they_int.jsp

If you are done, you can play Pandemic II (see yesterday's post)

Climate and Evolution May 6, 2009

Tomorrow we are going to begin to tie together what we have learned about human evolution, extinctions, natural selection and the timeline of human migration - and relate all of this to ecosystems and climate.

First To help you begin thinking about this - take the quiz online and record the right answers and the questions in your notes http://anthro.palomar.edu/practice/ho2quiz3.htm



Secondly, using your flip book timeline of human migration - on the BACK of the flip book - map out the timeline of human evolution - For each species, explain the background of the name, give a date range for when it lived, describe its basic diagnostic features and where specimens have been discovered. Use this website http://www.archaeologyinfo.com/species.htm

Understanding Human Evolution

Today we are going to do some online activities to help you better understand how we can use genetics and anatomy to look at the timeline for human evolution and migration.

Finish your timeline we started in class by going to the ATLAS OF HUMAN JOURNEY site and clicking on journey highlights under at the bottom right of the image. Find at least 1 more highlight to add to each of the year tabs on your timeline.

Now you are ready to look more closely and genetics and human evolution.

The first activity is a chromosome matching activity called the CHROMOSOME CONNECTION
When you are done with it - answer the following questions:

  1. How many chromosomes do we have in common with all three primates used?
  2. How many chromosomes do we have in common with our closest relative?
  3. What is our closest primate relative- how do we know?

The second activity looks at similarities and differences between primate anatomy and human anatomy that have allowed us to be bipedal (walking on two legs) and walking upright. BUILDING BODIES Drag bones from the bone box to either the human or primate column.

  1. How can researchers use the foramen magnum in a skull to tell if it was an upright walker or a four legged walker?
  2. Describe other differences between the primate and the human skull.
  3. How do human pelvic bones (hips) look different from primate pelvic bones?
  4. How can researchers use the pelvic bones to tell if it was an upright walker or a four legged walker?
  5. What would you expect the spine of an upright walker to look like?
  6. The femur is the thigh bone. Compare the femurs of the human and the primate - what do you notice that makes the femurs of the human- upright walker - different from the primate?
  7. The lower leg bones (tibia and fibula) are also different in the human and primate. Why would the human bones need to be longer and thicker?
  8. Look at the angle of the humerus (upper arm) and the shoulders in the primate and the human. Explain why you think they are different?
  9. Why are the primate's upper arms longer and thicker than the human?
  10. How are the thumbs and big toes different in the primate and the human?
  11. If you were a paleontologist, which fossil bones would be most helpful in deciding if the specimen was an upright walker?
  12. If you were a paleontologist which skull pieces would be most useful in determining if the specimen was an upright walker?
For the last activity - take a look at evolution and our choices to pick a mate- what did you answer after each page of information? How did your final answer compare to those of everyone else who took the survey? EVOLUTION AND LOVE

For Or Against Genetically Modified Organisms?

We are going to be debating a group of students from Greene County JVS on March 10. We will be debating whether or not we should be genetically modifying organisms. Today you need to find 4 sources that are either in favor of doing this or against doing this.

HERE IS THE ASSIGNMENT to help you get ready for the debate.

Genetics and Designer Babies - Looking at Ethical Decsions

Yesterday in class - you and your partner created a baby - using coin flips to model the random selection of alleles that are contributed by both parents. Right now, we have no control over what genetic combination our offspring will receive. Read the article "Genetics Will Let Parents Build Their Baby" .

Answer the following questions:
  1. Would you choose to genetically "program" your baby?
  2. Do you think it is RIGHT to offer parents the ability to pick and choose the traits they would like their child to have? Explain.
  3. How would you feel if you knew that you are the way you are because your parents MADE THE CHOICE to make you a boy or girl, picked your hair color, your intelligence etc. What problems might this cause?
  4. The experts think that the ability to program the child would make our world even more competitive - do you agree or disagree with this? Explain
  5. Would it be ok to program genes for health reasons? How would this change society?
  6. If you knew in advance that your child carried a gene for cancer or some other disease - would that effect your decision to Have the child? Or would it influence how you treated the child once they were born?
  7. George Annas feels that genetic engineering will add to the divide between rich and poor - explain your thoughts on this? Why do you think he feels this way?
  8. Post a comment on this blog explaining your point of view on Genetically modified kids - give at least 3 supporting details to back up your opinion. The post won't show up immediately - I moderate the blog.

Genetics and Study Island Feb 24

Today you are going to do some interactive genetics activities to learn more about dominant and recessive traits.
Go to http://nature.ca/genome/04/041/041_e.cfm
Do PASS THE GENES and MIX THOSE GENES

When you are done, write up an explanation of what you did and what you learned about genotype, dominant and recessive traits.

Then, go to studyisland.com and work on your assignments. Remember, people who have NOT taken the OGT or NOT PASSED the OGT need to do any assignments EXCEPT the biology assignments. Juniors who have passed the OGT SHOULD be doing the cells, evolution and genetics assignments.

