How do I build a small water pump for a Science Fair experiment?

Question

My goal is to demonstrate how water flows uphill by creating a small water pump and pumping water through small tubes. I need something NOT LARGE OR BULKY and inexpensive. I would like to build it myself...links, designs, and guides are good.

Go to a pet store and buy an aquarium pump.

Your question would be replied in some steps the 1st step is you may create electrical energy- to try this you will choose a small generator/alternator to create AC power. The generator/alternator has 2 significant areas- the 1st being coils of twine and the 2d being magnets related to an enter shaft which spin whilst the enter shaft spins(which might then hook up with a waterwheel). The coils of twine are arranged exterior of the circumference of the place the magnets spin. The magnets each and each have their very own magnetic container and since the magnetic container "passes by" the coils an electric powered impulse is made.those electric powered impulses are pronounced as AC power(alternating present day). gazing the dimensions of the water wheel you may could use a transformer to "step down" the ability if it advance into too extreme. the subsequent step would be to apply an AC to DC (direct present day) converter so as that the electrical energy may well be utilized by your motor. An AC to DC converter makes use of diodes and arranges them to create a + and - can charge. After the AC to DC converter, you may purely connect the unfavourable and useful terminals to the corresponding ones on the motor. in case you have any questions, please be at liberty to study throughout the hyperlinks below or seek youtube for video clips on how electric powered turbines, transformers and automobiles artwork.

I once built one with a windshield washer pump from an auto parts store and some batteries. Worked fine. It was the Colorado River, for a sixth grade project.
