Prisms and Historical Artifacts on Thursday

Here are some photos of our continued journey into geometry and Alberta's Mavericks:

Prisms, angles and optical illusions.  

Recording our findings about  the effects of light through glass prisms.  How do angles  can change perspective.   
 Here's a little video showing how this convex glass prism shows refraction: 


Concave means lens curve inward like a bowl.  Convex means curves outward.  

 light travels in a straight line and refracts when it passes from one substance to another, is the principle behind why a prism separates white light into individual colors.

Testing out Reflection.  

Using nets to make triangular prisms.  What shape would you get if you took a cross section of this prism?



Today we used a historical artifact to explore important Mavericks from Calgary's Past.  These books from 1989, really sparked some amazing conversation.  We did a See, Think, Wonder thinking routine to explore the stories and impacts of these important people.
