California Life Science, Chapter 7: Changes Over Time

So much to do and so little time:

California State Standards covered in the chapter-

• 7.3 Biological evolution accounts for the diversity of species developed through gradual processes over many generations.

1. Students know both genetic variation and environment factors are causes of evolution and diversity of organisms.


2. Students know the reasoning used by Charles Darwin in reaching his conclusions that natural selection is the mechanism of evolution.


3. Students know how independent lines of evidence from geology, fossils, and comparative anatomy provide the bases for the laws of evolution.


4. Students know how to construct a simple branching diagram to classify living groups of organisms by shared derived characteristics and how to expand the diagram to include fossil organisms.


5. Students know that extinction of a species occurs when the environment changes and the adaptive characteristics of a species are insufficient for its survival.
   

• 7.4 Evidence form rocks allows us to understand the evolution of life on Earth.

1. Students know fossils provide evidence of how life and environmental conditions have changed.

Update for 10-4-07 to 10-8-07

Due to the large number of students that did not do their homework I will change the content of the assignments slightly.

For 10-04 and 10-05 (Thursday/Friday) the new assignments are:

Read and take Cornell notes on pages 88-95.
Reading Checkpoints: pages 89, 92, & 94.
RNTG 58 (only).

The assessment on the bottom of page 95 is postponed while the students learn how to take good Cornell notes and complete their homework.

In class we will cover the following:

• Complete the movie--"The Inside of a Cell"
• View the DVD video--"Cell structures" (from Prentice-Hall)
• Listen to page 88 being read by the computer and then take Cornell notes with full prompts from Mr. Thorne.
• continue this on page 89.
• Pages 90-91, the drawings: Copy the drawings, label them in English and Spanish. Write a short description in English or Spanish. Double credit for bi-lingual.
• Pages 92 and on...complete as much as possible in class with the rest due on Monday, 10/08/07.
