Question

how to make a electrosocope and state how it is working?

Answer 1

material
clear glass jar*
.Jar lid or piece of plastic large enough to cover the opening of the jar
*.Electrical tape
*.Copper wire, 14g or thicker*.Straw
*.Scissors
*.Glue gun
*.Aluminum foil or gold leaf*.Vinyl record
*.Rubber soled shoe
*.Carpet
*.Balloon
*.Any other material you want to test!

rocedure1.Perform this experiment on a dry day! The experiment might not work if it is humid orraining.Why do you think this is important?
2.Use the scissors to cut a two-inch long piece of straw.
3.Have an adult punch a hole through the center of the jar lid or piece of plastic big enough to fit the straw through.
4.Insert the straw into the hole for your lid. Hot glue the straw so it is securely fastened to the lid.
5.Cut a 10-inch piece of copper wire.
6.Twist the top 4 inches into a circle or spiral to create some surface area.If we’retrying to test the presence of an electric charge, why do you think having a larger surface area better? Why is thicker wire better?
7.Insert the straight end of the wire through the straw and create a hook about 1 inch long.8.Hang two small pieces of foil or gold leaf on the hook. Make sure they are in contact.Why do you think we’re using two pieces of metal as opposed to one? What do you think the two pieces of metal are there to do?
9.Place the hooked end of the metal into the jar and twist on or tape the lid to the jar.
10.Now it’s time to give our materials a static charge! Rub each of your materialsvigorously with your hand or a piece of wool.Can you explain how this helps giveeach object an electric charge?
11.After you give each of your objects a charge, bring each object near the coiled wire on your electroscope. Be sure to record your observations


!Extra:*.Try rubbing the balloon on your hair.*.Try rubbing your shoes on the carpet and then bring the electroscope close to the sole of your shoe.*.Rub the vinyl with your hands.
