How do you see a Rainbow?

 

 

The following resources were collected to support a Backwards and UDL-Designed science unit created collaboratively by grade 8 teachers at PRMS.  On the first day of the unit, the students made a hypothesis about how you see a rainbow. Over the term, they refined their hypotheses as they learned more about optics.  The resources are grouped by the Essential Questions students explored.

General Resources 

BC Science IRP

The Optics Unit outcomes are available in .pdf form (see pages 46, 72, 72-81).  The PLOs are:

C1  demonstrate knowledge of behaviour of waves

C2 explain properties of visible light

C3 compare visible light to other types of electromagnetic radiation

C4 explain how human vision works

 

BC Science 8 Website Links and Online Optics Chapter

Check out the BC Science 8 Learning Centre for the Optics chapter.  Here you can find links to websites on many different topics related to light organized to correspond with page numbers in the text.  No password is required to access this section.

At BC Science 8 Home Version, you can also read the Optics Chapter online, download it as a .pdf, or download excellent study guide questions.  (You need a password to sign in to read the chapter online.)  BC Science 8 is also available in .pdf and Kurzweil format at ARC-BC.

 

World Book Online

World Book for Kids and  World Book for Students have many articles on topics related to light.  Double-click on words to see their definitions.  Both websites will also read the articles to you.  You can also print or download the articles.  To bring a World Book Online article into Kurzweil, print the article to the KESI Virtual Printer.
