Electricity Unit - Lesson 1 Static Electricity

Static Electricity ExperimentWhat you'll need:balloons, wool fabric, wax paper, a volunteer's head, mixed salt and pepper, confetti, sheet of paper1. In your group, pour some salt and pepper onto a sheet of paper. Bring an uncharged balloon (normal balloon) close to the salt and pepper mix. Answer Observation Question #12. Now, charge the balloon by rubbing it against the wax paper and move the balloon close to the salt and pepper mix again. Answer Observation Question #23. Repeat step 2 two more times using the wool fabric and a volunteers hair. Answer observation Questions #3 and #4. 4. Wipe the balloon down with a damp cloth. What does this do to the balloon and its charge? Answer Observation Question #5Complete your Final Observation Question for this experiment: Did the salt and pepper react in the same way? Explain why or why not.1. In your groups, pour some confetti (or bits of paper) onto a sheet of paper. Rub the balloon with wax paper, wool fabric, and hair one at a time and record what happens when you bring the balloon near the confetti. Answer Observation Question #6-#8Complete your Final Observation Question for this experiment: Why were the pieces of tissue attrached to the baloon? What else might be attrached to a charged balloon?

What is Static Electricity and how can we create it?

Movie Response

After watching the Bill Nye video on Static Electricity, answer the movie response questions in your Science Journal. Then start your experiment!

Watch the Video

1) Draw a sketch of the "Van Der Graf generator" and show the path of the electrons in the machine2) Why did Bill Nye's wig stand up when he touched the Van Der Graf generator?3) Why did his hair go done when he touched the small metal ball to the Van Der Graf generator?4) Fill in the blanka) Like charges_______________ one anotherb) When electric charges jump to ground you see _______________________c) Embarrassing static build up on clothes is called ______________________d) How do you get rid of static cling _____________________________5) List 3 fun things you can do with static electricity!

1. Read about Static Electricity 2. Watch the Bill Nye video on Static Electricity3. Answer the movie response questions in your Science Journal4. Start your experiment and watch what happens!

If you want to know what static electricity is we need to learn about a little guy that is in everything. It's called an atom. An atom is made up of three parts; a neutron, a proton (which together make the nucleus (middle) of the atom), and an electron.An electron is and moves around the outside of the nucleus. A proton is and happily sits along side the neutons inside the nucleus.A neutron is neutral, which means it doesn't have a charge (it's not + or -)Electrons can be easily transferred from one atom to another because they are loosely held around the outside regions of the atom. When there are enough electrons (negative charge) on an object it starts to act like a magnet and either attract the opposite charge or repel the same charge
