Dennis makes an electromagnet. He is kind of surprised when it actually works and he's able to pick up metal objects with it. Even still, he's not satisfied with his electromagnet because it's very weak. What can he do to make it stronger? Select the best answer.

• use a plastic nail

• wrap the wire around the nail more times

• glue the wire to the nail

• use a different brand of battery

• wrap the wire around the nail less times

Draw and label a PARALLEL circuit.

Sidney wants to make an electrical circuit. She gathers a light bulb, wire, and a metal screw. To make a complete circuit, Sidney need to add a ​ (a)   .

• power source

• switch

• insulator

• conductor

• load

A student is investigating whether the magnetic field is affected by different materials.

Move the statement to the blank space to show the CORRECT order of steps for the investigation.

Step 1: Place 10 iron thumbtacks close together on a table.

Step 2: ​ ​ (a)  

Step 3: Tie a string around the magnet

Step 4: ​ (b)  

Step 5: ​ (c)  

Step 6: Repeat steps 1-5 with different materials, such as a cotton ball, notebook paper, and aluminum foil

• wrap tape around the magnet to hold the magnet

• slowly lower the magnet towards the thumbtacks

• count & record the number of thumbtacks picked up

Will the light bulb in this circuit light and why/why not?

• yes, because it has two batteries

• no, because the switch is open

• yes, because it is in a circuit

• no, because the bulb is burned out

What type of circuit is represented by the diagram?

• closed

• series

• open

• parallel
