Essential Questions 4.3

Anticipatory Set

Thousands of years ago the human race began its long relationship with fluid systems. We first recognized the ability of transferring power with the use of fluids quite early. Blowing on embers to start fires, allowing the current in a stream to wash debris, floating logs down stream were easy things to understand. We then started making devices that would use the power of fluids. Some of the first instances were bellows, water wheels, sailing ships, wind mills, dams, and sluice gates.



While air and water might not appear to be the same at first, they behave in many of the same ways and the devices we use with them are very similar.
