Friday November 2, 2018

Fabulous Friday!!

We began the day with Math. We reviewed conversion rules between cm-metres-kilometres; millilitres-liltres; grams-kilograms.  
The skills we need for our upcoming unit on rates and ratios is being able to find the GCF and LCF and conversion rules. 

Next we worked on our OWA writing a fable or a legend about how an animal came to be or how it got one of its unique features. 

Then we worked on our electric cars. We are testing our car to see how far it is able to go and then trouble shooting any problems we come across.

After first recess and lunch we reviewed Bernoulli’s principle: an increase in the speed of moving air or a flowing fluid is accompanied by a decrease in the air or fluid's pressure.

We went over our notes on Bernoulli’s and drew a diagram to explain Bernoulli’s principle. 


What is the shape of an airfoil?

An airfoil aerofoil is the cross-sectional shape of a wing, An airfoil-shaped body moved through a fluid produces an aerodynamic force.




What is the direction of the plane and the airfoil?

The plane and the airfoil are both moving forward together. The plane and the airfoil move in the same directions 

What is the distance air travels over and under the airfoil?

The air that goes over the airfoil is travelling over a greater surface area and therefore has a greater distance to travel. The surface area is lesser at the bottom of the airfoil and therefore has a lesser distance to travel. 

What is the direction of airflow over the airfoil?

The direction of airflow is backwards relative to the plane.

What is the speed above and below the airfoil?

The speed above the airfoil is quicker than the air below the airfoil. 

What is the air pressure above and below the airfoil?

The air pressure is lower at the top of the airfoil and higher at the bottom of the airfoil. 

What is the direction of lift?

Since particles flow from high pressure to low pressure the direction of the lift is going up.

Students completed a carousel activity where students took turns explaining Bernoulli’s principle and drawing a diagram that related to their explanation. Kids teaching other kids really helps students understand the concept learned!!!!















Have a wonderful weekend!

Homework:

1. Read Daily
2. Math sheet
3. Complete sheet - making notes on Bernoulli's Principle related to flight
4. Bernoulli test on Monday
