Team 7B Science

Homework:
 - Study for your test!
 - Read pages 119-122. Bring any questions with you to class tomorrow.

Today in class we:
 - Took notes on index fossils (available online!)
 - Did an activity to see what index fossils can reveal about earth's layers.

Homework:
- Complete the review and reinforce worksheet (#4.2). Do not answer question 4. Sorry, I can't post a copy of the worksheet online.
- Review your notes
- Work on your study guide

Today in class we:
 - Reviewed intrusions and extrusions.
 - Reviewed how to identify intrusions and extrusions.
 - Reviewed the principles of inclusion and cross cutting relationships
 - Took notes on faults and types of unconformities
 - Practiced identifying unconformities
 - Practiced finding the relative age of layers containing faults, folds, intrusions, and unconformities.

Homework:
 - Read pages 113-116 (stop at Using Fossils)

Today in class we:
 - Discussed why sedimentary rocks are used for relative age
 - Discussed the law of superposition
 - Discussed how earth's plates disrupt horizontal rock layers
 - Discussed anticlines and synclines and 

Homework:
 - No homework. :)

Today in class we:
 - Reviewed our fossils notes by answer questions
 - Started notes on relative age.

Your final grades for quarter two have been posted. Good job this quarter!

Homework:
 - Read pages 110-112
 - Answer question #9 on the Fossils Worksheet (we did all the other questions on it and went over the answers last week. Title is Section 4-1 Fossils)

Homework:
 - Review observations and inferences. Think about the inferences you can make from looking at dinosaur footprints (or any other trace fossil). Here were the observations. You should have an inference for each of these:
Qualitative:
1. Footprints have sharp toes.
2. Footprints have rounded toes.
3. The sets footprints are not the same.
4. The footprints intersect.
5. A set of footprints changes directions.
6. A set of footprints had shadows within it; the others do not.
7. A set of footprints leaves where the two sets intersected, the others do not.
Quantitative:
1. Footprints B have a stride 3-4mm (scaled) larger than footprints A.
2. Footprints B measure 9mm (scaled) in length, footprints A measure 4mm.
3. Footprints B stride increased from 3-4mm to 12-15mm. Footprints A remained unchanged.

Today in class we:
 - Received our unit four tests back
 - Finished our footprint observations and practiced making inferences

Quarter two grades will be posted on the online grade book by next Friday. My goal is to have your final grades ready at the end of next week. I will finish grading your tests this weekend and have your scores posted by Sunday night. You're welcome to calculate your grade using the grade calculator. Please remember that is not your official final grade. It can change!

Homework:
 - Finish writing 3 qualitative observations about the footprints.

Today in class we:
 - Observed and classified four types of fossils
 - Took notes on trace fossils
 - Observed and made observations on dinosaur footprints.

Homework:
 - Answer research questions 1 and 2 on your lab sheet. (Most periods did this in class.)

Today in class we:
 - Checked in last night's homework
 - Reviewed original remains fossils
 - Discussed petrified, mold and cast, and carbon film fossils
