How does Natural Selection make changes to a population?

2. Watch only if there is spare time available
you tube geologic time scale

3. Reminders
PAST DUE - your rough draft of your RESEARCH report is past due (don’t discuss your experiment at all in this report). It is background research only!
PAST DUE - Ecology Exam Study Guide Review.
PAST DUE - Science Journals
Root Quiz Thursday
Put your Life Has a History Activity in your journal for the next journal check. Make sure you finish the activity.

4. QUIZ Clear your desks of everything Do NOT write on the quiz please
QUIZ
Clear your desks of everything
Do NOT write on the quiz please
Use CAPITAL letters please

5. EcoRegion Project Presentations con’t
Part of your grade will be based on your presentation and your attention during your classmates’ presentations.
Hand me your rubric when you come up to present.

6. Battle of the Beaks- Quick Lab Activity (if not completed on Fri)
I’ll put you into groups of and assign you a table
Each person will choose one of the four beaks on the table: spoon, popsicle stick, forceps, clothespin
Plastic cup for stomach. Stomach has to stay upright and may not be used to assist in catching prey
I’ll say go….and when I say stop…all birds must put down their beaks and stand up to signal they’ve stopped
Count the number of items and record on your data table.
There will be no scissor bills (except 2nd period) since we won’t have any groups of 5. So scratch that entire row out.
First round is worms only, 2nd round is beetles (skittles) only, 3rd round is weevils (life savers) only, 4th round is all
Graph, answer questions and tape in your science journal. List in the table of contents. Be sure to tape it down so that the graph can still be seen. .

7. Patterns of Evolution ppt

8. The Geologic Time Scale (only if there is spare time)
Geologic Time Scale Demonstration
Precambrian
Paleozoic
Mesozoic
Cenozoic
Are the four ERAs you need to know.

9. Evolution = Change over Time (only if there is spare time)
Lizard Activity
Relay race
1st person on the team comes up and draws the lizard as fast as they can. They flip the original lizard over and leave theirs face up.
2nd person comes up once first person sits down and draws their lizard based on the first person’s drawing .
2nd person flips first person’s lizard down and flips theirs up.
3rd person comes up once second person sits down and they draw their lizard based on the second person’s drawing as fast at they can. They flip the second person’s lizard over and they leave their lizard face up.
