Purpose Hypothesis Procedure Observations and Results ConclusionPowerPoint Presentation: 1 . Purpose The purpose of this activity is to find out if electricity can be made from some fruits . 2. Hypothesis Fruits can generate electricity 3. Procedure A. ResearchPowerPoint Presentation: Electricity Is one type of energy or power. The electricity in one form or another is all around us. For example, our bodies and other living things have electricity in them. By controlling the electricity around us, by making it work for us, we have changed the world. Pioneers in Electricity In 1752 Benjamin Franklin used a kite to prove that lighting was electricity. Thomas Edison invented the first successful electric light bulb and the first electrical power distribution company.PowerPoint Presentation: Making Electricity Using Electricity We use the energy of electricity in our homes, schools, businesses, hospitals, etc. Electricity has helped bring the countries of the world closer by speeding up and improving communication. Our telephones, televisions, and other communications instruments all run on electricity. People make electricity at electric power stations. Machines called generator make electricity from other forms of energy such as coal, falling water, wind, gas, oil or atomic energy. Wires or conductor are the ones that carry or conduct the electrical current.PowerPoint Presentation: B. Experiment Materials: 3 copper wires 3 copper strips 3 zinc strips 3 limes 3 oranges 3 apples Multi tester or battery tester.PowerPoint Presentation: Procedure Get the 3 limes on flat surface, on each lime stick a copper strip and a zinc strip on opposite sides. Connect a copper wire to the copper strip of the first lime to the zinc strip of the second lime; then, connect a second copper wire to the copper strip of the second lime to the zinc strip of the third lime. Connect another wire to the copper strip of the third lime to the red lead of the tester of the third lime, and connect a wire to the zinc strip of the first lime to the black lead of the tester. Watch the needle move in the tester battery tester. Repeat the same procedure with apples, bananas, and one of each fruitPowerPoint Presentation: 4. Observations and Results 1. What happen when we connect the limes to the battery tester? The needle on the battery tester jumped, that shows limes can generate a small amount of electricity. 2. What happen when we connect the apples to the battery tester? The needle on the battery tester jumped, that shows apples can generate a small amount of electricity. 3. What happen when we connect the bananas to the battery tester? The needle on the battery tester jumped, that shows bananas can generate a small amount of electricity. 4. What happen when we connect a banana, a lime and an apple to the battery tester? The needle on the battery tester jumped, that shows bananas can generate a small amount of electricity.PowerPoint Presentation: Volts measured from fruits & vegetables Electrodes Zinc/Steel Copper/Steel Zinc/Copper Fruits & Vegetables Apple 0.27 0.39 0.82 Orange 0.29 0.34 0.76 Carrot 0.29 0.31 0.75 Banana 0.26 0.37 0.73 Lime 0.30 0.25 0.71 Tomato 0.30 0.29 0.70 Lemon 0.30 0.33 0.70 Potato 0.23 0.31 0.64 Cucumber 0.26 0.29 0.60PowerPoint Presentation: 5. Conclusion We can generate only a small amount of electricity from fruits. In this experiment I used apples, bananas, and limes to produce electricity.
