Classification

Read these instructions and complete all parts.

Part 1 Go to this website:

http://www.pbs.org/wgbh/nova/nature/classifying-life.html  If you right click and open in a new tab or new window, you can come back to this page by switching windows.  

Go through interactive (click on the launch interactive button) and go through the three types of organisms.  Read the descriptions and try to get it right.  DON’T JUST CLICK!  When you get to the end of each organism, record your score on the paper. 

 

Part 2 You will draw a cladogram:

One kind of family (phylogenic) tree is called a cladogram.  The cladogram shows the relationships of organisms as one kind of difference occurs to each and they branch off. 

This is a cladogram for mammals.  Today you will draw a diagram showing the relationships for one of the following animals: human, eagle, great white shark, octopus, king cobra, or bullfrog. You must include, at least, 4 ancestor organisms and indicate what the difference is that branches it off from the other.  You may use the internet to research relationships.  The site http://tolweb.org/tree/phylogeny.html  is an attempt to show the tree of life for all organisms.  This may be a useful resource.

Evolution and Antibiotic Resistance

This activity is taken from the site http://ourteacherspage.com/mrb/Contact/resistance_5.html . This was originally placed by Mr. Buonagurio, and I thank him.  

Why Does Evolution Matter Now?  

Evolution and Antibiotic and Pesticide Resistance

When people go to the doctor's office, they expect to be cured. They don't like to be told, "Go home, drink lots of fluids and rest, and you will get better." They want a more proactive approach. Often, doctors prescribe antibiotics just to make their patients happy, even if the antibiotics cannot treat the illness at hand. As a result, antibiotics become more prevalent, the microbes they attack are more likely to develop resistance, and over time the antibiotics become ineffective. Learn about why some diseases have become antibiotic-resistant and how you can help address the problem.

Part A: Misuse of Antibiotics
1.	View "Why Does Evolution Matter Now?" Travel inside a Russian prison to see the impact of evolution on the lives of the inmates and the surrounding community. This video describes the transmission of tuberculosis and the evolution of multiple drug-resistant strains of TB.

2.  Answer the following questions about the video segment:

	•	Why is the Russian prison system considered to be "ground zero" in the fight against TB?
	•	What is responsible for the evolution of TB strains that are resistant to multiple drugs?
	•	How does the misuse of antibiotics affect the evolution of disease-causing bacteria? Use the theory of natural selection to explain the growing resistance to antibiotics.
	•	Why should we care about a resistant strain of TB in Russia?

I will give a 10 token bonus to anyone who shows me they survived the 1000000 years.  This will only apply to the person whose computer it is on.  I will not split tokens.

DNA gel electrophoresis

Today you will do two virtual labs and complete the question sheet.  You will get a paper copy of this sheet to complete in the library class.  If you do this another time, you can print out the sheet and complete it yourself.  

Click on this link and answer the following questions.  Please read the instructions and information as you proceed through the lab.  The questions appear in the order they are presented in the lab.

Virtual PCR lab.   

How many base pairs make up the human genome?

What is the purpose of PCR (polymerase chain reaction)?

What are 5 ingredients that you need to add to a PCR tube, to make the reaction work?

What happens during the temperature cycles in the PCR process?

How many fragments of DNA have been produced, after 30 cycles in the PCR reaction?

Click on this link and answer the following questions.  Please read the instructions and information as you proceed through the lab.  The questions appear in the order they are presented in the lab.

Virtual Gel electrophoresis lab

What is the purpose of gel electrophoresis?

2.    Is just one mRNA molecule made?  Explain.

3.    How many amino acids does each codon code for?

4.    Describe the structure of a tRNA molecule.

5.    Where does the energy to form the peptide bond between two amino acids come from?

6.    Can a single mRNA be read more than once?  Explain.

Go to:   http://evolution.berkeley.edu/evolibrary/article/0_0_0/mutations_03
Read the information and fill out the table below:

Type of mutation	Description	Effect on resulting protein
Substitution

Deletion
Frameshift

Topic:  Replication

G.   Go to:   http://nobelprize.org/educational_games/medicine/dna_double_helix/

Click on “Play DNA Game arrow in the picture”;  Click “next” and reading each page, continue to click next until you come to the game.;   Click on organism #1 and match the base pairs as fast as you can!   It is hard. 

Click Next and then click on each organism until you identify the one that belongs to chromosome #1;   continue playing the game with the other two chromosomes, filling in the chart below.

Be careful, other teams may get different results.

Chromosome #	How many chromosomes?	How many base pairs?	How many genes?	What is the organism?

DNA Mutations

Today we will be doing an activity on BrainPop about mutations.  Click on this link.  Please speak to one of the faculty to get logged in with an ID and password.  Then you will then view the animation.  After the animation do the quiz.  Please do it in the review mode first.  Then, if you like, you can score it for yourself.

When you are done with this activity you can:

•  look at any of the other activities for mutations.
• View any of the other animations on the BrainPop site, in any subject.
• Do the DNA replication matching game.  Click this link to go there.  

DNA

Today you will be completing a DNA worksheet.

• Start by viewing this video.  You may view the video multiple times, if you like.  To open in another window or tab you should right click on the link, otherwise left click.  
• You can use this textbook; DNA Structure and Function.  The information for this worksheet should be on the first few pages of the chapter.  
• You may use this link of online Biology textbook to go to the chapter on DNA.   
• You may search the internet with Google, Yahoo or any other search engine, to find the material.  

If you need help, ASK.  

When you are done have Dr Bein check and collect your sheet.  When this is done, you may use the rest of the period for free time.  

Difference between Mitosis & Meiosis

Today we will begin by looking at a meiosis tutorial.   Click on this link and follow the instructions.

If you finish early you can continue working be examining the differences between Mitosis and Meiosis, with the help of the links below.  The picture above can be enlarged by clicking on it.

You can use these links to start your exploration:

Mitosis project

For this you will complete the parts on  the mitosis tutorial and the Onion Root Tip - online activity.  This is similar to the sheet that you got, but you can click on the links instead of having to type in the addresses.  To go to the link you have to hold the Ctrl key as you click on the link.  Please write your answers on the paper sheet.  Please note that the order is slightly different on the sheets and online.
