Fabulous Friday!

Can you believe it is already November!! How time flies!!

For our upcoming Christmas concert, our class will be doing a scene from Charlie' Brown's Christmas. If students are able to find the movie online, they are encouraged to watch it. We will be doing a scene and singing a song. The link below will be the song that we will all sing as a class. Students are asked to start practicing.

We began the day with Music.

Then 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. Students participated in a carousel activity where they had an opportunity to explain Bernoulli’s principle and get peer feedback as well as listen to a peer explain Bernoulli’s principle and provide feedback for them. 

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 direction.

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. 

In other words, lift is created by the flow of air over the airfoil. The wing generates lift because air goes faster over the top of the airfoil creating low pressure, causing the wing to lift toward lower pressure since higher pressure wants to move towards lower pressure. 

After first recess and lunch we had French.

Then we finished writing our book reports for The City of Ember.

We spent the rest of the days working on building, testing and troubleshooting our electric cars.

Have a great weekend!
