Biology, 3rd 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- 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.

teacher-scored 10 points possible 120 minutes

In this assignment you will be completing two experiments to help you understand the terms "diffusion" and "osmosis" and also to help you see how important these mechanisms are to cells. Before you begin, write down the definitions of "diffusion" and "osmosis" as part of the assignment. You will also need to make a data table to keep daily observations on your experiments. After the experiments are completed, answer the questions below.

The materials you will need for the first experiment are as follows: 

3 - 10-12 ounce glasses 

string 

vinegar 

measuring tape or meter stick

Karo syrup

salt 

distilled water

eggs

food scale

 

Follow the procedure below to complete the Egg experiment:

1. Place 3 eggs in a glass of vinegar. Let eggs remain in beaker keeping eggs completely covered for 3 days or until outer shell is dissolved.

2. Remove eggs from vinegar, rinse off. Determine the weight and circumference and record on a chart.

3. Place eggs in separate glasses and cover with equal amounts of distilled water, Karo syrup, and salt water. Record volume of liquids.

4. Daily determine weight and circumference of eggs and record.

5. Conclude experiment in 4-5 days. Take final measurements: weight and circumference of eggs, and volume of liquid.

6. Discuss answers to these questions:

Egg Experiment Questions:

1. Which egg is the largest? Why?

2. Which egg is the smallest? Why?

3. How much liquid was left? Why did the amounts of liquid vary?

4. Could the egg represent a model of a cell with cell membrane? Why or why not?

5. Is this process diffusion or osmosis? Explain.

 

The materials needed for the second experiment are as follows:

Two tall glasses

Water

Salt

Summary:

Now that you've learned about cells, cell chemistry, properties of elements in cells and much more, let's put a little of that to use in our everyday world. Sure, you understand that you and other organisms are made up of cells and that cells have an important function in our bodies. You have researched the macromolecules (proteins, carbohydrates, lipids, nucleic acids), and you have looked at some of the major elements that play a role in the makeup of the human beings and all other organisms. Don't forget that inorganic materials (those not containing Carbon - nonliving factors in our environment) are also present in our everyday lives.

You've heard the phrase "you are what you eat." Let's take a little stroll to your kitchen and see what exactly it is that you take into your body daily, and what these items may do for your body.

Instructional Procedures:

This assignment contains two parts.  Copy all information below between the lines of asterisks, including the lesson number, revision date and all questions into a word document. 

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

ASSIGNMENT 03.06.01 - REVISION DATE: 8/28/14 (Copy everything between the asterisks.)

PART 1

  • Obtain the original label from any type of non-perishable food Item (get the can or the box). 
  • List all of the Ingredients. There should be at least 7 different ingredients. 
  • Research and explain each of the ingredients.  Make sure you include the purpose for the ingredient in the food and how it helps or hinders your body. (Note: Some items have no nutritive value. You should explain what their purpose is in the product. Why put them in?)
  • Give references for you information. 

PART 2

Being properly hydrated is important for you to stay healthy.  There are several ways to determine how much water you need to drink each day.  Use the following formula to calculate how much water you need to drink each day.  

current weight/2 = how many ounces of water you need to drink each day

1 cup = 8 ounces

For example a person who weighs 130 pounds should drink 65 ounces of water each day.  That's equivalent to 8.125 cups of water each day.

130/2 = 65 ounces  

65 ounces ÷ 8 ounces = 8.125 cups  

  1. How many ounces of water do you need to drink each day?
  2. How many cups of water do you need to drink each day?
