Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the governing principles?Hydrostatic pressure, atmospheric pressure, and gravitational potential energy
2. What is the related scientific concepts?Bernoulli's principle, Pascal's principle, fluid dynamics, and cavitation
3. What is a siphon and how does it move water uphill?A siphon is a bent tube that uses pressure differences to move liquid from a higher to a lower level, letting water flow over a hump and down the other side.
4. Why does the liquid in a siphon need to fill the whole tube first?The tube must be full so there is a continuous column of liquid, which lets pressure differences push the water up and over the bend.

Hydrostatic Pressure: The pressure exerted by a fluid at equilibrium due to the force of gravity.
