The following post contains a link to the latest set of Cornell Notes in Mr. Hatfield's classes.  These cover the divisions of the nervous system, the basics concerning the endocrine system which it interacts with, and the structure and function of the neuron, the type of cell that makes up most of the tissues in the nervous system.

Students in Mr. Hatfield's classes also received a 100-point Project in class today called 'Back to the Future' that brings many of these topics together.   Students will complete this Project by addressing the questions in a manner that relates the nervous and endocrine system to specific California State Standards.  

Students' answers should be according to the RA Guide, in that all responses are complete sentences, that refer to the original question, and show evidence of reasoning.

Students were shown the above 22-minute video segment during class on Tuesday, Feb. 25th.  

The video describes some of the events that take place in the development of a human infant's brain.   There was a worksheet based on this video, collected on the same day in class.   However, because there was a substitute, there may have been some confusion on what the expectation was.  And, of course, some students may not have been present during Tuesday's class.

So, to make sure that every student has an opportunity to complete the assignment and earn points in Mr. Hatfield's Biology classes, I am making both the worksheet and the video available through the class blog.   First, here is the video, broken into a pair of segments:

Students who are interested in watching other videos in this series can find them on the following YouTube channel:

Finally, for those who need a copy of the worksheet, it is available HERE.

Here are the notes on Human Body Systems that were completed during class on Friday, Feb. 21st.

Use these to make sure your Cornell Notes are complete!

Today, students received a new syllabus for their new unit on "The Nervous System and the Neuron".   This will be a relatively-short unit.   There will be a 100-point Project due on Tuesday, March 4th.   The same day, after school, there will be a Study Session to prepare for the Unit Test on the following day.   Students who score higher on this test than the previous unit test will have their scores for the first unit test raised, so it's important that students plan ahead to take advantage of these opportunities.

Here's the syllabus:

Here is the (brief) Power Point discussing, and giving examples of some basic principles of probability. This is, of course, math....but an essential tool, also, for doing science.

Also, here's the short Power Point notes on 'Chromosomes and Meiosis'.

Our current unit on Mendelian Genetics and Meiosis was originally scheduled to have conclude today (Friday, Feb. 7th).   Unfortunately, Mr. Hatfield's commitments to the Fresno Teachers Association's Bargaining Team have led to occasional unscheduled (but also unavoidable) absences.   Today's test has been rescheduled, therefore, for Friday, Feb. 14th.

Students will be provided a Study Guide on Tuesday, Feb. 11th.  Because of Mr. Hatfield's commitments, there will be NO After-School Study Session prior to the test.  Mr. Hatfield will be available in his room at noon on both Tuesday and Wednesday to answer any questions based on the Study Guide, but he will NOT be available after school due to FTA commitments.

Tuesday, Feb. 11th is ALSO when student's 70-point Project ("Mendelian Genetics Booklet") is also due: 

Students who do not provide the Booklet prior to the end of school on Tuesday can expect a home contact.   Mr. Hatfield would be gravely concerned about any student who is unable to finish the Booklet after four days, because that student will obviously be choosing not to prepare for next Friday's exam, and thus CHOOSING TO FAIL.   Don't do that, students!

Finally, to help students continue their study of Meiosis, Mr. Hatfield is making the PBS video shown in class ("Life's Greatest Miracle") available on-line, here:

The lecture notes for the present unit on Genetics is available at this link. Students have been assigned a 70-point Project, a "Mendelian Genetics" booklet. They may find the notes, as well as their text (Chapter 11) are very helpful in completing this project, which is due on Friday, Feb. 7th. They have also received a Lecture Guide in Mendelian Genetics that covers this material, which will be due on Thursday.

Students who fail to hand in their BOOKLET by Monday, Feb. 10th, may have the home contacted.
