 * Wed. May 4**


 * Thurs. May 5**






 * Fri. May 6**

first half of class - go over review packet second half of class - do multiple choice problems in EOC study book (the "turtle book")
 * Mon. May 9 - Wed. May 25**
 * EOC REVIEW each day**

Practice EOC test is due. Bring to class and I will grade it right away. Begin doing test corrections.
 * Mon. May 16**

Here are two resources that you can print out about blood typing. Examples of blood type punnet squares are given.





EOC Review - complete Goal 3
 * Tues. May 17 - Wed. May 18**

Fire drill at beginning of period. Students worked on Chapter 4 in "Turtle Book" Write down definitions of all term in **bold.** Do all sample questions in Chapter 4 of "Turtle Book." Over the weekend, students will do the Pre-Test and the Post-Test in the "Turtle Book." Answers can be found on the EOC review link (at the bottom of the Biology home page).
 * Thurs, May 19**
 * S**tudents formed study groups for the weekend in order to share the limited number of "Turtle Books."

HERE ARE THE STUDY GROUPS FOR THE WEEKEND:

Madison & Adebayo Ian and Jonah William and Nate Kevin and Daniel Justin and Josh Oriana and Anna Laura A. and Justine Shyam and Eli Annie and Laura S. Shelby, Lyndsey and Jefferson Gabby and Caroline

The following students will work on their own: Katherine, Rachel, Chris H-T, Andrew, Crescentia

Do all of the questions in each of Goals 2-5. Answers are at the end of each question set. Check your answers and your understanding of the ones that were incorrect. []
 * Fri. May 20**

Here's a neat program from New South Wales, Australia. You can create your own biology test, take the test and review your answers. []

Punnet Square and Pedigree practice []
 * Mon. May 23**

[]

[]

Some tests automatically give you feedback, while others require recording answers and checking with key at end of test. Do both types. Write down notes for incorrect responses if necessary. Ask me for assistance. Remember - WORK QUIETLY AND USE TIME WISELY Take notes on the same sheet you signed in class before going to the lab. You may use more sheets, just staple to the original one.
 * Tues. May 24**
 * //More multiple choice practice//**
 * Instructions: WORK QUIETLY AND USE YOUR TIME WISELY; DO NOT CAUSE DISRUPTIONS.**
