pgs 101-105 what goes there????

Just as a review of what goes on pages 101-105

101 -- SSA of objectives for entire year (yes you have to fill out the SSA to get the points)
102 -- printed picture of your dissection animal
103 -- drawing of what you actually saw when you dissected your specimen with observations
104 -- reflection of what you learned and why dissection is important in a Biology class
105 -- reflection of the class as a whole (from August until now)


GRADES are updated as of 4:00 on Thursday.  You can turn in your notebook with revisions through Tuesday (but really the sooner the better!!!)

pgs 102-105 are the PBA (final) for the semester 

Dissection week

Now that the AP test is finished, we are going to take the week to do dissections :)
We have

• crayfish
• perch
• fetal pigs
• rats
• clams 
• grasshoppers

Pick at least 1, research what you should find within the specimen.  Sketch or print a "ideal" specimen, label all the parts.  Complete the dissection, sketch what you actually see.  Write a reflection on the entire process.  You have the week to complete.

pg 100 objectives for the ENTIRE class :)

Another booklet to go on pg 100 (or 101 so that it opens with the book) that gives you all of the objectives in one place to help in your studying this weekend ;)

pgs 96-97 Chi Squared Genetics

These two pages go on 96-97

pgs 94-95 Chi Square Ecology

These two pages go on 94-95

pgs 92-93 more candy chi square stuff

Leave these pages for more analysis of the gummi bear chi square data.

pg 91 Chi Squared data

Procedure:

1) Look into the bag and determine how many colors are present and write them into Table 1

2) Without counting, estimate the number (percentage out of 100%) of each color and write them into Table 1 under "Percentage Expected"

3) Sort the candy and write down the number of each color into Table 1 under "Number Observed"

4) Complete the table by determining the total number of candies and number expected columns

Color of Candy	Percentage Estimate	Number Observed	Number Expected (total # of candy x percentage estimate)
	Total # of candies =

pg 90 Chi Squared

This information should be on page 90

Chi Square (Χ²) Modeling using Candy

The Chi Square test is often used in science to determine if data you observe from an experiment is close enough to the predicted data.  In genetics, for instance, you might expect to get a 3:1 ratio if you crossed two heterozygous tall plants (Tt x Tt).  Calculating the Χ² values help you determine whether the results follow the prediction and if the variations from the exact ratio are due to random chance.  It’s the question of “how close is close enough?” If the numbers differ greatly from your expected results, then it’s possible that other factors may be influencing your results.

A chi square analysis requires a scientist to propose a null hypothesis and an alternative hypothesis.  IN statistics, the only way of supporting your hypothesis is to refute the null hypothesis.  IN other words, rather than trying to prove your idea right, you must show that the other idea (hypothesis)is likely to be wrong.  That is your NULL hypothesis.

Chi square values are used to show that the likelihood that the outcome is due to random chance is very unlikely.  An alternative hypothesis can never be proven, data can only reject or fail to reject the null hypothesis.

pgs 86-89 Notes from your plan on page 84

Page 84 should have the two modules you picked from education portal and also a plan for learning the information within.  Pages 86-89 are where you can write or tape in notes that you have taken from those two modules.
