Laboratory Activity 1: Water Bending Objective: This activity will help you acquire real-life concepts of static electricity. Materials: 0 3 Styrofoam! paper cups 0 Scotch tape 0 l toothpick 0 Comb, ballpen, pipe, balloon or any object available in your house. 0 Water 0 Basin 0 Improvised ring stand! ask someone to hold the cup during the experiment. Procedure and Questions: 1. Prepare the set-up by pushing the toothpick at the bottom side of the cups. Leave the toothpick to produce a gentle drop of water after lling the cup. Hold the cup directly over the second cup. Fill the cup (with a toothpick) with water and check if it is leaking steadily. 2. Observe the ow of water from the top cup to the cup below. What are your observations? Answer: 3. Rub the third cup on someone with dry hair several times. (This process will help you in acquing electrical charges). 4. Hold the cup (rubbed against dry hair) near the water stream without getting the cup wet. What happened to the water ow? Answer: 5. Then, slowly move the cup away from the stream and observe. Did you observe changes? If yes, describe the change. Answer: 6. Try other objects (such as balloon, paper cup or any material) aside from the Styrofoam cup and rub it on a dry and clear hair. What objects have you tried? Answer: 7'. Which of the objects have changed the flow of water? Answer: CONCLUSION
