objects at a distance? Choose TWO correct answers.

• Bring a magnet close to metal objects and see if they move.

• Touch a magnet to metal objects and see if they stick.

• Touch a magnet to plastic objects and see if they stick.

• Bring a magnet close to plastic objects and see if they move.

When planning a magnetism investigation, what is a well-defined question that can

be asked?

• What color is my favorite magnet?

• How does the distance between a magnet and an object affect the magnetic

  force?

• How many magnets can I find at home in 5 minutes?

• What can you do to determine which magnet is the largest?

Look at the picture showing different objects with the same magnetic properties that

students accidentally dropped behind a bookshelf. Students cannot reach the objects

with their hands.

How can students test magnets to see which magnet they can use to pick up the

objects behind the bookshelf?

Choose the words to complete the statements.

Place the _________ object on the table. Next, place different size magnets

_________ the object to see which it will attract to.

• largest; near

• largest; on

• smallest; near

• smallest; on

A student wants to test which type of magnet (bar magnet, disc magnet, or

horseshoe magnet) is the strongest. The materials needed during this investigation

are as follows:

● Different types of magnets (e.g., bar magnet, disc magnet, horseshoe magnet)

● A set of paperclips (or other small metal objects)

● A ruler or measuring tape

● A recording sheet or science journal

● Labels for each magnet type

The steps for the investigation are below. Steps 1 and 6 are in the correct order. Put

steps 2 through 5 in order so the student will be able to conduct the investigation.

The steps for the investigation are below. Steps 1 and 6 are in the correct order. Put

steps 2 through 5 in order so the student will be able to conduct the investigation.

Step 1: Label each magnet so you can identify them during the investigation.

Step 6: Record your observations and results in your science journal.

• Step 4: Measure the distance from the magnet to the farthest paperclip it attracts.

  Record this distance.

• Step 5: Repeat the test three times for each magnet to ensure accurate results.

• Step 2: Place the magnets in a starting position, such as on a table, with enough

  space between them.

• Step 3: One at a time, bring each magnet close to a set of paperclips and see how

  many paperclips it can attract and hold.
