S5P2 and S5P3 CSA Retake

When you move the switch of a flashlight to "on," the light goes on. When you move the switch of a flashlight to "off," the light goes off. How does this happen? ​ ​

• The switch in the "on" position closes the circuit, and the electricity flows through the flashlight bulb. The switch in the "off" position opens the circuit. Electricity cannot flow, so the light will not light.

• The wire in the flashlight is considered an insulator, and when the insulator is "on", you will have a closed circuit, lighting the bulb.

• When the switch is moved to the "on" position, it opens the circuit so the electricity goes through.

• There is a path, load, and conductors.

A student wants to test some materials to find out whether they conduct electricity or insulate electricity The student uses the following steps to get started...

step 1: Attach wire 1 to the negative end of a battery

step 2: Attach wire 2 to the positive end of the battery

step 3: Attach the open end of wire 2 to a light bulb

step 4: Attach wire 3 to the light bulb

step 5: ?

step 6: ?

• step 5: Connect a test material to the open ends of wire 1 and wire 3

  step 6: Make observations, and repeat step 5 with a different test material

  conclusion: If the bulb lights up, the material is a conductor If the bulb does not light up, the material is an insulator

• step 5: Connect a test material to the open ends of wire 1 and wire 3

  step 6: Make observations, and repeat step 5 with a different test material

  conclusion: If the bulb lights up, the material is an insulator If the bulb does not light up, the material is a conductor

• step 5: Connect the open ends of wire 1 and wire 3 to each other to complete the circuit

  step 6: Touch a test material to the completed circuit, and record observations

  conclusion: If the bulb lights up, the material is an insulator If the bulb does not light up, the material is a conductor

• step 5: Connect the open ends of wire 1 and wire 3 to each other to complete the circuit

  step 6: Touch a test material to the completed circuit, and record observations

  conclusion: If the bulb lights up, the material is a conductor If the bulb does not light up, the material is an insulator

A student is comparing two types of magnets The student asks five questions and then finds the answers to the questions by experimenting with the magnets. The results are shown in the table.

Based on the results, the student can determine Magnet 1 is a ​ (a)   and Magnet 2 is a ​ (b)   .

• electromagnet
• bar magnet
• powerful magnet
• refrigerator magnet
• non-magnetic magnet

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

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
