Animal of the Day:

#7 was a Blobfish.

This animal is the class, Osteichthyes

The blobfish is native to Australia

Found at the depths where the pressure is 30 times higher than at sea level

Homework:

• Finish yellow "Comparison of Vertebrate" chart
• Tv add due 2/28
• Study for test 3/1

The next scribe is Lucija! :)

Shortened Tuesday!

Agenda:

• Get second stamp for unit packet 39-46
• Take notes on genetic disorders
• Assign homework: Unit packet 47-52
• Assign extra practice pages in unit packet: 53-56 (**optional)

Because all the classes were shortened, we had little time to do much in class. We did notes and then had some time to continue our homework.

Notes:

Microscope Tuesdays!

Last night, the only homework we had was to work on our lab write-ups for the rip-o-meter lab. Mrs. Stein changed the due date from September 10th, to September 8th. The write up must be typed. If it is not typed then you will receive a zero for the assignment. If you need help the write up, there is a format page in our unit packet, pages 31 and 32. Other reminders that where on the board where: Our first quiz is Thursday the, 2nd. The unit packet, pages 33-37 are also due on Thursday. Don’t forget to visit Mrs. Stein for your homework pass!


Once we went over the reminders, we went over the homework. Mrs. Stein said that we must use our own words when doing our homework. The reason for this is that she wants us to prove to her that we are learning something from the lesson and not just copying what the book says.


When we where done with that, she assigned a new lab for when we where done with the rip-o-meter lab. The lab is to examine different materials under a compound microscope. The purpose of this lab is to become more familiar with this particular microscope. Mrs. Stein taught us how to properly hold it, which is always by the top handle. She also explained that when you first look at something through the microscope you start on the lowest power, which in this case is 4x. If you have any questions about the lab, pages 33-37 in our unit packet explain the lab.

Don’t forget to bring in your goggles and your workbook to class this week!
