(NEED HELP PLS) Hypothesis
Record your hypothesis as an "if, then statement. (If the independent variable does this, then the
dependent variable will do that...)

Variables
List the independent (test variable), dependent (outcome variable), and controlled variables. Be sure
to change just one variable for each trial.
Procedure

1 Use the virtual laboratory to create an electromagnet, changing only your independent
variable
2 Record the data and what each variable was set at for each trial.
3. Record the number of paper clips the electromagnet picked up for each trial (this is the dependent variable and reflects the strength of the electromagnet).
4. repeat your trail three times. You should vary only the independent variable you choose.

Data
Record your data for each trial. Be sure to change just one variable at a time. This will allow you to see which variable affect the number of paper clips collected.

trail 1:
size of wires gauge:
material of wire:
voltage:
number of winds:
resulting paper clips picked up:

trail 2:
size of wires gauge:
material of wire:
voltage:
number of winds:
resulting paper clips picked up:

trail 3:
size of wires gauge:
material of wire:
voltage:
number of winds:
resulting paper clips picked up:

post lab questions:
1. review your data. did your experiment support your hypothesis? explain your answer.
2. what role does voltage play in the formation or use of an electromagnet?
3. if you were able to keep the electromagnet that you created in your laboratory activity, what would be two possible uses for the electromagnet?
4. what is an advantage of using electromagnet rather than a regular magnet?
