Dear Students:
This week you will have a test on Chapter 4. Please read the Chapter first and then use your section summaries to review. Your class notes and work pack are also useful and available for you to review. Your test is Wednesday, September 29.
Your DNA structure project is due Friday, October 1st. DNA (Deoxyribonucleic acid) is a nucleic acid, or large molecule, that contains the genetic code or blueprint used in the creation of all living organisms and some viruses. DNA pieces are called genes. DNA comprises two long polymer strands called nucleotides, each with a backbone of sugars and phosphates. The backbone sugars are joined to rungs of two of four molecules called bases, which pair up as adenine and thymine, and guanine and cytosine. It is this sequence of four bases that actually encodes genetic information. Making DNA models is simple and can be done with household items.
Don’t forget to present your rubric with your project!!

DNA MODEL
DNA MODEL INSTRUCTIONS
Due Date ____OCT 1st___________ .
You will build a 3-D double helix (twisted) model of DNA, deoxyribonucleic acid.
Dimensions: NO TALLER than 12 inches when mounted on a base. The maximum size of the base is 8 inches by 8 inches. Smaller is better.
Use 3 dimensional objects. (No pieces of paper glued to a form) Items you may use are coat hanger wire, wire, toothpicks, pipe cleaners, beads, tinker toys, soda straws, wood, etc. NO TAPE!!!!! You may not use a purchased DNA model kit. DO NOT USE ANY FOOD PRODUCTS!!!!!!!!! No cereal, candy, pasta, rice, etc. Use of food will result in an immediate 50 point deduction in grade points. You do not have to spend a lot of money on this project. Be creative.
Your model must include a minimum of 5 rungs made up of nucleotides. Each nucleotide must have a sugar, phosphate group, and a nitrogen base represented by different colored objects. Nitrogen bases must be bonded to the appropriate complementary base on the other side of the helix. You must have each of the four bases represented. The two sides should be twisted to look like a double helix. Use Figure 23 on page 101 as a reference.
Hints for color-coding: all 10 sugars should be the same color, all 10 phosphates should be the same color, and each of the four nitrogen bases should have their own color. Together you should have 6 different colors. Again, use Figure 23 on page 101 as a reference.
Include a properly labeled, color-coded key at the base of your double helix along with an example of one complete nucleotide. List the correct names with the correct spelling of the deoxyribose sugar, each nitrogen base and the phosphates. Use NO abbreviations. Neatness AND stability of the model on its base counts. Print your name and class period on the underside of the base.
Project is due October 1.
NOTE: There are two different bases referred to in these instructions. One refers to base pairs and the other is the base of your project. Please be sure you know the difference.

September 20/ Chapter 3/ Cell Processes and Energy
Dear Students:
This week we will continue to work in Chapter 3: CELL PROCESSES AND ENERGY!!!!We will explore Photosynthesis, Respiration and Cell Division. Our Chapter TEST will be Wednesday, september 29. We will carry out activities in class to get ready for it. Our Lab Activity certainly was a big success. Slowly but surely we will continue to practice our lab skills as well as our class content. Your workpack should be ready by Wednesday, september 22. We will proceed to discuss it in class and to make sure that no questions are left unanswered. I will now list some of the goals you should meet as we approach the end of the chapter:
Explain how the sun supplies living things with the energy they need
Describe what happens during the process of photosynthesis
Describe the events that occur during respitation
Tell what fermentation is
Identify the events that take place during Cell Division
Don't forget to use the links provided in this BLOG to review your material in a daily basis, as well as the class notes.
Now lets take a look at some Effective HABITS
You can prepare yourself to succeed in your studies.
Try to develop and appreciate the following habits:
Take responsibility for yourself
Recognize that in order to succeed you need to make decisions about your priorities,
your time, and your resources
Center yourself around your values and principles
Don't let friends and acquaintances dictate what you consider important
Put first things first
Follow up on the priorities you have set for yourself, and don't let others, or other interests, distract you from your goals
Discover your key productivity periods and places
Morning, afternoon, or evening?
Find spaces where you can be the most focused and productive.
Prioritize these for your most difficult study challenges
Consider yourself in a win-win situation
When you contribute your best to a class, you, your fellow students,
and even your teacher will benefit.
Your grade can then be one additional check on your performance
First understand others, then attempt to be understood
When you have an issue with an instructor (a questionable grade, an assignment deadline, etc.) put yourself in the instructor's place.
Now ask yourself how you can best make your argument given his/her situation
Look for better solutions to problems
For example, if you don't understand the course material, don't just re-read it.
Try something else! Consult with the professor, a tutor, an academic advisor, a classmate, a study group, or your school's study skills center
Look to continually challenge yourself
