These ideas are the perfect compliment to our 30 Science Experiments for kids in our shop!ĭiscover where rain comes from with a simple prep Water Cycle in a Bag. When the paper hits the table after being repelled it'll lose it's excess charge to the table and the whole thing can repeat.These must-try weather activities for kids are fun, hands-on ways to teach about temperatures, clouds, rain… even tornadoes!! Whether you’re in need of a quick kids’ science project or are looking for something more crafty, we’ve got you covered. So: first it's attraction by polarization, then the paper is charged by conduction (contact) and then it's mutual repulsion. But, upon contact, some of the excess electrons on the charged balloon migrate into the uncharged paper and it becomes negative too and is repelled. Since the positive side of the neutral but polarized paper is closer to the negative balloon the paper "jumps" to the balloon. The paper is neutral but, when close to the balloon *some* of the electrons in the paper are repelled to the far side of the paper, leaving it still neutral but polarized (one side is positive, the other is negative). The balloon acquires negative charge from the hair and becomes a big, negatively charged object. Great experiment for sure, but the charge isn't alternating between positive and negative. Make Jumping Goop – Use cornstarch and oil to make a liquid that is statically charged. Again, these experiments use supplies from around the house. Static Electricity Experiments with Balloons – Make the balloons repel each other, and build an electroscope. Need more Static Electricity Experiments? Static electricity does not build up very well on a humid day because the charged particles are likely to attach themselves to water molecules in the air. They now attract each other because of their opposite charges. However, when you rub two things together (like a comb and hair), some electrons move from one to the other, causing one item to have a positive charge and the other to have a negative charge. The charges (negative and positive) are usually balanced in each atom, and so the atoms are not charged, and the object is not charged. Then watch the WATER BEND! WOW!Īll matter is made up of atoms, and all atoms are made up of protons (positive charge), neutrons (no charge), and electrons (negative charge). Hold the comb or the balloon very close to the stream of water, but not touching it. Then charge either the comb or the balloon by running it through your hair. The smaller, the better, but you do need the water to be running consistently and not just dripping. Turn on the faucet with a very small stream of water. This experiment can be done with a comb OR a balloon. We did this impressive science experiment in my fifth grade class, and I have remembered it all these years! This was really pretty amazing to watch! You can literally watch the little pieces of pepper fly up to the comb.Įxperiment #2: Bending Water Static Electricity Experiment Step 3: Hold the statically charged comb over the dish, and the comb will attract the pepper causing it to jump up out of the dish. Step 2: Have your child give a plastic comb a static charge by running it through their hair.īy the way, we discovered that if one person charges the comb and then hands it to another person, it does not stay charged! The person who wants to do the experiment must also be the one who charges the comb! Step 1: Put some salt and pepper in a small dish. If the weather is excessively humid, you may not get good results.Įxperiment #1: Salt and Pepper Static Electricity Experiment But, it’s perfect weather for static electricity science experiments! You can do these experiments any day, but they definitely work best when the air is dry. Our weather has been so cold and dry lately – not my idea of perfect weather. Demonstrate the power of electricity with these easy static electricity science experiments! There are two activities to try with items from around the house: a fun salt and pepper static electricity experiment and a bending water static electricity experiment.
