  11. 11. Matter <ul><li>: anything that has volume and mass </li></ul><ul><li>ex) water, air, sand </li></ul>ㅡ Anything that takes up space and has mass is a matter. Therefore, a human and a car are matters. Back Click Here for Explanations of 2 Types of Matter.
  12. 12. Not Matter <ul><li>: anything that doesn’t have mass or volume </li></ul><ul><li>ex) thoughts, sound, emotion </li></ul>ㅡ Light is energy, not a matter. It doesn’t have either volume or mass, which are important properties of matters. Back
  13. 13. Pure Substance <ul><li>: a type of matter that consists of only one type of particle </li></ul><ul><li>ex) copper, water, aluminum </li></ul>ㅡ Water is always around us. It consists of only one type of particle, H2o, which is combination of two hydrogen atoms and one oxygen atom. Back Click Here for Explanations of 2 Types of Pure Substance.
  14. 14. Mixtures <ul><li>: matter that has more than two pure substances </li></ul><ul><li>ex) iron mixed with sulfur, salt water, salad </li></ul>ㅡ There are many different kinds of books on my bookshelf. They all have different colours and thicknesses, which makes it a mixture. Back Click Here for Explanations of 2 Types of Mixtures.
  15. 15. Element <ul><li>: a pure substance that cannot be transferred into any simpler form </li></ul><ul><li>ex) copper, aluminum, silver </li></ul>ㅡ Aluminum foil is mostly made of aluminum which is an element, Al. Back
  16. 16. Compounds <ul><li>: a pure substance that is composed of two or more elements </li></ul><ul><li>ex) water </li></ul>ㅡ Nail polish remover is mostly composed of acetone which is a compound, CH 3 COCH 3 . Back
  17. 17. Heterogeneous Mixtures <ul><li>: a mixture that has uneven composition of large, visible particles </li></ul><ul><li>ex) water mixed with oil, salad, pencil case full of pens </li></ul>ㅡ The school wall is mixture of different kinds of rocks and cement, and you can actually distinguish the particles pretty easily. Back
  18. 18. Homogenous Mixtures <ul><li>: a mixture that has even and microscopic composition of indistinguishable particles </li></ul><ul><li>ex) coffee, hot chocolate, salt water </li></ul>ㅡ The mixture of ink and water is a good example of homogenous mixture because you cannot distinguish water particles and those of ink. Back
  19. 19. Mass <ul><li>: how much matter is in an object, which doesn’t change like weight </li></ul>ㅡ Although those two objects have the same volume, the left one is more massive. That is because the left one has more amount of matter inside than the right one does. Back
  20. 20. Volume <ul><li>: the amount of space an object takes up </li></ul>ㅡ Inside the plastic bag, there is air. The plastic bag takes up space and even though air is invisible, it is proven that air has volume. If air didn’t have volume, there would not be any balloon or ball. Back
  21. 21. Density <ul><li>: the amount of matter in an unit volume of an object </li></ul><ul><li>* How to Calculate Density: Mass/Volume </li></ul>ㅡ From the photo, you can say that the yellow clay is floating on the water. This is because the yellow clays is less dense than the eraser. That means, the eraser has more matter in its unit volume. Back
  22. 22. Viscosity <ul><li>: the degree of resistance to flow from one spot to another of a liquid or gas; how thick a liquid or gas is </li></ul>ㅡ As you can see from the photo, ketchup is dangling instead of falling right away. It is because ketchup is viscose, resisting to flow. Back
  23. 23. Conductivity <ul><li>: the ability of a matter to transmit electricity or heat </li></ul>ㅡ The pot on the fire conducts heat, heating whatever inside of it. In this photo, there is water boiling inside the pot. If the pot didn’t conduct heat at all, it would be impossible to cook using it. Back
  24. 24. States <ul><li>: the physical property that shows in which form a matter exists: solid, liquid or gas </li></ul>ㅡ These are the three states of water: ice, water, water vapor. The ice is solid in a certain shape, water is liquid in a pot, and water vapour is gas as you can see it coming out. Those bubbles are because of the water vapour escaping the boiling water to be free in the air. Back
  25. 25. Physical Change (2 ex) <ul><li>: change that cause a change in state or form of a matter, but not a change in the actual substance. </li></ul><ul><li>ex) ice cream melting </li></ul>ㅡ In the first photo, a sheet of paper is torn apart, which changed the form of the paper. In the second photo, water vapour was blocked by the lid of the pot and cooled down due to the cooler lid. This is the change from a gas to a liquid. Back
  26. 26. Chemical Change <ul><li>: change that happens when a substance changes into one or more different substances. </li></ul><ul><li>ex) colour change of leaves </li></ul>ㅡ Photosynthesis is chemical change, because the colour changes into green creating energy. The browning of an apple is chemical change for the same reason. Back
