Magnetic Fields 1.3

They help us understand how compasses work and navigation.

They are only important for scientists studying physics.

Magnetic fields have no impact on daily life.

They are only found in laboratory settings.

Strong magnets attract and weak magnets repel.

Strong magnets repel and weak magnets attract.

Both strong and weak magnets repel.

Both strong and weak magnets attract.

A magnet has only one pole.

The north and south poles are at opposite ends of a magnet.

Both poles are located at the center of a magnet.

Magnets do not have poles.

Strong magnets move away from each other, weak magnets move toward each other.

Strong magnets move toward each other, weak magnets move away from each other.

Both strong and weak magnets move away from each other.

Both strong and weak magnets move toward each other.

To combine variables

To separate or set apart

To ignore data

To repeat tests

It makes the evidence stronger and conclusions more accurate.

It allows for more variables to be tested at once.

It speeds up the experiment.

It reduces the need for repeated trials.

Gather data that contradicts the claim

Provide stronger evidence

Ignore the claim

Repeat the experiment with isolated variables

It is the weakest evidence

It is the strongest evidence

It is irrelevant evidence

It is evidence that supports Barry's claim

It resulted from a test with multiple variables changed

It resulted from a test that isolated a single variable

It was the first evidence collected

It was the evidence that supported Barry's claim

The formation of rainbows

The operation of electric motors

The growth of plants

The melting of ice
