Life Systems - 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.

An Introduction to the Cell - a multimedia tutorial from McGraw Hill that addresses many of the basic concepts of the Gr. 8 curriculum. (It may take a while for the file to download and start playing.)

CELLS alive! 

Cells and Simple Cell Transport - from BBC Education

The Virtual Cell Web Page

Human Body - another excellent interactive site from the BBC

The Virtual Body Interactive presentations on the Brain, Digestive System, Heart and Skeleton. (requires Shockwave plug-in)

Cell Division and Cancer - Find out about cell structure, division, mitosis and how, when this goes wrong, it can lead to cancer.
 

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.
 

Optics

  -based student learning activities  Investigating Optics ; Light and Optics, Optics for Kids, Refraction of Light

Light and Optics - 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.

Science, Optics & You - Java-based interactive tutorials designed for elementary grade students

Electromagnetic Radiation Explore the physics underlying X-rays, light, and other kinds of electromagnetic radiation. This site quickly goes beyond the level required for this grade but it is a good source of information and would provide extra details for those students who wish to pursue the topic in greater depth.

Optics for Kids

Refraction of Light Demonstration - this page uses a Java applet to allows students to experiment with refraction.

Reflection/Refraction - an interactive Java applet that shows the physics behind a beam of light impinging at an angle on a smooth/rough surface

The Physics of Amusement Parks - learn about the forces of falling, floating and turning by studying the rides at amusement parks - from the Japan  Science and Technology Corporation

Amusement Park Physics   How do physics laws affect amusement park ride design? In this exhibit, you'll have a chance to find out by designing your own roller coaster. Plan it carefully--it has to pass a safety inspection. You can also experiment with bumper car collisions.

Science of Cycling    Sections on The Wheel, Drives & Gears, Frames & Materials, Braking & Steering, Aerodynamics, and Human Power

The Sydenham River - Strathroy Middlesex Museum has put together a virtual exhibition on the history, geology and biology of the Sydenham River Watershed in southwestern Ontario. The site was written specifically for the Ontario curriculum, and contains a Teacher’s Corner that shows educators how the various vignettes allude to the curriculum.      English and French

The Watershed Game   Would you make the best decisions in managing a watershed? Examine the issues in each area of the watershed, then see the impacts of your choices!

Flood! - NOVA Online

Water in the City   In one kitchen, in one apartment, in one building, on one block, in one neighborhood, of one city, a young man goes to the faucet and fills a kettle with water. At the very same instant, thousands of other people in that same city may also be tapping into the water supply. How is it possible?

Water Science for Schools  The U.S. Geological Survey offers information on many aspects of water, along with pictures, data, maps, and an interactive center where you can give opinions and test your water knowledge.
