• We will be going over the Design a Habitat project today. 

Types of Selection

No Bell Work today but we are watching a video.

Click here for the survey. It is online, doesn't count for a grade and it is anonymous and it is for my grade.   

Natural Selection

In your notebook on page 140:
  Make 3 coloums and at the top of Column 1 -What we know?
Column 2- How to invesigate?
Column 3- Conclusions 

We are going outside to the "pond".

• No running.
• Don't go near the water.
• Do NOT pull out plants or swing from the trees. 

Click here for a short presentation on a dude named Darwin. 
At the end of this lesson: You will be able to understand Natural Selection.

DNA Extraction

Welcome Back!!  Hope you all had a good break but now back to reality! It is going to be a BERRY-full day!! Design a Species due Friday.
Quick Class Discussion:  Remember WAAAYYYY back in the day (like 2 months ago) when we watched Photo 51 and the scientist extracted a glob of DNA.  Now think about what you know about DNA and think of why it you were able to see it.  

Objective for Today:

• Dihybrids
• Extracting DNA from strawberries (actually seeing what you have been learning about) 

Lab

1. You will be in groups of 2 or 3.
2. Supplies: Rubber band, coffee filter, 10 ml of buffer solution, 1 strawberry, 1 10 ml graduated cylinder, 1 400 ml beaker,  and 1 test tube and 1 pipette/straw and 1 plastic bag.  

1.  You will be smashing the strawberries.  Be careful not to break the bag.

Spring Break

Happy Spring Break!!!!
 
Watching a Bill Nye video. 

Mid-term today

When you are done with the mid-term, 

Click here -- enter your ID # for the username and the password.  

Click on Student-at-a-glance (on the left of the screen).  Click on your name, and then assignments.  Your classes should come up on the middle part of the screen, click on assessments under Biology, and then take assessment.  You should be able to enter your answers there. Once complete, click save and then submit.

Mid-Term Review

Bell Work pg 126

What do the symbols mean on this pedigree? When the symbols are shaded in?

The objective for today:

1. Do pedigree problems.
2.  Review meiosis.
3.  DNA vocab- what words?

 

Starting Peidgrees

Bell Work:  on page 135..
If a person who is a carrier for cystic fibrosis (recessive trait) mates with a person who has the condition, what are the chances the offspring will be carriers?  Or have the disease?

 Today: 

• Notebook check.
•  Tape or glue pedigree pages onto 136-137.
• Finishing up "Lady Bugs": You will turn in the karyotype data table.
•  Watching video about pedigrees.  
• White boarding problems in groups.  Work through the problem together.  
• MID-TERM ON THURSDAY

Cracking the Code of Life

Today you will be watching "Cracking the Code of Life".  Answer the questions about the movie in your notebook on pages 133-134 (or the next 2 blank pages you have).   

Monday we will finish the "Lady Bug" activity.
 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.

Draw your offspring.
