Relationships with Electric and Magnetic Interactions - 3rd Grade Science

If one cloud is positively charged and one is negatively charged, lightning can be created even if there is a gap between the clouds. The particles are active enough to generate electricity through lightning, even if there is no contact between the positive and negative clouds. For lightning to be created, it does not matter if it is raining or not. It also does not matter if the clouds are touching. This is also true of oppositely charged objects on a smaller scale, like hair sticking to a balloon.

The reason this happens is because of static electricity. In the dryer, different fabrics rub together, the electrons from a cotton sock may rub off onto a polyester shirt. That's why clothes sometimes stick together and make sparks when you pull them apart.

Negative electrons and positive protons are opposite charges and are attracted to each other. An example would be if a balloon has the opposite charge as someone's hair, and they are held near each other. The hair will stand up and stretch out towards the balloon because the opposite charges are attracted to each other.

When someone rubs their feet across the carpet, there is a build-up of static electricity. Your feet are rubbing negatively charged electrons off of the floor, and it leaves you with a slightly negative charge. When you reach the positively charged knob, the electrons jump and cause the static shock that you feel on your fingertips. The opposite charges are attracted to each other.

Mr. Figueroa is providing an example of how two objects do not need to be touching for there to be an attraction. The static electricity generated by rubbing the balloon on someone's hair is the opposite charge as the charge on the paper. When the paper and balloon come near each other (not touching), the different charges are attracted to each other, and the balloon will cause the paper to "jump" or move.

When static electricity is created between a balloon and your hair, your hair is attracted to the balloon. If you rub the balloon on your hair and move it away slowly, your hair will follow the direction of the balloon and stick straight out. Your hair is the opposite charge of the balloon. Opposite charges attract, so the hair and balloon are attracted to each other.

The reason this happens is because of static electricity. In the dryer, different fabrics rub together, the electrons from a cotton sock may rub off onto a polyester shirt. That's why clothes sometimes stick together. They have opposite charges which are attracted to each other.

Negative electrons and positive protons are opposite charges and are attracted to each other. An example would be if a balloon has the opposite charge as someone's hair, and they are held near each other. The hair will stand up and stretch out towards the balloon because the opposite charges are attracted to each other. In this example, the two objects have the same charge, so they will repel each other. This can be felt with two magnets; when you try to push two North ends together, you can feel them pushing against each other as they repel.

Lightning is a form of electricity; it is static electricity. In the sky, if one cloud is positively charged and one is negatively charged, lightning can be created if the clouds are near each other. The particles are active enough to generate electricity through lightning, even if there is no contact between the positive and negative clouds.

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.

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.

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.

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.

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.

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.

If two ends of a magnet are placed near each other, and they have opposite charges, the magnets will move towards each other.

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.

This question is looking at the cause and effect relationship between magnets and other objects. Nails and sewing needles are metal, which would be attracted to a strong magnet. Placing the magnet over the items will pull them towards it.
