Conservation of energy and resources

  1. 1. Energy Experiment: Waterwheel Yunice Chee G5L Feb 2012
  2. 2. Why waterwheel can be an energy?P. 2
  3. 3. 1. 2.3 liter plastic bottle 2. Ruler 3. Scissors 4. Marker 5. Craft knife 6. 1 awl 7. 1 cutting board 8. 2 corks 9. 1 wooden barbecue stick 10. 1 fishing threadP. 3 11. Fishing sinker weight about 1 oz
  4. 4. 1. Cut the bottom of the bottle 2. then cut 8 pieces of blades with into 8cm deep. 4cm long x 2cm wide.4 Yunice Chee G5L
  5. 5. 4. Cut slits with a craft knife and push a blade into each slit, make3. Draw eight lines evenly on sure the strips all curve in the one side of a cork. same direction.5 Yunice Chee G5L
  6. 6. 6. Cut a BBQ stick into 2 half and put 15. Cut away middle the section of 1 side of half through to a hole and the end the bottom, use an awl to make two hole goes to a side of cork, and the other below the rim and big enough for a BBQ side is the same, to hold the wheel in stick to go through & move easily. the middle. 6 Yunice Chee G5L
  7. 7. 7. Use the awl to make a mark in the 8. On one side, tie a fishing thread middle of the second cork, then put with the cork and on the other the cork in either side of a stick. side with fishing sinker. 7 Yunice Chee G5L
  8. 8. 9. Put the wheel under a tap, open the tap, the wheel will rotate by falling water striking blades near top of the wheel and lift the weight.8 Yunice Chee G5L
  9. 9. Water will turn the water wheelto move, so water is a renewableresources.P. 9
  10. 10. Water can replace the electricity to provide the energy to power a heater and so on.P. 10
  11. 11. 1. We will always need energy. Power plant burn the coal and oil to make electricity which provides the energy to power a heater but they are not renewable resources. However, water is renewable resource can replace over time. 2. This experiment is useful because using water wheel can reduce the amount of fossil fuels needed in electricity. It is a renewable resource and will not be used up. It also does not product air pollution. Air pollution might affect our health and cause lung cancer.P. 11