Taking a Fieldtrip With Charles Darwin

Yesterday you had a chance to read about how Charles Darwin's ideas and observations have effected science for the past 100+ years. Then, you had a chance to see how he started to develop his ideas by making his journey on the Beagle. Today you have a chance to take a fieldtrip with Darwin - this is an interactive site. You are going to learn that Darwin didn't come up with the THEORY of EVOLUTION - he came up with the THEORY OF NATURAL SELECTION - which is HOW evolution occurs.

TODAY'S FIRST LINK - use the red arrows to advance through the first 4 slides - then use the blue arrow at the bottom of the box when Darwin appears - Answer the questions that are asked on the trip - Answer questions 1-6 to turn in.

  1. What are the 3 misconceptions about Natural Selection?
  2. In your own words, explain what we can learn about Survival of the Fittest from Cave Salamanders?
  3. Define FITNESS according to Darwin
  4. Explain how phenotypes prove that Natural Selection isn't random. Give examples.
  5. Define Environmental Selective Pressure
  6. Why did long tongued salamanders have higher fitness than the short tongued ones? Explain how this shows that Natural Selection doesn't create variation.

TODAY'S SECOND LINK - Understanding the Genetics of Variation
Play FITNESS FEVER and keep a log of what you learn about your fish. READ THE INTRODUCTION SCREENS.

IF YOU HAVE TIME - Play the FISH ADAPTATION GAME
  • How are the different kinds of fish living near the reef alike? How are they different from one another?
  • Did the fish that you built succeed in the reef environment? Why or why not?
  • In what ways is this activity related to the evolution of coral reef fish?
  • Explain what it means to say that a fish is adapted.

Happy Birthday Darwin

Today and tomorrow we will be using computers to research the impact Charles Darwin had on the science of genetics and our understanding of how living things have evolved over time. Darwin developed the theory of Natural Selection based on observations he made during his trip aboard the Beagle.

Using THIS ARTICLE answer the following questions:
  • Explain at least 3 of Darwin’s observations of nature that led to his ideas (Darwin's Big Ideas)
  • Why is evolution via natural selection the basis of all of biology? (Darwin's Big Ideas)
  • How do Darwin’s ideas influence our understanding of the sciences?(Darwin's Big Ideas)
  • How does evolution continue to affect us today? (Darwin's Implications)
Using THIS WEBSITE develop a timeline for the voyage of the Beagle - include the 9 main dates, give details of the location and give specific details about what scientific activity Darwin did while at this location. - do not just use the info on the main page - click on the "go here" links

Onion Root Tip Mitosis Lab

We are going to be looking at onion root tip slides with our microscopes to see cells that are going through the process of mitosis. Since cells go through this process all the time, we will be able to see different phases going on in the same root.

Why do you think we are using root tips to explore mitosis?

Here is a weblink to do the lab online http://www.biology.arizona.edu/Cell_BIO/activities/cell_cycle/cell_cycle.html

Here is a vocabulary page to help you with terms http://www.biology.arizona.edu/vocabulary/mitosis_meiosis/mitosis_meiosis.html

What Do We Know About Genetics and Diversity?




Here are our ideas about Mitosis
Mitosis is necessary/valuable because:
- it makes copies of cells
- growth would not be possible without mitosis
- allows more of the same cell to be made
- splits the nuclear information in half then copies it
- lead to the devlopment of cancer

This is what we know about inherited traits
- you get them from your parents
- this process can not be controlled - can't pick and choose traits
- dominant and recessive traits
- evolution happens because successful traits can be passed along to future generations
- how is alcoholism hereditary
- can a trait skip a generation

This is what we know about evolution
- mistakes in your DNA can lead to evolutionary change
- it got us where we are today
- Are people still evolving?
- How is the idea of Intelligent Design related to this concept?

Charles Darwin - theory of evolution - natural selection, survival fittest
Miller - Urey - the experiment that showed that it might have been possible for amino acids to form on Earth
Watson and Crick - came up with the shape of DNA module
Gregor Mendal - created the concept of inherited traits.





Here is a list of the questions we came up with about Genetics. This is also a list of what we already know about Genetics.

DNA is shared
How do the genes fit together to make traits?
How do we get traits from parents?
Does DNA have anything to do with human race?
Stem cells can become any kind of cells
Genes can be passed through sexual reproduction
Genetics is the study of heredity.
Genetics are passed from generation to generation.
Genetic family traits can be seen across generation.
Can genetic makeup be changed without mutation
What part of genetics is the biggest part of our daily lives.

Charles Darwin -
he invented something
natural selection
geologist
theory of evolution
Scopes trial
Galapagos Islands
Studies Finches
Ship name beagle

Stem Cell Webquest

We have spent time looking at the parts of a cell and different kinds of cells. We are going to be learning about how cells know what kind of cells to be and how DNA actually works. One of the hot science issues that the new Obama government will be looking at is stem cell research. Today's webquest will help you to learn about stem cells (with nice little cartoon interactives) and current research being done on stem cells.
