Week May 24-27

Math

This week we started chap.8 - 'Les transformations'. We covered 'translations', 'réflexions' and 'rotations' (90, 180, 270 degrees ) with lots of exercises in class. Students should be able to perform those 3 transformations also identifying coordinates (positive only). 

Translation 

Réflexion 

Rotation 

Science

This week we studied the 4 forces involved in the aerodynamic of flight:

LIFT (portance)  /  WEIGHT (poids) / PUSH (poussée) / DRAG (traînée) 

Students also explored and took notes from the website called `The Thrill of Flight`

Week May 16-19

Math

On Monday, students had a practice test in class (questions on the board) and time to review chapter 6 - triangles, polygons, perimeter, area, volume (exercises in the textbook p.240)

On Wednesday, they wrote their TEST on chapter 6 - geometry. 

Science

This week we studied Bernouilli`s principle in detail with many demonstrations in class + drawings + diagrams + explanations + videos.

The main idea is :    fast moving air -->  LOW pressure 

Bernouilli`s principle explains the LIFT created on a airplane (low pressure on top of the curved wings)

Week May 9-13

Math:

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'

Week May 2-6

Math:

This week students learned about POLYGONS and how they are classified:
'polygone régulier' - 'polygone concave' - 'polygone convexe' - 'polygones congruents'.

On Friday, we worked on finding the PERIMETER of polygons (concept seen in gr.5) but this time we added a few FORMULAS: 

Square:
P = 4c  (c: côté)




Rectangle:
P = 2L + 2l  (L: longueur    l: largeur)

Science:

This week we continued to study 'air' and its characteristics.

A few demo were done in class to demonstrate characteristic #3 :

Air has pressure

We also continued our presentations of 'Actualité scientifique'.
