Today students modeled the procedure for creating DNA "fingerprints" with an activity called Who Stole the Crown Jewels? Additional time will be given in class for students to finish the data analysis and share results
Please visit the DNA sites posted yesterday to gain understanding of how this process was developed and what it is like today.
For homework tonight, please complete the review sheet that was given to you in class today.

Thursday there will be a test over the rest of our genetics unit--this includes all of chapter 4.
Remember, the workbook pages for chapter 4 are required if you did not make an 80 or higher on the last test.
Today in class we completed the activity called Family Puzzles on pages 130-131.
For homework, complete the review worksheet.
Here are a few links that I thought you might enjoy:

Wow! We did it. Bacteria have been genetically engineered with the addition of the pGLO plasmid DNA that codes for the Green Fluorescent Protein (GFP). The gene that codes for this trait was originally located in the DNA of a jellyfish.
Here are a few pictures of our genetically modified bacteria. Can you tell me why some of them fluoresce (express the GFP gene) and others that have the same pGLO gene do not?
We will wrap up our lesson next week by answering the questions on pages 41 and 42 of the student manuals.
Have a nice weekend.

Tomorrow we will begin the genetic transformation lab procedures that are detailed in your Student Manual on pages 32-37. Please take some time tonight to re-read the procedures and write yourself some notes about the time allotments for each step. You should have answered the focus questions in class today.
Advances in genetics is discussed in your text pages 132-138. Please read tis section before Friday.

Students took notes today on human inheritance from pages 118-123 in the text. You should be able to answer questions and give examples of traits that are controlled by
- a single gene with two forms, one dominant and one recessive
- a single gene that has 3 or more alleles
- multiple genes
- environmental factors
- ---and traits that are carried on the sex chromosomes
Please visit the blood typing game that was posted on the track star site posted on Friday for extra practice on blood types.
I collected the assignment from Friday from those who did not yet turn in in.
There is no homework for tonight. Students who have missing assignments should be working to complete them. Please make arrangements with me if you need to stay for extra help.

Before you begin today's lesson, take time to read the Connect 2 Science posts from Dr. Berry. Think of a good question that connects with his prior posts and write it on the paper that you will turn in for today's assignment.
There are four questions that require responses and other activities on the following sites. Read the questions and directions at the top of each frame. Answer on your own paper.

There will be a test over genetics tomorrow. We reviewed in class today and students should have several assignments from chapter 3 to study. Remember to pay extra attention to the diagram on protein synthesis found on pages 110-111.
Students who did not make an 80 or higher on the last test are reminded that the Chapter 3 Guided Reading Workbook pages are due to be checked by me for a homework grade tomorrow.
Experimental design diagrams and procedures are due tomorrow. This assignment may be written by hand or typed. Our lesson on Monday was about using an experiment design diagram to evaluate the elements of an experiment. I hope that lesson helps you in your planning. See the handout and rubrics that are on the back. I know that several students will need to revise their experiments, so do not worry about getting it perfect before submitting it to me. Do turn something in.
