Common Eye Defects

Today we watched a video on common defects of the eye and filled in some notes based on it.  Know where light converges on your retina if you are far-sighted and near-sighted and how lenses can fix the problem.  A second video showed how our brain adjusts the upside down image on our retina for us.  At the end of class we went over some of the multiple choice questions on the optics review.

The Eye and its structures

Today we prepared for the cow eye dissection by watching two videos.  One on how an eye works and the other on the steps in the dissection.   We then coloured and labelled all the parts of the eye.  Use page 204 if you need to review these.    The actual dissection happens on Thursday!  

Mirrors

Today we had a quick review of reflection and refraction of light.  We then took some short notes on mirrors and the three types of mirrors:  plane, convex and concave.   We then did a worksheet:  Using mirrors to form images and looked at our reflection in the concave/convex mirrors.  The worksheet is due on Monday. 

New marks are posted here  Get in your missing work before the optics test on Friday!!

Reflection and Refraction of Light

I collected the field trip permission forms and marks progress reports. 
Students took notes on how light can be reflected, transmitted or absorbed.   They learned the difference between reflection and refraction and how the angle of light change in each case.   Students then completed the Activity 5-2 on page 176.  Homework: pg. 164 #1-15  (don't do #4 or #14)

Review of Waves and Light

Today we started with a review of Waves, Visible Light and the Electromagnetic Spectrum (Ch. 4).   We did another demo on UV light to show why you need to wear sunscreen!
We completed the Electromagnetic Spectrum handout in class or for homework.  

Each student was sent home with the field trip permission form due tomorrow and a mark summary. Only two weeks left!  Keep working until summer officially starts :)

Know Your Watershed Field Trip Wrap Up

Today we wrapped up the Know Your Watershed Field Trip #1 with Ms. Vickers.  She will be back next week-on Thursday June 9 so that we can paint storm drains during the double block.   Make sure the second (green) permission form comes back so that you can go on this trip. 

Know your Watershed Week

This week we have a special presentation by Wildsight's Ms. Vickers.  She will be presenting the "Know Your Watershed" program.  Make sure you bring in your permission forms by Tuesday May 31 in order to go on the Wednesday field trip.  This whole week is dedicated to this program.
