Wonderful Wednesday!

Our song for the Christmas concert:

We began the day with Music and then dove into math. 

Students learned about using variables in measurement formulas to find the area and perimeter of a square and rectangle. Students were reminded of the word formulas for the perimeter and area of a squares and rectangles that they learned last year:

What does the area mean? (the number of congruent square units that fit in a figure)

What does perimeter mean? (The distance around a figure in units)

Students recalled that the area of a rectangle is base times height. Students needed to understand that the base of a rectangle is the side perpendicular to the height and, when we say “base times height,” we mean the length of the base multiplied by the length of the height.

Perimeter measurements are in units.

Area measurements in square units.

We reviewed some examples as a class. Students understood the term variables, perimeter of a square, and that perimeter can also be written P=2b + 2h = 

perimeter is double the plus double the height 

Both formulas give the same answer 

P=2b + 2h = we double the base and height, then double the sum 

Today’s Success Criteria:

I understand that the perimeter and area of a rectangle and a square can be expressed using formulas

I know that the perimeter of a rectangle is P= 2 (b+h) or P = 2b + 2h

I know that the perimeter of a square is 4s

I know the area of a rectangle is A=bh

I know that variables in a formulas can represent different numbers 

I know that perimeter is written in unit and area is written in units squared 

Then we dove into UOI. Today we learned why hot air ballon fly. First we watched a video to see how we can make our own hot air balloon and then we watched a video which explained why hot air ballons fly.

Hot air balloons fly when the air inside the hot air balloon is less dense than the air surrounding it. Hot air is less dense than cool air; the heated air causes the balloon to rise simply because it is lighter than the cold air around it. This is called Buoyancy. 

After first recess and lunch, we had French. 

Then we began our inquiry into flight!!! We did various experiments today to explore how high pressure air (low speed) and low pressure (high speed) air are used create lift! We will apply todays learning to understand why planes fly. We were challenged to research about Bernoulli’s principle and to problem solve how our experiments relate to Bernoulli’s principle. 

After second recess and lunch we continued working on our book report for the City of Ember.

Homework:

1. Read Daily
2. Finish answering questions about hot air balloons and experiments
3. Math pg. 96 1-6
