Laboratory Activity 3: Let's Do Physics! Objective: you will be performing simple experiments that will help you have a clearer understanding about the two charging processes - rubbing and induction. Materials: 0 Comb 0 Tiny bits of paper 0 Water source (faucet) 0 Drawing materials Procedures: 1) Charge the comb by running it through your hair. This works well when the weather is dry. 2) Place the comb near the tiny bits of paper. Observe what happens. 3) Repeat step 1. 4) This time place the charged comb near a thin stream of running water from a faucet. Observe what happens. Answer the following. Write your answer in a separate sheet of paper. 1) Draw and describe what you have observed when the charged comb was placed near the tiny bits of paper. 2) Draw and describe what you have observed when the charged comb was placed near a thin stream of running water from a faucet. 3) What type of charging process took place between: a. the comb and your hair? b. the charged comb and the tiny bits of paper? c. the charged comb and a thin stream of running water from a faucet? 4) What is the role of electron transfer in the charging process that took place between the comb and your hair? 5) Explain the following charging processes: (a) rubbing and (b) induction.
