## CTE Task: Bernoulli's Principle

 COURSE: Engineering Design II TASK LENGTH: 1hr

## Fluid Power Systems

Standards

In this task, students will develop or recreate an experiment to demonstrate Bernoulli’s principle.

Standard 11: Using various sources such as the internet and textbooks, research various applications of Bernoulli’s principle and identify specific examples to demonstrate the principle. Develop and lead a lab activity to teach Bernoulli’s principle to the class.

Content Understandings

Extending Understandings

Upon successful completion of these tasks students will demonstrate the ability to:

1. Demonstrate and explain Bernoulli’s Principle.

To move students towards deeper understanding, they should be given opportunities to:

• Explain what variables impact Bernoulli’s Principle.

Support Strategies

If students are struggling to access this task, additional supports and strategies could be employed as students are engaging with the task.

 Key Terms Sentence Frames Scaffolded Questions Bernoulli’s Principle   Pressure   Fluid _____ is the mathematical representation of the Venturi effect.   As_____ velocity increases the _____decreases. How does Bernoulli’s principle relate to the conservation of energy?   Why is pressure important to Bernoulli’s principle?   What happens when fluid is forced to move faster in Bernoulli’s principle/equation?

This activity will require students to apply what they learned during the lesson/lecture on Bernoulli’s Principle to a hands-on activity.

1. The teacher will divide the class into groups of 3 or 4 (depending on size)
2. The teacher will give each team a list of 3 reparable websites to review Bernoulli’s Principle.

Here is an example of 3: (you may use these or find your own)

• Pbslearningmedia.org
1. Each team will use a predetermined platform e.g, Microsoft teams, zoom etc. to develop a lab activity to showcase Bernoulli’s Principle given materials found at home.
• Example materials, could include but not limited to:
1. Soda cans
2. Balloons
3. Paper plates
4.  Balls
5. Cups
6. Straws
7. Blow dryer
8. Fan
9. Toilet paper
10. Tape
11. Glue

1. Once completed each team will share back with the class using, words, drawings or a live example on why their experiment demonstrates Bernoulli’s principle. (on the predetermined platform)
