There will be a quiz on Chapter 7 and part of 8 mid next week.  Watch this space for details.  The worksheets and slideshows are now available online.

Last class, we took a look at the Bill Nye video on Fluids (the worksheet we used can be found in with the Unit 3 documents).

Next class, we are going to have a look at non-Newtonian fluids - cornstarch and water to be exact.  Non-Newtonian just means that when Newton described fluids back in the day, he talked about them having predictable viscosity that was affected by temperature... non-Newtonian fluids don't follow The rules that Newton came up with.  The viscosity of cornstarch and water is affected by pressure, not temperature.  Here are a few videos to demonstrate.

There will be a test on Unit 4 (Ch. 10, 11, 12) on Wednesday, May 21.  All review sheets can be found in the Notes and Worksheets section of this web page.  There will be a Science Help session after school on Tuesday (May 20) for those students who would like to review for the test on Wednesday.

Review sheets for Chapter 11.  Body Systems Review, Chapter 11 Review and Chapter 11 Review Quiz.
