Introduction to Electricity Stations Lab
1. Build a simple circuit with a light bulb in a socket.
a. How do you know that the circuit is working?
b. Remove the light bulb from the socket and make it light. Make a
circuit sketch below:
2. Electroscope
a. Rub amber against the nylon to produce free charges. Place the
amber close to the electroscope without touching it. What do you
observe? Why does this happen?
b. Draw a sketch of the charges on the gold foil leaves.
3. Pith Balls
a. Rub amber against the nylon or fur to produce free charges. Place the amber close to the pith ball without touching it. What do you observe? Why do you think this happens?
b. Draw a sketch of the charges on the pith ball and on the amber.
4. Conductors and Insulators
a. List the items in the chart below.
b. Use the materials at your station to determine if the item is conductive or insulating.
Item / Conductive or Insulating?5. Electromagnet
a. Before connecting the circuit, are the nail or paper clips magnetic?
b. Connect the coils around the nail to the circuit. Touch the nail to
the paper clips. What do you observe?
c. Are the nail or paper clips part of the circuit?
