![]() ![]() Students will make their own thermometer based on this principle. This experiment introduces the idea that heat makes gases expand. Changing properties 1) Make your own thermometer: gases expand when heated ![]() Before starting, ask your students to think about what solids, liquids and gases actually are, in terms of their appearance and properties w1. When used together, they could occupy your class for a whole day, but they could also be split up and used in separate lessons. Image courtesy of videophoto /Įach of the five experiments relies on simple materials and is suitable for pupils aged 7-11 (although note that the reviewer suggested the article is suitable for pupils aged 10-13). After each experiment, in the manner of true scientists, we question our results and think about how we could improve our experimental design. We then examine how heat can convert gases, liquids and solids from one to another. In this small collection of experiments, we begin by investigating how heat alters the properties of the three states of matter. Why do elephants squirt water onto their backs? How does fog form? And why do trains make a ‘clickety clack’ noise? Your students will have answers to all of these questions once they have understood how heat affects solids, liquids and gases. Thanks for reading! I hope that we inspired you.From a homemade thermometer to knitting needles that grow: here are some simple but fun experiments for primary-school pupils to investigate what happens to solids, liquids and gases when we heat them. In the meantime, you might want to check out: I hope to get to many of them this winter. I have several activities within this area. Watch steam rise from a pot of boiling water.There are also several YouTube videos of ice melting with a time lapse. Do it in person in different temperatures. Ask your child to breath on to his hand a few times slowly: “What do you feel on your hand?” Explain: “The “wetness” is water vapor. Remind your child of how air exists even though we can’t see it. Gas – This one is fun because gas is invisible so you can’t technically see it.We also looked at different types of ice and snow images on Google Images. Liquid – Run a faucet, look outside on a rainy day or pour a pitcher of water into a glass.Plus, there are great hands on visual ways to demonstrate states of matter using water. It always has the same chemical properties no matter which state it is in. Water is the perfect example of introducing states of matter to kids because it can exist in three different states: liquid, solid & gas. Simple Introductory States of Matter Activity To end, have the children stand with fingertips lightly touching, barely brushing one another and say: “Gases are made from particles that are barely touching one another.”.Then have them stretch their arms while continuing to hold hands and say: “Liquids are made of particles that are further apart.”.Ask that they hold hands very tightly and say: “Solids are made of particles that are very close together.”.Gather together with your child or children and… Super hands on and concrete ideas! This activity introduces the concept of states of matter and would be great at circle time or in a large group. This post includes a Preschool Science Activity for Kids Introducing States of Matter.Ī wonderful resource for introducing science to kids is a book called Nurturing the Young Scientist: Experiences in Physics for Young Children by Meg Murphy Fedorowicz.
