Interesting Lab Thursday =]

Bio Day Tomorrow!! Meet in auditorium!
Agenda:
-Hand in UP 4-8
-Natural Selection Lab UP17-19

Homework:
-Read Chapter 16.4 in textbook and fill in the green worksheet due Monday
*You won't be able to find every term in the glossary. So you will need to read the chapter and the write the definition in your own words.
-To get a homework pass you must meet with Mrs.Stein by Tuesday
-The TV ad due 2/28
*We will spend class time researching on Monday
*You can look on UP 2
-UP 17-19(the natural selection lab)

So today we started the period by turning in UP 4-8. Then we looked on UP 12 and 13 to practice our knowledge on Darwin and Lamark. Afterwards, we got into our lab groups and started the natural selection lab (UP 17-19). In this activity two people would work on using a hole puncher to punch out 10 holes out of every piece of construction paper. There were 10 pieces of construction paper and each one was a different color. Therefore there were 100 little circles once we were done. We put the little circles onto a brightly colored cloth. Then there were two predators. The predators would pick 40 circles each, but randomly. Then we would count how many of each color circles were left. For example, you could have 7 reds, 3 blues, 5 green, and 5 yellow. Then we would take each number, multiply it by four then add that number. For example, you had 3 blues. So you would do 3x4=12. Then you would do 12+3=15. That would be the number of circles you would have for the next round. Overall you would do three rounds. If you used your class time wisely you should only have to finish answering some of the questions.

So hope you enjoy tomorrow's bio day!!!

Nick is our Scribe for tomorrow!
