Biology, 1st – 4th periods
Mrs. Sabo
FRIDAY
STUDENT OBJECTIVE:
- Students will understand the following ideas (chapter objectives)
- That populations of organisms change across time
- ***That it takes billions f years for the evolutionary process to create the great diversity of life on Earth.
- Evidence for biological evolution exists in the fossil record and in biological characteristics such embryological development and genetics
- Natural selection is a major mechanism of biological evolution
- Today’s Objectives:
- Students will understand how scientists use evidence to create inferences.
- Students will understand the history of the Earth based on geological evidence.
CLASS OUTLINE:
Activity: Modeling the Earth’s History - pg. 36 – 38
Students are given a handout that shows the major geological and biological events that have occurred during earth’s history. Students will create a time line in their group of 4 that will show Geological events in one color and Biological events in another color to show not only when events happened, but how they may/may not be related to each other.
After completion of the time line, students will answer Analysis questions on page 37-38 #1-3.
ASSIGNMENT:
Use the time line that you just created to answer the following questions with your team mates. Record your answers in your journal.
- Describe 5 patterns that you see in the time line. For example, describe a relationship between geological and biological events or a relationship between plant and animal events.
- Is it likely that these patterns occurred separately or do you think they might be related? Explain your reasoning by using 1 or 2 of your examples above.
- What did the time line (a model) help you understand about the earth’s history?
HOMEWORK:
- Work on your independent research project (if not finished and turned in to me today).
- Work on your presentation (for those who have signed up for presentation times today).
- Finish above questions 1-3 if you have not done so already.
