Peppered Moth Selection
Overview:
This activity will simulate what occurred in the population of peppered moths during the -trial Revolution and you will answer questions and make inferences about it.
 
Background Information:
The Industrial Revolution was a time in Europe when there was a massive increase in industry and factories. Methods of production shifted from handicraft to machine, along with the use of new materials like iron and steel, and new energies like coal, steam engines, electricity, and combustion engines. The large number of new factories put out large quantities of smoke and created a dramatic rise in pollution.
 
The Peppered Moth population was significantly affected by the Industrial Revolution. Prior to this time period peppered moths used to be white and lightly colored and were only rarely peppered or black in color. These moths lived in a forest full of Aspen trees with light colored bark, and their light coloring allowed them to camouflage for protection. After the Industrial Revolution, scientists noticed there was a drastic increase in the number of peppered and black moths and a decrease in the number of white moths. The Industrial Revolution caused a change in the habitat of the peppered moths, and the makeup of their population shifted as a result. Scientists believe that this is due to natural selection.
 
Assignment:
For this assignment you will count the number of each type of moth in a set of images and then make inferences about what you notice. You will answer questions about the images and the possible causes of the shift in coloration of the peppered moth.
 
Submission:
Answer the questions for each image as well as the discussion questions and submit your work. A grading rubric is included below the questions for this assignment.
 
Image Questions: Answer the following questions for each image.
How many white/light moths do you see? How many peppered/dark moths can you see?
 
Discussion Questions:
1. Which image represents before the Industrial Revolution?
2. Which image represents after the Industrial Revolution?
3. In Image 1, which moths are more easily seen?
4. In Image 2, which moths are more easily seen?
5. What do you think happened to the Peppered moth population?
6. What about the Industrial Revolution caused the shift in coloration?

Present a Persuasive Speech
Student Resource
Preparation: Presenting a Persuasive Speech
When you present a persuasive speech, keep in mind the elements of good public speaking, listed below. Remember, you will be presenting, not reading, your speech.
As you are touching up your speech to get it ready to present, you may want to add some visuals or multi-media as appropriate. Be aware that any media you use should clarify and enhance - not overpower - your speech.
 
Elements of Good Persuasive Speech Delivery
Eye contact - If the audience is small and close, look them in the eyes; if they are not, at least look up at them.
Gestures - Mark your key points with hand or body emphasis.
Change in Volume - Emphasize important points with an increase in volume.
Change in Pitch - Voice Inflections help engage audience.
Cadence - The rhythm and speed you establish in your speech pull your audience along. Sometimes a break in cadence is very compelling.
Posture - Avoid nervous habits - e.g., playing with hair or note cards, drumming on the podium, swaying back and forth.
 
Assignment: Listen and Evaluate
Listen to a public speech. This could be a speech covered in the news, such as a political speech, a presentation at a conference, a new product announcement, etc. While you are listening, evaluate the speaker according to the criteria in the table below. Note that you are evaluating the speaker's credibility, bias, purpose, and priorities - not the speaker's delivery.

Scientific Method Project

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 experiment is designed to test a specific hypothesis. A scientific experiment should have an independent variable, dependent variable, and a control group. The independent 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.
 
You will submit a document or presentation with the required information for each part of the scientific method. Label each part and make sure the information is complete. You only need to include the parts of the scientific method included under "Project."

"Heart| We will forget him!"
by Emily Dickinson
Heart We will forget him!
You and I-tonight!
You may forget the warmth he gave-
I will forget the light!
When you have done, pray tell me
 
That I may straight begin!
Haste! lest while you're lagging
I remember him!
