2. Daily Reflection
Prompt: What allows birds and airplanes to fly?

3. Archimedes BC
King Hieron suspected that the gold crown that he received from his gold smith was not of pure gold
He asked Archimedes to investigate and prove his findings

4. How did Archimedes solved the problem?
He knew Gold and Silver weighed different amounts
If he knew the volume of the crown then he can compare it’s weight against the weight of equal amount of gold and silver
How can you find a volume of crown?

5. How did Archimedes solved the problem?
While taking a bath, he realized that the water that ran over equaled in volume the submerged part of his body
He now knew the volume of the crown and by weighing it he proved that it was not made of pure gold.

6. Archimedes’ Principle

7. Pascal’s Principle
When force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid

8. Hydraulic Device

9. Hydraulic Brakes

10. Bernoulli's Principle
faster a fluid moves, the less pressure the fluid exerts.

11. Does the Movement of Air Affect Pressure?

12. Bernoulli's Principle :Why do airplanes fly?

13. Bernoulli's Principle : Why an atomizer works

14. Bernoulli's Principle: Why hot air rises
