Math - We are now working on coordinate geometry (four quadrants). eg. How to label a point (x, y) both positive and negative.

We are creating our own coordinate geometry picture and then writing out coordinates to see if someone else can draw our design. Due next Thursday.


Language Arts - We are finishing up our Eco-inventions, Think Green drawings and readings about Paper Houses and Flying Cars.

topics for next week are: contact lens T.V. and Green T.V. show (24).

Most classes are working on the topic of Fluids in Science.
Here are some good web sites to help you research your topic.

Fluids
The Fundamentals of Fluids - from bj's MST web site, an excellent resource developed by B. Jackson of Camilla Senior School in Mississauga to support her grade 8 students.

Submarines: How They Work - Archimedes' Principle - an interactive demonstration
"Voyage of Doom" - Buoyancy Question - from NOVA online (PBS)
How Hydraulic Machines Work - from the How Stuff Works web site
Buoyant Force in Liquids This Java applet shows a simple experiment concerning the buoyancy in a liquid: A solid body hanging from a spring balance is dipped into a liquid (by dragging the mouse!). In this case the measured force, which is equal to the difference of weight and buoyant force, is reduced.


Here is the copy of the outline to help you organize your project.
We will be doing some research in Language Class (help to organize your non-fiction work).

Fluids in Natural Systems

Choose a Topic (circle it):

Human heart vs. Water pump

Fish swim bladder vs. ballast tank in a submarine

Spider’s legs vs. hydraulic arm

Valves in human circulatory system vs. valves in a car’s engine

What do you know about each system? How are they similar? How are they different?

Also we decided to have a bake sale for Earth Day (April 22). We are looking for appropriate recipes so we can make some tasty treats.

No school Friday due to Parent-teacher interviews.
