You will research the disorder I gave to you in class and…

1. Give a 5-8 minute presentation – the type of presentation is up to you – it can be a lecture, ppt, video, etc… but should include pictures as appropriate. Make it interesting! Be sure to include information about your condition such as…

What is it?
What are the signs and symptoms?
How do we detect/diagnose it? (genetic, imaging, blood test, visually, etc…)
How do we treat it?
What is the prognosis if untreated?  treated?

2. Write a 5 question (multiple choice) quiz (per disease). Include the answers and make sure that your classmates will be able to answer those questions after your presentation as they may be on the upcoming test.

3. Hand in a summary (1 page or less) of your disorder and your quiz (with distractors and the correct answers noted!).

Due: Wednesday/Thursday, 12/3/14 or 12/4/14

Nutrition and Why We Need to Eat 2014

Complete the spreadsheet that was shared with you in your Google Drive titled, “Why Do We Need To Eat”.  The document is shared with each member of your table group so you will complete it together.

  • For the ‘Good Sources’ column name 3 good food sources for that item
  • For the ‘Named Examples’ column
    • Give 3 examples each of named carbohydrates, proteins and lipids found in the body.
    • For the vitamins, give the name of the vitamin if it has one.  If it does not have one then just leave it blank.  For example, Vitamin B1 is also called thiamine.
  • For the ‘Disorders’ columns – name the disorder and give a few symptoms/problems the person will have as a result.  Some items will not have an associated problem if you take too much – if that is the case then type ‘none’ in that box.
  • Nothing will go in the two rows that are labeled ‘Vitamins’ or ‘Minerals’ – they are just header rows for the items beneath them.

Due: G & H period: Tuesday, 11/18/14; D period: Wednesday, 11/19/14

You should complete the analysis of the alien dataset as instructed in the Google document. You can determine the appropriate statistical test and graph to use for each question at home and then come to my room during activity period or your study hall to use the MyStat software.  You may use the Google Sheet I shared entitled Statistical Tests and MyStat Student.  You are assigned to work with one partner – you may not work with anyone else.  Asking other students besides your partner for help/answers will be considered cheating and greatly damage your grade.  If you need help, ask your partner and then ask me.

The retakes for the torso practical will be on Thursday, 10/30/14 after school.  The rules will be as follows:

  • Anyone can choose to retake the practical.
  • You can earn a full 100%.
  • Your second grade will replace your first grade.
  • You can do WORSE.
  • Let me repeat – your grade can go DOWN if you choose to retake the practical – your new grade will replace your first grade whether it is better or worse!  So choose wisely.
  • You will lay out the pieces on the table in the order you wish.
  • You may hold one piece in one hand and touch some part of the model with your other hand to orient yourself.
  • You will close your eyes and complete the practical with your eyes closed.
  • If you open your eyes, you get a zero.
  • If you knock pieces on the floor, that will be a significant problem for you, so don’t do that.
  • You will have 2 minutes and 15 seconds to complete the practical.

Test next class using Google Sheets to calculate various descriptive statistics and create associated graphs. I created a practice test and shared it in your Google ISR folder.

You must also finish all of the remaining Gettysburg random sampling activities 1, 2, and 3, as well as the problem set questions. This is due before the beginning of the next class.

Genetics Background 2014

Since we have a diverse group of students, ranging from sophomores to seniors and starting biology to completed AP biology, it is important that we all have a fundamental background in genetics to start building from.  So each of you should go to the DNA From the Beginning website and complete items 1-24.  Items 1-14 are under the heading “Classical Genetics” and items 15-24 are under the heading “Molecules of Genetics”.  You should see these on the right side of the browser window.  For each item you should, at least, view the ‘Concept’, go through the ‘Animation’ and complete the ‘Problem’ as a self-test.  You can look at more for each if you want (e.g. Gallery, Video, etc…), but the Concept, Animation and Problem should be good enough for most of them.  This is a considerable amount of material so you should do a little bit each night or you will be overwhelmed at the end.

STEM Chapter 9

You should read chapter 9 in your STEM book on inferential statistics and write down any important points in your notebook.  Remember – if you were running an experiment and could test everyone in the population the you would know your answer.  Unfortunately, this is often not possible.  So instead we test a sample of the population and we hope to be able to infer something about the whole population from the sample.  But since there is always variability in the sample we choose, it can be difficult to know for sure if any differences we are seeing between our treatment and control groups are due to the treatment (independent variable) we applied or just due to chance.  If we do see a difference between the experimental group and the treatment group, we can use mathematical tests to tell us the probability that the difference we are seeing is due to chance rather than due to our treatment.  If the probability due to chance is sufficiently low, then we can start to suspect that our treatment is what actually made the difference.  If the probability due to chance is too high, then our treatment was likely not the thing that made a difference.  Chapter 9 discusses various statistical tests you can use to calculate this probability due to chance for various experiments and types of data.  It also discusses what probability due to chance is considered too high to support your hypothesis that your treatment made a difference.
