Tremendous Thursday!
Ronit won our SJA costume contest!!!
We began the day with math. Our learning goal today was to find the surface area of a rectangular prism using the formula SA = 2lh + 2 lw + 2 hw. We were introduced to the surface area of a rectangular prism. Students came to understand that there must be three variables for any measurement formula for a prism; we use l, w, and h since b for base refers to the rectangular base of the prism. We learned we are finding the area of each rectangle and then adding them together to get the answer and when the sides are congruent you can multiply by 2.
Broken down steps: https://www.wikihow.com/Find-the-Surface-Area-of-a-Rectangular-Prism
The surface area of the prism is the sum of the areas of the rectangles.
The surface rea of the prism = 2lh + 2 lw + 2 hw
We write = SA = 2lh + 2 lw + 2 hw
OR SA= 2(lh + lw + hw)
-measured in units squared
Surface area of a cube:
We find the area of one face and then multiply by six since a square has six congruent faces.
When given the total amount you just need to divide by 6 since all the faces have the same area.
Today’s Success criteria:
I understand that:
- the surface area of the prism is the sum of the areas of the rectangles
The surface rea of the prism = 2lh + 2 lw + 2 hw
We write = SA = 2lh + 2 lw + 2 hw
Another way:
SA= 2(lh + lw + hw)
- for the surface area of a cube, when given the total amount you just need to divide by 6 and to get the length, divide that number by 3
Then we dove into UOI. We reviewed our research about Bernoulli’s principle.
Here is a video that helps to explain how the activity that we did with the ping pong ball and funnel and why the ping pong ball stayed in the funnel instead of coming out and how it relates to why planes fly:
More of an explanation on Bernoulli’s principle.

Notice that the air flow is going the opposite direction of the plane.
During class we reviewed Bernoulli’s principle and how it related to the experiments we did yesterday.
After first recess and lunch we had French.
Then we continued working on our book reports. We will finish these up tomorrow.
Next we had a Halloween party where we did a dramatic reading of our 'Before Midnight Poem', listened to Halloween music, danced, played and chit chatted with friends.
At the end of the day we had physical education with Mr. Orr.
