This week students continued to work on finding the PERIMETER of polygons and also practiced to find the AREA OF A RECTANGLE (concept seen in gr.5) but this time we added the FORMULA:
A = L x l
We also studied the concept of VOLUME. With many examples, students understood the meaning of it and learned to use the FORMULA (why? and how?) for rectangular prisms:
V = L x l x h (longueur x largeur x hauteur)
Science:
This week we continued to study 'air' and its characteristics.
A few demo (+ notes) were done in class to demonstrate characteristic #4 :
Air is compressible
and characteristic #5:
Temperature impacts air
We had our last presentations on 'Actualité scientifique'
