Julia Reflection 4th Quarter

First of all, I would like to say that I enjoyed blogging throughout the last two quarters. I actually liked to write scribe posts and summarize what happened during class. Being able to provide information about class to people, and knowing that they learned at least one fact about Science, made me feel very content about my work. However, I didn't really like using Blogger.com because I have had difficulties with uploading pictures to the blog, but in the end I managed to solve these problems. I found the writing part of the scribe post rather easy, but adjusting the font and color was kind of hard in some aspects. I do think that using technology during class was a wise choice; our blogs could be shared to a huge group of people and we were also being Eco Friendly at the same time. Although some parts of technology didn't come easy for me, I do think blogging was very worthwhile and enjoyable.

Hello 7th Grade

During class on Friday we handed in our Cell Project that was due on Friday. After that we went over our notes on Section 1: Body Organization and Homeostasis and Section 2: The Skeletal System. We discussed some topics regarding of what we are learning.

We also filled out the diagram concerning the different bones in the Skeletal System. We labeled the different parts of the bones in the Skeletal System.

If you follow this link ( http://www.encognitive.com/images/skeletal-system.jpg ) it will take you to a picture of a skeletal system with its bones labeled. It will help you fill out the diagram.

For those who weren't here, these are some important notes (NOT ALL) we discussed during class.

Section 1: Body Organization and Homeostasis

- Homeostasis: Process of internal environment keeping balanced and stable. (Not being affected by outside environment)

Example of Homeostasis: When the internal body temperature is close to 37°C despite the temperature of the air around you. (Except when you're sick.)

Things that disrupts Homeostasis: Stress, Illnesses (Cold etc...)

Section 2: The Skeletal System

- 5 Major Functions of the Skeletal System

a) Provides shape and support

b) Enables movement

c) Protects Organs

d) Produces blood cells

e) Stores minerals/material until they are used

Joint: A place where two bones meet. Allows bones to move in different ways.

Two kinds of joints: Immovable & Movable

Immovable Joints: Allows little/no movement. Ex. Joints at skulls.

Movable Joints: Allow body to make wide range of movement.

Ligaments: Connective tissues. Hold bones in movable joints.

Cartilage: Connective tissues. Flexible than the bone. Cover ends of bones. Keeps from bones rubbing against each other.

Four ways of how joints work

- Hinge Joints: Allow forward/ backward motion. Ex. Elbow

- Ball-and-Socket Joints: Allow greatest range of motion. Ex. Joint in shoulder

- Pivot Joint: Allows one bone to rotate around another. Ex. Neck

- Gliding Joint: Allows one bone to slide over another. Ex. Wrist & Ankle.

Osteoporosis: Condition where the bones lose minerals and break easily. Occurs when the bones lack calcium.

The picture on the left shows how a normal bone looks like. The picture on the right shows a bone with Osteoporosis.

During our discussions at the end of class we were discussing relationship science has to the world. We were talking about where (in the world) we think Osteoporosis occurs the most. Some people thought it was China because of the population and the number of Asians who are lactose intolerant. Others thought is was Africa because of economic state and how they are not able to afford milk, which contains an abundance of calcium. Ms. D told us that people in Africa obtains calcium by putting calcium in their bread! We ended our class with the discussion.

Homework!!!

- Email Ms.D about Bodies Revealed (Due Tuesday, March 25th)

- Write Notes for Chapter 3

- Comment to 6th/7th/8th Blog

You could go on Moodle (http://zagreb.ceesa.net/course/view.php?id=105) to check more information about the following weeks!

Remember to bring COLOR PENCILS to class on Tuesday.

Next scribe is ANTONIA!!!

Julia's End of the Quarter Reflection

This past 4 weeks of the 3rd quarter was rather exciting and new. About a month ago I came back to AISZ again and found that many changes occured while I was gone. I found out that we had something called blogs! It was definitely new for me. One of the hardest thing about the blog was that is was kind of hard to get use to it and it was rather hard to get around the blog. After I got used to it I realized the blog was really useful. The blog was helpful when I wasn't at school. I was still able to know what happened during class. Also the comments helped me a lot, so next time I know what to fix when writing my next blog!! Overall I enjoyed using the blog.

March 19th Class

Today in class we finally got our Super Heroes back!!!! Some of us posted pictures of our Super Heroes on the bulletin board right outside the Science classroom.

After doing that we went over the Work & Power Math 2 Problems we had for homework.

Some of the questions we did were.....

Question 2.

If 562.3 J of work are used to move a smart car 15.1m, what is the amount of force applied to that smart car?

Formula: W=Fd or F= W/d

Plug: F= 562.3 J/15.1 m

Chug: F= 37.24N

While going over our homework, we also did a quick review on our units and formulas for our quiz on Tuesday.

Here are the units and formulas for Work and Power!

Work = Force x Distance

Power = Work/Time

Work = J (joule)

Force = N (Newton)

Distance = m (meter)

Time = s (second)

Power = W (Watts)

After doing that we went to the computer lab to test another Gizmo. This time was also about inclined planes, however it was harder from what we did last time. We were changing the angle of the inclined plane and the weight of the object falling down the inclined plane to find more about the inclined plane.

So this is what we did in class on Friday. And.........

DON'T FORGET TO STUDY FOR THE QUIZ!!!!!

Study Textbook 108-118, 124-133, also practice solving the worksheet.

If you have questions you should ask Ms.D on Monday.

Be sure to bring your CALCULATOR on the Tuesday.

The next person to scribe is...................
