Learn About Electricity
A good definition for K students would be: “Electricity is one form of energy that gets its power from the flow of electric charges (electrons and protons), also called electric currents (if the child has a background in atoms, they’ll be familiar with the concept of electrical charges).”. Jun 15, · Electricity is a type of energy that can build up in one place or flow from one place to another. When electricity gathers in one place it is known as static electricity (the word static means something that does not move); electricity that moves from .
Do you believe in magic? Science can how to explain electricity to kids every seemingly fantastic phenomenon! Have you ever rubbed kkids inflated balloons to stick them together? Did you ever find scraps of paper what festivals are on this summer to your sweater in the winter?
Your kids may have also seen these things happening. Here is how to explain static electricity to kids. All things are made from atoms. These atoms contain chargesboth positive and negative, known as protons and electrons, respectively. For the puritans: there are neutrons as well, which have zero charges, but they are not relevant to this discussion. Protons carry a positive charge, whereas electrons have a negative charge. Opposite charges attract each other whereas like ones repel.
When electrciity is a balance between the charges in an atom, the atom remains neutral. However, rubbing an object with some specific things like cloth or plastic can lids electrons kifs shift from the plastic or rubber object. Well, this was my question too, when my kid touched a doorknob and felt a mild shock. I knew words would not be enough to explain the concept. Therefore I decided to do a few fun activities with him instead!
You can learn from my experiments and use it to explain this critical scientific principle to your children! All you need is a light plastic bag, plastic rod, and a piece of cloth to perform this activity. After you rubbed the plastic bag and rod with the cloth, they become negatively charged. Since they both carry a negative charge, they repelled from each other.
This opposite force made the plastic bag move away from the rod. With static electricity, you can make an aluminum can roll. Take a plastic rod, an aluminum can, and a piece of cloth.
After rubbing the rod and can with cloth, the rod becomes negatively charged. Explaun the can remains positively charged. Since both the items are carrying opposite charges, they tend to attract each t. This is why the explai is drawn towards the rod. With static electricity, you can even make your hair stand. To watch the magic happen, all you need is a balloon and a piece of cloth.
After rubbing with a cloth, the balloon becomes negatively charged. Since we did not touch the hair, it was charged positively. This is why the balloon attracts the hair towards itself. You can easily separate pepper how to treat dry ends of hair salt with explaln electricity.
You will need some small items from your kitchen pantry to start this activity. All you need is some salt, pepper, a plastic spoon and a piece of cloth. When you take a plastic spoon and rub it with a cloth for 40 to 50 seconds, the spoon gains electrons.
Now since salt and pepper granules are positively charged, they tend to get attracted towards the spoon. But since pepper is lighter than salt, it jumps quickly to stick to the spoon. You thought only you could dance? No, your kitchen plates can dance too. Check out this activity. But first, gather a few items such as two styrofoam plates and a piece of cloth. Here again, static electricity played a role. Electrricity you rubbed the plate with a cloth, it gained some electrons from the cloth and became negatively charged.
When you tried to place the negatively charged plate on the positively charged one, they repelled each other. I hope they helped you explain static electricity to your little one. However, in wlectricity you still have a doubt or two, here are answers to some frequently asked questions:.
Not all gadgets are vulnerable to static electricity. Electronic chips found in computers are sensitive to static electricity. This is why we store them in unique bags. Yes, there are quite some uses of static electricity in our daily lives. It is used in photocopy and printing machines where static electric charges attract the ink to the paper.

1. Keep It Simple and Fun
Aug 17, · Your kids can use the power of static electricity to roll an empty soda can across the floor. Keep them interested past the science lesson by laying down some masking tape to create a finish line and let them race each other. I love this activity because . In some elements, there are electrons on the outside of the atom that, when a force is applied, can come loose and move to another atom. When a bunch of atoms are together and electrons are moving from one atom to the other in the same direction, this is called electricity. Electricity is . Electricity flows from the power source, in a loop or a circuit, back to the power source. This means that the electricity must start and finish at the same power source. If the circuit is not complete (i.e. if the loop is not closed) then electricity cannot flow through it properly. Which one of these loops allows electricity to flow?
Love your site! So many ideas and very kid friendly. Thank you so much for providing this content. My answer, at the time, should have been no — but with a name like Siobhan how could I turn her down. Turns out a few email exchanges later, I find out that she is related to half of Ireland. Shockingly no pun intended I also had a couple of hours free — and so I got to work.
A power source provides a steady flow of electrons. Larger appliances like heaters and large computers usually get their power from the mains. But small batteries cells can also be a power source.
The problem with electrical energy obtained from battery power though, is that battery power eventually runs out and the battery has to be thrown away or recharged.
In other words other sources of energy are needed to produce electricity. Electrical current needs a PATH on which to travel. Another name for this path is a circuit. Electricity flows from the power source, in a loop or a circuit, back to the power source. This means that the electricity must start and finish at the same power source.
If the circuit is not complete i. A load is a device that uses electricity like a buzzer of a light blub. The load needs electrical energy to be able work. The electric current from the power source flows from one place to another through the wire of a circuit.
These metal wires conductors are often wrapped in plastic insulators so as to stop the electric current flowing into objects that touch the wire. If electricity flows through an object, then scientists say the object conducts electricity, and they call it a conductor. Metals are very good conductors. A small bit of energy is released as heat when electricity flows through the conductor. Plastic, wood and rubber are all very good insulators. You can increase a circuit by increasing the length of the connecting wire.
What do you think will happen to the light bulb as the wire gets longer? How about as the wire gets shorter? Switches allow you control over the circuit. You can stop the flow of electricity by breaking the circuit. Here are some instructions to help you do some science at home and make your own switch. Sometimes circuits are drawn using special symbols. These symbols make it faster and easier to draw circuits and once you understand what the different symbols stand for, these diagrams are very easy to understand.
Here is a chart to help you to understand the different circuit symbols that are used in when drawing the different components of the circuit. Whenever two components are joined together in the same circuit, there are two different ways they can be wired: in series or in parallel. In the in series circuit the components are joined together in one bigger circuit i.
Electricity passes first through one component first then the next one. A disadvantage of the in series circuit is that when one component malfunctions, the other components will stop working. A major advantage of parallel circuits is that if one component malfunctions, the other continues to function. Batteries can also be connected in parallel or in series. But, if you are using more than one battery in a circuit they need to all face in the same direction to work.
If two batteries are connected in series, then the voltages add together. I received an email the other day saying: Love your site! Electricity can be used to perform work such as: Heating our homes or our food electrical energy is converted into light and heat energy Lighting our lamps electrical energy is converted into light and heat energy Powering our computers electrical energy is converted into light, heat and sound energy or Powering a motor electrical energy is converted into movement, heat and sound energy.
But where do these items get their electricity? All appliances, whether small or large, need a power source. What is a power source? What is an electrical circuit?
Which one of these loops allows electricity to flow?
