Matter matters By Manroop Thandi

What is Matter? Matter is a substance that occupies space. According to physics, matter consists of various types of particles each with mass and size Matter has different concepts: Chemical change, Changes of state, the particle model of matter, the Kinetic Molecular Theory, qualitative and quantitative properties, and pure substances.

Chemical Change Chemical Change is like the reaction of an experiment. It’s the change in matter that happens when substances combine to form new substances. Burning wood is an example of chemical change. The carbon from the wood reacts with the oxygen in the air which makes ash and the smoke.

Changes of State Changes of state is when there is a difference in the appearance, but there aren’t any new substances. Melting an ice cube is an example of change of state. Because it’s a solid turning into a liquid. The appearance has changed but the chemicals were not altered with. Some key points: Size, Shape, Colour, Texture, Odor, Mass, Weight, Density, and Volume.

The Particle Model of Matter Matter is made up of particles, that we cannot see. Those particles move all of the time they rotate, vibrate, and move from place to place.

Kinetic Molecular Theory Kinetic Molecular Theory is a way to explain what happens to matter when the kinetic energy changes (the behaviour). Energy makes the particles move, the more energy they have the faster they move. In a solid the particles vibrate since they are so close together. In liquid they can slip and slide, because they have a little bit of room. In gas they have lots of room so they can move in every direction.

Qualitative and Quantitative Properties Qualitative properties are characteristics of matter that can be observed or measured. Some key points to recognize: Colour, Malleability, Ductility, Crystallinity, and Magnetism. Quantitative properties are characteristics that can be measured. Some key points to recognize: Solubility, Conductivity, Viscosity, Density, Melting/Freezing Point, and Boiling/Condensing Point.

Pure Substances Pure substance is a substance that’s made up of one kind of matter. Elements and compounds are the 2 types of pure substances. Element is a substance that cannot be broken down or separated (Gold and Oxygen) Compound is a pure substance composed of 2 or more elements combined (water).

Solution Fluency Define: There are several different concepts to matter, and its hard to remember every one of them. Matter is very important because its all around us, so understanding it is a major thing. Dream: There are many different ways you can present this project like a document, a show, stop motion video, mind map, online poster, and a prezi. Debrief: The process making this presentation was okay, because I read the textbook and checked some websites. I think that the trivia game was a good way to end off my project, so that you can reflect on what you’ve learnt. I could have used a different platform to present my project.
