SHOP N C supermarkets

SHOP N C supermarkets. Everything a body needs....

Now with Cafe Na' for your pastry needs...

Actually, These are the elements a body needs. S...H...O...P...N...C... and Ca...Fe... Na...

Your task...find out two biological needs of S, P, Ca, Fe, and Na.  You may (should) work with your table so you only have to do a part of that goal.  I will give you time in class tomorrow to teach each other.

T-test and memory data

Hello class. your assignment for today involves the write-up for the memory experiment. I would like you to produce the following:
Title
Purpose
brief explanation of procedure

Null Hypothesis
Data (reorganize accordingly)
Data analysis (see below)
Conclusion
-think about what this means to you and your success in biology.
Evaluation
-accept or reject the null, explain the stats, reflect on weaknesses and possible ways to resolve those weaknesses in the future.

Data analysis: I would like for you to run basic statistics on these results. I'd like the mean and standard deviation from each group. I also want you to run a t-test on this data. I'll explain t-test at the beginning of class. Don't worry. Its easy. I've found a couple of sites that will be helpful to you.

here's a great site that will do all the work for you.

You'll need a t-table to compare results. You will want to look at the two-tailed data column. (specifically, the 0.05 column) Here's a good site for that.

Thanks and have fun.

Welcome to IB biology!!

Hello new IB students and welcome.

Attention blindness and Owl pellets!

Attention blindness:

Here's the link to the videos that I showed in class (compliments of Nathan Malkin)

 

http://viscog.beckman.illinois.edu/djs_lab/demos.html

People that missed the owl pellet have two things to do:

A.  define what an owl pellet is.  Write a food chain that includes an owl.

B.  Schedule a time to do the owl pellet dissection.  We can do this after school or during 5th period lunch.  If you don;t schedule it, I'll give you an excused grade for the lab, but it will lower your point total (making all other points more valuable)

Get some sleep!!!!!!

The big night.  Remember, at this point sleep is more valuable to you than study time.

One parting shot:  I forgot to cover assessment statement 5.5.3 about classification of plants.  Goto click4biology.info and look at the answer.   Don;t worry it's easy.

Remember, as Benamin Spock says:  

Trust yourself. you know more than you think!

last minute instructions

Pointers for taking the test:

1.  bring a calculator whose memory can be cleared.

2.  bring a small metric ruler.

3.  go to the right place.  Here's a link

Special Prom edition

Prom weekend blog edition!

Here's the great link I promised for Type 2 diabetes.  The animation is really helpful to I'd recommend it to you.

Also, click4biology.info has excellent material for review.

By the way, in the more-than-you-want-to-know catergory:  if a person isn't making enough insulin, what does your body do with all the useless glucose????  Why, pee it out, of course.  Hence the meaning of the term diabetes mellitus
