Question

Describe the procedure to make the sample of the following:
A simple electroscope​

Answer 1

Answer: Electroscope Parts

Petri dish lid

Beaker (250 mL) or comparable glass container

Copper Wire, large gauge

Aluminum foil

Adhesive, quick dry (e.g. hot glue)

Clinometers (downloadable link)

Tools

Drill with drill bit

Wood/Metal (to place dish on while boring hole)

Needle nose pliers

Scotch Tape

Scissors

Hole punch or pencil

Testing Materials

PVC tube

Glass rod/stirrer

Wood dowel

Wool cloth

Cotton cloth

Polyester cloth

Procedure

Ensure that your petri dish, either the top or bottom, fits around the top of your beaker.

Place the petri dish flat side down on a sacrificial piece of wood or metal and use either a drill press or hand drill to bore a hole in the center. Use a drill bit which is slightly wider than the diameter of your copper wire.

Cut a 15-20 cm length of wire and, using needle nose pliers, bend the top half into a spiral perpendicular to the rest of the wire.

Insert the straight end of the wire into the hole in the petri dish. Use the needle nose pliers to bend the end of the straight half of the wire into a hook.

Use fast acting adhesive such as hot glue to fix the wire in place on the petri dish with the spiral 1-2 cm away from the flat side. It might be easier to rest the flat side of the dish on the copper wire roll or roll of tape with the spiral positioned downward to hold the setup in place while the glue dries.

Once the glue is dry, place the petri dish and wire combo over a beaker or glass jar and secure the wire with glue on the side with the spiral.

Fold a flattened piece of aluminum foil in half. Using a hole punch or pencil, create a hole slightly wider than the diameter of your wire, with the edge of the hole 1-2 mm away from the folded end of the rectangle. Cut the aluminum foil into a 1 cm by 2 cm rectangle with the hole centered. Separate the two pierced rectangles of foil by cutting along the fold.

Cut out the clinometers with scissors. (also linked in the Materials section)

Bend the top end of the angle gauge to create a flat area where you can tape the angle gauge to the petri dish. The dot in the center of the angle gauge should be directly behind the apex of the hook. Ensure that the paper is parallel to the hook and separated by a 1-3 cm gap.

Hang the two aluminum foil leaves on the copper wire hook.

Place the entire assembly on the beaker and proceed to the activity.

Answer 2

Answer:

An electroscope is an instrument to identify the presence of an electric charge on an object.

Explanation:

• From a straw, cut a 2-inch piece
• Make a hole through a plastic lid which is the size of the straw
• Put the straw through the hole in the lid
• Use glue or tape to secure the straw
• Take a copper wire which is 10 inches long
• Make a spiral out of the first 4 inches of the copper wire by twisting it
• Insert the straight part of the copper wire through the store and make a hook out of 1 inch of the wire
• Take two pieces of gold leaves and hang them from the hook
• The gold leaves should be in contact with each other
• Now put the hooked end of the wire into the jar
• Screw the lid onto the jar and secure it

Using the above steps, we can make a simple electroscope.
