In this fun video, concept of states of matter is explained by an amazing bubble experiment.
Science experiment about states of matter
There are three known phases or states of matter: Solid, Liquid and Gas.
Solid: – In a solid, particles are packed tightly together so they are not able to move much. These particles have very low kinetic energy.
Liquid: – In the liquid state, the particle of a substance have more kinetic energy than those in a solid. These particles are not held in a regular arrangement, but still very close to each other so liquids have a definite volume.
Gas: – Particles in gas states are have a great deal of space between them and have very high kinetic energy. They will spread out indefinitely.
Required Material: –
- Dishwasher soap
- Stirring stick
- Measuring cup
- Pour 4 cups of water in the container.
- Add half a cup of dishwasher soap in the water.
- Mix about 4 tablespoon of glycerine.
- Stir it well and make a solution.
- Now, take a straw, dip it in the solution and try to make a bubble in the air.
- If we will keep trying to make it larger, it will collapse and disappear. It shows that gases do occupy some space.
- One important thing, dry surfaces work like an enemy for bubbles. If a bubble touches anything dry, it will disappear.
- Try to make a bubble on a dry surface. After a certain size, it will collapse. But if we will sprinkle some water on the surface and then try to make bubble, it will stay for longer time.
- Even if we want, we can divide a bubble in many small bubbles but only with wet hands or straw.
- One more thing can be done. Make a big bubble. Then try to make on more bubble inside that one. One more in the second bubble and so on. But remember, do not let any dry thing touch your bubbles.
