rolling dice lab
The following is instruction for the dice lab that we started on Thursday.
Rolling dice – craps, gambling, set up so house wins
With 2 (6 sided) dice, what is the chance of rolling a 2,3,4,5,6,7,8,9,10,11,or 12
1. Observations – describe the dice, is there an equal chance of landing on any side? Make at least 10 observations.
2. Hypothesis – pick a number between 1 and 13 and using logic, make a prediction about what percentage of the time you will get a sum of that number when you roll your two dice. How many ways can you role your sum. Now you should be able to make a prediction about how many times your # will come up if you roll the dice 100 times.
3. Experiment – design an experimental plan, write your plans in numbered steps. How will you record your results? Execute the experiment (do the experiment) Record your results and any relevant observations.
4. Analysis – what does your data mean? Explain any calculations you make.
5. Conclusions – What was the measured percentage that you actually came up with? Is this different than your hypothesis? Is it close to your hypothesis or not? Based on the results, do you accept or reject your hyothesis?
6. Repeat – could anything be gained by repeating the experiment? Would you do anything differently? Are there any modifications or related experiments that you can think of that would be interesting?
7. Report – write a lab report. This should contain 6 sections corresponding to each of the above parts of the scientific method. Each section should be in paragraph format with complete sentences. The one exception to this rule is the experimental section which can have the steps listed in order.

week 10
This week we are continuing to work on chapter 2, the scientific method, different types of models and decision making. On Thursday we will have a quiz on the second section of chapter 2. We are now in the 4th week of the worm lab and will continue it for a few more weeks.

week 9
This week we are working on outlining chapter 2. The outline is due on Wednesday the 14th.
We will have a quiz on the 14th as well. It will be over the first section of chapter 2 and will be open note.
I will not be there on Wednesday or next Monday but expect everyone to behave for the substitute.
Wednesday we are also taking observations of the worms.

Extra Credit opportunity
Each student can bring a news article related to Environmental Science. This means any article related to the relationship of people to their environment. This can be from the paper, magazines, or the internet. The length of the article should be between 150 and 400 words. You get 25 points credit if:
you are the first person to bring the article (no duplicates with other students)

You can do one of these assignments per 9 weeks.

Ecological Footprint paper
Ecological Footprint Homework Assignment (100 point assignment)
due Friday, Oct 9th. If you want it to help your grade this quarter it must be turned in on time.
This is an important assignment. It is worth the same amount as an exam. It is worth 4 regular homework assignments. I will be available in the library Tuesday after school if anyone has questions, needs help, or needs to use the computers.
On a computer with internet access, go to the following site to calculate your ecological footprint.
http://www.myfootprint.org/#
Take the quiz, answering all the detailed questions.
You may need to ask your parents to help answer a few questions.
After taking the quiz, record the results. Include the following:
How many earths would we need if everyone lived the way you do?
What was your carbon footprint?
What was your food footprint?
What was your housing footprint?
What was your goods and services footprint?
How did these compare to the average for your country?
After you take the quiz, make a list five things you could change to minimize your footprint.
Next, click on the box labeled “Reduce your footprint” to see their suggestions.
Take the quiz again as if you have made these 5 changes to see how it would affect your score.
Now write a 1 page paper (at least 300 words) about your ecological footprint.
Some questions you might want to consider when writing your paper are:
Were you surprised by your score?
How do you feel about your score?
Is your lifestyle sustainable?
If everyone on earth tried to lived the way you do what would happen?
How would you like to live in another country where people use much fewer resources?
Is it fair that we use so many resources?
Do you plan on making any lifestyle changes?
When you grow up, do you think you will be more of less efficient than your parents?
Explain.
Extra credit: If you are still interested, you can check out other ecological footprint sites and compare them to the one above. Be sure to record your scores and write a short (100 word ) comparison. Below are a couple of other sites.

On Tuesday we will discuss and work on Ecological Footprint assignment.
On Wednesday we will have a short quiz on chapter 1, section 2 which will be open note so everyone should bring their outlines and notes to class.
Homework assignment will be to figure out your ecological footprint and write a 1 page paper on what resources you use that contribute to it and what you could do to reduce it.
