# 3rd Grade Science : Question cause/effect relationships of magnetism

## Example Questions

### Example Question #1 : Question Cause/Effect Relationships Of Magnetism

Nikki wants to get some hidden iron nails out of the pile of mulch in her backyard. Which of the following would be the best way to remove all the iron nails from the mulch, and why?

Have her dog dig through the mulch and take the nails out because they are attracted to the dog.

Sort through the dirt and get the nails with her hands because they are attracted to her hands.

Dig the nails out with a shovel because they are attracted to the shovel.

Use a strong magnet to pull the nails out because they are attracted to the magnet.

Use a strong magnet to pull the nails out because they are attracted to the magnet.

Explanation:

This question is looking at the cause and effect relationship between magnets and other objects. Iron nails are magnetic, which will be attracted to the strong magnet that Nikki uses. Placing the magnet over the pile will pull the nails towards it so they can be removed from the mulch. The other methods are time-consuming, will not work, or are not as efficient. Using the properties of an object and utilizing the relationships they have can assist in tasks.

### Example Question #2 : Question Cause/Effect Relationships Of Magnetism

Nick's mom spilled a drawer with thumbtacks, staples, and safety pins all over her carpet floor. Instead of picking up all of these sharp objects with her bare hands, what is a faster and safer way to clean up the mess and why?

Use a vacuum to pick up the items because then they don't need to be touched, and if the vacuum breaks, you can get a new one.

Be careful while picking up the items because they are sharp, and this is the easiest way.

Put on gloves to pick up the items because they are sharp, and they cannot poke through gloves.

Use a magnet to pick up the items because they are magnetic.

Use a magnet to pick up the items because they are magnetic.

Explanation:

The safest and fastest way for Nick's mom to pick up all of the items that spilled out of her drawer is to use a magnet. Staples, thumbtacks, and safety pins are all made of metal and magnetic. All of the items will stick to the magnet, and then Nick's mom can transfer the items on the magnet into the drawer. Nick's mom won't get poked by any of the items, and they will be cleaned up quickly. All of these items could damage a vacuum cleaner, she could still be poked through gloves, and just being careful is not the safest route.

### Example Question #3 : Question Cause/Effect Relationships Of Magnetism

Jake's mom made a pile of small, random household objects. Jake attached a magnet to the end of a string. If Jake goes "fishing" with his magnet in the pile of objects that his mom made, what kind of objects would he catch, and why?

Live objects because you catch live things when fishing.

Cold objects because they will be attracted to the magnet.

Silly things because this is a silly idea.

Magnetic objects because of the relationship of attraction.

Magnetic objects because of the relationship of attraction.

Explanation:

The only types of objects that Jake would "catch" are magnetic objects. Magnetic objects would stick onto his magnetic "fishing pole." Any objects that were not magnetic would not attach to the fishing pole. There is an attraction between magnets and items that have magnetic qualities. There is a relationship between magnets and objects with magnetic properties that cause movement and attraction.

### Example Question #4 : Question Cause/Effect Relationships Of Magnetism

Two magnets with opposite poles are placed two feet away from each other. As the magnets are moved closer together, what is most likely going to happen?

They will change colors as they get closer to each other.

They will not affect each other and remain where they are.

They will get attached as they get closer.

They will repel each other as they get closer.

They will get attached as they get closer.

Explanation:

Magnets have a magnetic field that attracts other magnetic objects, so because of this, they attach when they are close enough. If two magnets are moved closer and closer together, they will eventually reach each other's magnetic field and be very attracted to each other. Once this happens, the magnets will move towards each other and become attached.

### Example Question #5 : Question Cause/Effect Relationships Of Magnetism

Gregory and Morgan have two magnets. They are confused about why the magnets will not go together. They push them together with all of their might, but they still will not connect.

Why won't the magnets go together?

The magnets need to be activated before they will work correctly.

The magnets have opposite poles (charges) being pushed together.

The magnets are broken.

The magnets have the same poles (charges) being pushed together.

The magnets have the same poles (charges) being pushed together.

Explanation:

There is a cause and effect relationship between magnets that is being explored in this question. Gregory and Morgan are experiencing the effect of magnets having the same poles or charges faced towards each other. If the North end of both magnets or South ends of both magnets were pushed together, the magnets would repel. If opposite sides were being pushed towards each other, they would be attracted and connected.

### Example Question #6 : Question Cause/Effect Relationships Of Magnetism

Opposite ends of a magnet have opposite charges (poles). When put near each other, they will move __________ each other.

to the right of

towards

to the left of

away from

towards

Explanation:

If two ends of a magnet are placed near each other, and they have opposite charges, the magnets will move towards each other. Magnets have a magnetic field that attracts other magnetic objects, so because of this, they attach when they are close enough. If two magnets are moved closer and closer together, they will eventually reach each other's magnetic field and be very attracted to each other. Once this happens, the magnets will move towards each other and become attached.

### Example Question #7 : Question Cause/Effect Relationships Of Magnetism

Jake's mom made a pile of small, random household objects. Jake attached a magnet to the end of a string. If Jake goes "fishing" with his magnet in the pile of objects that his mom made, which object would he be most likely to pull out?

A dog biscuit

A penny

A soda can

A paper clip

A paper clip

Explanation:

The only types of objects that Jake would "catch" are magnetic objects. Magnetic objects would stick onto his magnetic "fishing pole." Any objects that were not magnetic would not attach to the fishing pole. There is an attraction between magnets and items that have magnetic qualities. There is a relationship between magnets and objects with magnetic properties that cause movement and attraction. In this case, the only magnetic object would be the paper clip. The other objects are not attracted to magnets.

### Example Question #8 : Question Cause/Effect Relationships Of Magnetism

Kelly and Daniel have two magnets. Every time the magnets are put near each other, they click together. The kids pull hard and separate them. They repeat this multiple times, and the same thing happens.

What is causing this relationship between the two magnets?

The magnets are broken.

The magnets have opposite poles (charges).

The magnets have the same poles (charges).

The magnets are not magnets.

The magnets have opposite poles (charges).

Explanation:

Magnets have a cause and effect relationship with other magnets and objects that have magnetic properties. The magnets in the example are attracted to one another because they have opposite poles or charges. When the North and South poles of the magnets are placed near each other, the different charges are attracted. If the same poles (North-North or South-South) are around each other, they will be repelled because like charges are NOT attracted to each other.

### Example Question #301 : 3rd Grade Science

What happens when two magnets repel each other?

They should push apart.

They push together.

Their magnetic field gets bigger.

They point to the North Pole.

They should push apart.

Explanation:

Magnets have a cause and effect relationship with other magnets and objects that have magnetic properties. The magnets in the example are attracted to one another because they have opposite poles or charges. When the North and South poles of the magnets are placed near each other, the different charges are attracted. If the same poles (North-North or South-South) are around each other, they will be repelled because like charges are NOT attracted to each other.

### Example Question #302 : 3rd Grade Science
