Alpha science classroom: How to Make Lightning

Views:5     Author:Site Editor     Publish Time: 2021-09-09      Origin:Site

When it rains, it is accompanied by lightning and thunder, which brings a lot of trouble to the children. Kids, do you know how lightning is formed? Today, Alpha Science Class teaches children how to create lightning through physical science experiments and helps children understand the reasons for the formation of lightning. Through kid's science experiments, children are no longer afraid of lightning.

Alpha Science Class: How to make lightning, the materials you need

  • Rubber glove

  • Plastic fork

  • Tin Foil

  • Wood or plastic cutting board

  • Styrofoam plate or rubber balloon

  • Head of hair or wool

  • Cool, low-humidity day (< 45% humidity, < 75 F temperature)

*Tips for Alpha Science Classroom: When children are preparing to do this interesting lightning experiment, they must be carried out under the supervision of parents to ensure that the children are the most important thing. In this way, children can learn about the magic of science in a safe environment.

Alpha Science Class: How to make lightning, what are the procedures

Step 1: First, children fold the tin foil around the plastic fork to make it look like a large spatula. Make sure it is as flat as possible without sharp corners.

Step 2: children put on rubber gloves and rub the styrofoam board or rubber balloon on their hair or wool with their gloved hands.

Step 3: children put the plate or balloon on the cutting board, and then use the gloved hand to pick up the foil spatula.

Step 4: children put the tin foil part of the spatula on the balloon or plate. Touch the foil with your other hand. what happened? How do you explain what you are seeing?

Step 5: children pull the spatula from the balloon or plate, and then touch it again. What happened this time? Are you looking forward to it?

Step 6: children try to use other materials. If necessary, use hair or wool to charge charged objects. When your hand touches the balloon, will your hand glow? Why is this happening?

Alpha science classroom reminds children: In order to get cooler results, please conduct this children's physics science experiment in a darkened room as much as possible, the effect will be more amazing and amazing!

Children's physical science experiment results

The alpha science classroom tells the children that when you touch the foil, you should have seen and felt the spark. When you remove the aluminum foil and touch it again, you should feel another spark. Your hands will not produce sparks, and most non-metal objects will not produce sparks when you touch a charged object. Any metal insulated by gloves that come into contact with live objects and hands will produce sparks.

Alpha Science Class: How to make lightning, the scientific principle behind

The alpha science classroom tells the children who are experimenting with static electricity. The static electricity you see is caused by the movement of electrons. Electrons are negatively charged, which causes them to be attracted by protons and repelled by other electrons. When you rub an object on your hair, it will do one of two things: it will either put electrons on the balloon or strip the electrons from the styrofoam board. This gives the balloon or plate a net charge, which means that the object has more electrons or fewer electrons than protons.

Metals are a special material because their electrons can move freely almost at will, instead of sticking to the molecules of the material. When a metal object is close to an object with a net charge, all electrons in the metal will be as far away as possible from the negative charge or as close to the positive charge as possible. Metals are called conductors. Your plates and balloons are insulators-they won't let electrons move where they want.

When your spatula is close to a charged object, the electrons either want to get close to the object or stay away from the object. When you lift your hand to touch the spatula, electrons will flow to you or to the spatula, depending on whether the spatula is in contact with the styrofoam board (facing) or the rubber balloon (away). Your skin is actually very conductive! After the electrons move, the tin foil has a lot of electrons in its place (near the charged object). When you remove the tinfoil scraper from a charged object, it suddenly has more or fewer electrons than it needs, so more electrons will jump out of your body to balance it. You can go back and forth for a long time like this because the electrons (or lack of electrons) on the charged object will not change.

Your hands will not produce sparks because your body provides a path to the ground. This means that when you bring your hand close to the balloon, all the extra electrons you need come from or enter the ground on which you are standing! Since you are wearing rubber gloves, the tin foil scraper cannot be grounded, so its charge cannot be equalized. When you touch it, you provide it with a path to the ground, allowing electrons to move and balance things. The earth has a lot of electrons to spare, and they move around.

So what makes lightning? Lightning occurs when the electric charge between the sky and the clouds on the earth differs greatly. Lightning is just a magnified version of the spark you see!

Isn't it amazing when kids make amazing lightning? Today, Alpha Science Classroom's experiments are very successful. When children know how to make Lightning, they will find that Lightning is no longer so scary, which is the charm of children's physical science experiments. What are the kids still waiting for? Come and learn more fun kid's science experiments, explore more secrets of lightning.
