Biology, 4th Quarter

00.0 Start Here (Biology)

Course Description

The Biology Core Curriculum has two primary goals: (1) students will value and use science as a process of obtaining knowledge based on observable evidence, and (2) students' curiosity will be sustained as they develop and refine the abilities associated with scientific inquiry.

The Biology Core has three major concepts:

  1. The structures in all living things occur as a result of necessary functions.
  2. Interactions of organisms in an environment are determined by the biotic and abiotic components of the environment.
  3. Evolution of species occurs over time and is related to the environment in which the species live.

Class Overview

Each quarter of Biology is worth .25 credit. Assignments should be sent via the text box in Module three (3) Lessons, Activities, Quizzes & Tests. 

Once you enroll in the class, you need to send your first assignment within one week. You do not have to do the assignments in order, but it may be helpful as they will give you knowledge about the basics in that unit.

At times if you are waiting for a reply to a question, it is fine to work ahead on the next assignment. You can send one assignment to me, or many at a time. Either way is fine. You need to MAKE SURE YOUR NAME IS ON EVERY ASSIGNMENT.  ALWAYS KEEP A COPY OF ALL ASSIGNMENTS SENT.

Make a folder on your desktop (or a Flash Drive, if you are working on a school computer), and save all your assignments there. 

As you work on your assignments, realize that the links you may need are in the course material in Topic Two in the units. I am continuously working on updating them. Please just use search engines if you find that a link is broken on an assignment you are working on. The links change so often it is very hard to keep up with them. I personally like the search engine, dogpile.com, as it includes quite a few of the other existing search engines.

You need to finish this course within nine weeks of your start date.  If you've passed the class your grade will be sent to the EHS office on the tenth week.  Please message me if you feel you need an extension to your completion date.  I am on-line each day. If you run into problems, just hold that assignment and send me a message through your class INBOX. You may go on to the next assignment or the next question in the assignment if you would like.

Grading

Each assignment within the course is worth 10 points, with the exception of a few large projects.

GRADING SCALE
A 93 - 100%
A- 90 - 92%
B+ 87 - 89%
B 83 - 86%
B- 80 - 82%
C+ 77 - 79%
C 73 - 76%
C- 70 - 72%
D+ 67 - 69%
D 63 - 66%
D- 60 - 62%
F 0 - 59%

In-class quizzes are counted as assignment grades, and the final test is worth 50% of your grade.

04.00 Heredity and DNA (Biology)

Term 4: Heredity and DNA

The information necessary for you to complete each assignment is included with the assignment itself. As you investigate many locations on the web, you will come to a better understanding of how genes are passed on and why our current understanding of DNA is so important. If you deem it necessary, you may also borrow a biology book from your local school to help you through the assignments.

04.01 Cellular Reproduction (Biology)

04.01.02 Virtual Mitosis – LAB (Biology)

teacher-scored 20 points possible 120 minutes

Summary:

  • Cells go through the cell cycle when a living organism needs new cells to repair damage, grow, or just to maintain its condition. Mitosis is one part of the cell cycle. During mitosis the nucleus and DNA divide. Mitosis consists of four major stages: Prophase, Metaphase, Anaphase, and Telophase. For this lab you will establish how long a cell will be in each stage of mitosis.

 

Instructional Procedures:

  1.   Copy all information below between the lines of asterisks, including the lesson number, revision date and   all questions into a word document.
  2.   Watch the short video titled “Onion Cell”. You may need to pause the video at each example to allow yourself time to study the picture.
  3.   Once you’ve determined the phase of each example, fill out the table in PART I.
  4.   Carefully study the picture of the magnified onion root. Complete Part II.

 

***************************************************************

ASSIGNMENT 04.01.02 - REVISION DATE: 4/14/14 (Copy everything between the asterisks.)

One purpose of the cell cycle is to aid in the growth of an organism. In a plant, the root is an area of rapid growth. Because the area is constantly growing, it’s easy to find cells that are undergoing mitosis. A thin slice of onion root, was placed on a microscope slide and stained to make the chromosomes more visible. As you look at the pictures notice the different mitosis stages that are taking place. Keep in mind that the cell cycle is a continuous process.

PART I: PRE LAB
Instructions: Watch the video titled “Onion Cells”. Each picture contains a cell that is circled. Identify the phase of the circle cell. If you need help with identifying the phases refer to URL 1 – Examples of Mitosis Phases

Instructions: Carefully examine the picture of the onion root. Count the total number of complete cells. Don't count the cells that are only partially in the picture. Count the cells that are in each phase and place the data in the table below. Calculate the percent of time each cell will spend in each mitosis phase. Add the percentages to the table.

Let's take it one more step. Choose another source to extract your DNA from and answer this question:

10. What was your second source in which you used to extract DNA?

11. Which source gives you the most DNA? How can you compare them?

Now experiment with a different kind of soap or detergent.

12. What was your new source of detergent? Do powdered soaps work as well as liquid detergents? How about shampoo or body scrub?

Experiment with leaving out or changing steps. We've told you that you need each step, but is this true? Find out for yourself. Try leaving out a step or changing how much of each ingredient you use.

13. What change did you make? How did that affect your results? Do only living organisms contain DNA? Try extracting DNA from things that you think might not have DNA.
