Write what each word means, using the article.

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 fundamental principle?Creation of a pressure differential to induce fluid flow
2. What is the historical significance?Crucial for mine dewatering during the Industrial Revolution, enabled by steam engines
3. What is a pump and how does it move liquids?A pump is a machine that gives energy to a liquid or gas, making it move. It can use electricity, gears, or a spinning impeller to create a pressure difference that pushes the fluid.
4. How do pumps work in everyday life?Pumps help bring clean water to homes, move oil in cars, and even help doctors give medicine. They use different types like centrifugal or piston pumps to fit the job.

Centrifugal Pump: A rotary pump that uses an impeller to increase fluid velocity and pressure.
Positive Displacement Pump: A pump that moves a fixed volume of fluid per cycle, regardless of discharge pressure.
Multi-Stage Pump: A pump with multiple pumping elements arranged in series to achieve higher pressures.
Biomimicry: The design and production of materials, structures, and systems that are modeled on biological entities and processes.
