Infectious disease

An infectious disease is any disease caused by germs that can be spread from one person to another. Germs include viruses, bacteria and protozoa. What are some infectious diseases? 

This activity will simulate the spread of an infectious disease. A simulation is a simplified demonstration of a real biological process. Our simulation will show how an infectious disease can spread from one infected person to other people, who in turn infect others. 

Instructions 
1. Your teacher will give everyone a cup filled with a clear solution. This solution represents your body. Only one person in the class will have a cup that has been “infected”. Obviously, you should not drink from the cup. (In laboratory activities you should never drink or eat anything unless your teacher tells you that it is safe to do so.) 
2. In this part of the activity, you will interact with two other students. To interact with another student, pour all of your solution into your partner’s cup. Then have your partner pour all of the mixed solution back into your empty cup. Finally, pour half of the mixed solution back into your partner’s empty cup. Wait for the signal from your teacher, and then move to another part of the classroom and interact with a second student. After you have finished your second interaction, return to your seat. Estimate how many people you think will be infected. ________ 
3. Your teacher will come around and put an “infection indicator” in your cup. If you have exchanged solutions with the original infected person or someone else after they became infected, you are now infected and your solution will turn pink. If you have not exchanged solutions with anyone who was infected, your solution will not turn color. Next, your teacher will ask everyone who is infected to raise their hand. How many people were infected? ________ 
4. You will do another set of interactions, again beginning with only one student with an infected cup. This time there will be three rounds of interactions. For each interaction, be sure to move to a different part of the room with different students. Estimate how many people you think will be infected after each student has interacted with three other students. ________ After the teacher has come around with the indicator, write down how many people were actually infected. ________

 Have a great weekend!!!

NOTEBOOK CHECK ON MONDAY!!! TEST ON THURSDAY!!!! 

Lady Bugs

Bell Work Question:  
   What is the term used when a person has the gene for a disease but does not have the symptoms?

The objective of today: Click here for today's presentation.

• You will investigate genetic disorders.
• Be able to identify chromosome abnormalities. 

 

Vocab from yesterday:
Sex Linked Traits: the chromosomes that determine whether the offspring is going to be male or female.  X chromosome.
Carrier:  a person or organism that has the recessive alle of a mutation or genetic trait but does not show the trait or disease.  

Flip-A-Coin

Bell Work ( on page 126)
   What is the difference between genotypic and phenotypic ratios?


Today:

• We are learning about sex-linked traits
• We are learning about genetic carriers.
• In pairs you will be building an offspring. 

On page 130

•  Top Half: vocab words :sex-linked and carrier
•  You will be in pairs: each person will flip a coin to see what traits your offspring will have.
•  On the bottom half of the page write genotype and phenotype of your offspring.

Page 131
Draw your offspring.  

Flower Dissection

BW -- pg 126
 We have been learning about Mendel's experiments with pea plants.  Biologists use plants all the time.

1. Why?

The objective for today: Tape onto 127 and 128

• We are dissecting flowers today. 
• Be able to identify the parts of the flowers.
• Answer the questions.
• Use the dissection microscope to view the parts.
•  While you are looking at the flowers, look at the phenotype.  Do you think it could be codominance or incomplete dominance?
• What could the genotype be?

Second part of class: Tape 129
     You are starting "Design a Species"

• Work in groups of 2 or by yourself.
• Go over instructions.  

  

Spongebob Genetics

Bell Work ( on page 119) 
 A cross between a black cat and a tan cat produces a tabby pattern (black and tan together).
 

•  What pattern of inheritance does this show?
• What percent of kittens would have tan fur if a tabby cat (BT) is crossed with a black cat (BB)? (Hint: use a Punnett square).

Today you will be able to use what we learned about Dominance of Alleles to do practice problems.  Click here for the problems. 
 You will white board your answers and then show them.   
REMINDER: Please bring in the permission slips for the video taping!!  

Types of Dominance

More Bell Work but on your whiteboard.  

What do you notice about the flowers?
 Write down at least 2 observations.

Tape Dominance of Alleles onto 125.  

• In groups of 2, one person will read about Incomplete dominance and the other co-dominance.
• After reading it you will explain it to each other. 

For those that were gone yesterday:

•     Read yesterday's blog for what we did.
•     There are problems to be taped into your notebook.  

 

Practice Problems

 Bell Work -continued on page 119

 Suppose Mendel had made his observations a few decades later when there as more widespread knowledge of chromosomes throughout the scientific community.  How do you suppose this may have impacted the development of his theory? 

 It is going to be a PUN-tastic day.  Today we are working on more Punnett square problems.  
  Problems 1-3 goes on page 122
  Problem 4  goes on page 123.
