Overview:
In this assignment you will review the hierarchy of an organism and the systems of the body. You will choose one system in the body and complete a chart listing the different parts for each level of organization within this system. After completing the chart, you will answer some discussion questions about your chosen system.
Background Information:
The hierarchy of an organism describes the levels of organization within an organism. These levels of organization are defined by the size and complexity of their parts from smallest to largest. The smallest level of organization of living organisms is a cell. A cell is the most basic unit of structure and function. Cells combine to create tissues. There are 4 types of tissues that make up all of the body:
  • Epithelial tissue forms the interior and exterior surfaces of the body. It creates surfaces for protection, absorption, and excretion.
  • Muscular tissue makes up the organs that have voluntary and involuntary functions and forms the organs responsible for movement.
  • Connective tissue forms binding, supporting, and transporting structures and usually contains collagen for strength.
  • Nervous tissue is made of neurons and glial cells that transport nerve impulses across the body.

Assignment:
On your own sheet of paper, draw and fill out the chart below and then answer the discussion questions.
 
         SYSTEM NAME:
CELL  
TISSUE  
ORGAN  
ORGAN SYSTEM  
ORGANISM  
 
Discussion Questions:
1. What system did you choose? What is the purpose of this system?
2. What are some of the different functions of this system?
3. Where could each tissue type be found? Give an example of each tissue type and where it can be found in the system you chose.
4. Why is this system important to the body?
Submission:
You will submit a completed chart and answers to the discussion questions written in complete sentences. You will be graded based on the rubric on the following page.

Overview:
In this assignment you will be using the scientific method to develop your own experiment. You will not be conducting the experiment but you will develop one based on a hypothesis. You will submit a project containing the needed information outlined under the "Project" section.
Background Information:
The scientific method is a process used by scientists to develop experiments and test hypotheses. This process begins by making observations. The next step is to develop a question based on these observations, such as how something works.
 
Based on the question under investigation, a hypothesis is created. A hypothesis should be a prediction of what happens. It is written in an "if, then" format. An is designed to test a specific hypothesis. A scientific experiment should have an independent variable, dependent variable, and a control group. The independent experiment variable is what is changed in the experiment. The dependent variable is what is measured in the experiment.
 
A control group is a group in which the independent variable undergoes no change. The control group in an experiment serves as a baseline to measure the results of the experiment and can be very useful in isolating unknown factors which may influence the dependent variable.
 
Remember that a good experiment includes multiple repetitions for each experimental group.
Once an experiment has been conducted, all of the data collected is analyzed. Scientists look for trends in the data and use statistical analysis to compare all of the experimental groups. This is then compared to the hypothesis to see if the data does or does not support the hypothesis. Through this method scientists draw conclusions about their hypothesis based on whether or not their experiment was successful.
 
Project:
Below are the instructions for each section of the project. For this assignment you will follow the steps of the scientific method and develop your own experiment.
You will need to include all of the following information:
Topic: Start by deciding what you would like to investigate. Your topic may be related to biology, the environment around you, or some other topic you are interested in.
 
Observations: Make a number of observations related to your topic. If the topic you chose isn't something you can observe around you then you may conduct research about your topic and record any noteworthy information. Include a paragraph describing your observations in your final submission.
 
Questions: Using your observations or research, think about your topic and ask some questions. Think about how it works or why it may behave a certain way. Come up with two or three questions about your topic.
 
Hypothesis: Use the questions you came up with to develop your hypothesis. This is a prediction of what you think will happen and should be able to be tested. A hypothesis is written in an "if, then" format. If this happens, then this will happen.
 
Experiment: Once you develop a hypothesis, think of how it could be tested in an experiment. What would you be testing? What would you measure? Remember that you need a control group. The purpose of this group is to serve as a reference that can be used to compare your experimental results to. This gives you something to compare with all the experimental groups and monitor any change. Record all of the following information about your experiment.
Independent Variable: This is what you are changing in the experiment.
Dependent Variable: This is what you are measuring.
Control Group: This is the group unaffected by the independent variable.
Experimental Groups: These are the groups affected by the independent variable and there should be multiple replications for each group.
Submission:
Be creative with how you present your information. This can be done in a list, in a chart, in paragraph form, or another way. Be sure to include your topic, observations, questions, hypothesis, and the details of your experiment. Be descriptive with your language in each section and use correct grammar.
