3. MATTER: Matter is anything that has mass and volume. There are four state of matter; solid which has strong bonds, liquid which has weak bonds, gas which has no bonds, and plasma which is ionization.
4. MATTER: This picture is bobbles. The bobbles has mass and volume, it’s just a clear air balloon. This balloon is a air bag. Air is a gas and it’s matter too. You can see when you blow a balloon. It has mass and volume. If it doesn’t then how can the balloon get bigger? This wood made human represent a real living human. A person is also a matter, because it has mass and volume.
5. NOT MATTER: Something that doesn’t have mass and volume. Which means it’s not solid, not liquid, not gas, and not ionization. Light is not matter. It’s a type of energy that doesn’t have mass and volume. This pictures represent the heat. Heat is not matter because it’s one type of energy. Sound is not matter. It doesn’t have mass and volume.
6. PURE SUBSTANCE Object of atoms that make matter. Matter divide into two main things; pure substances and mixtures. Pure substances divide into two groups; elements and compounds. Mixture also divide into two groups; homogeneous mixtures and heterogeneous mixtures.
8. ELEMENT: Consists only one type of atom, so elements can’t be break down. This is called periodic table of elements. It shows the 117 elements and it’s also divide into eight different groups.
9. Elements: Fire and water are both the well known elements. Fire and water they can’t be break down again, that ‘s why it’s called elements. Fire(left) water(right).
10. COMPOUND: A substances that consists of two or more elements. This is some examples of compounds, like NO is nitrogen oxide and it is made by two different elements. Therefore it’s called compounds.
11. Compounds: As this cube for example, this many different colors of squares made one perfect cube. It’s not compound, but it is a perfect definition for compound. This night sky is the same as the cube. Many different type of lights and houses mixed together made a perfect image of compound. The houses together made a city.
12. MIXTURE: Two or more substances mixed together, combination of two or more substances.
13. Mixtures: This are all examples of mixture. Salad is full of many different vegetables and fruits in it. The nuts have more than four types in there. The glass ball and the pencils are the same as the other one. This things can be call as the mixtures in our life.
14. HETEROGENEOUS MIXTURE: Many different substances that are mixed together. Use this picture as example, this two different type mixed together made this heterogeneous mixture.
15. HOMOGENEOUS MIXTURE: The substances that have the same members or parts that are mixed together. When things are completely dissolved. This ice tea is a homogeneous mixture. The tea and sugar and many other curatorial are mixed together but you can’t actually see them. This is homogeneous mixture. The same ones are together, the red with red, the blue with blue.
16. MASS: The amount of matter. Mass is the amount of matter. In this picture, there are 16 “M”s, the mass of m&m is 16.
17. VOLUME: The amount of space something takes up. Even though the picture is about math but what it basically means the space something is taking.
18. SUSPENSION: Two substances that can’t be mixed. This one has oil and juice, look carefully you can see the layers. It’s because it’s suspension. Because it’s suspension so the water can’t be mixed with the oil. Tomato juice and water and wax had made three layers, which meant it was suspension like the other two pictures.
19. EMULSION: A liquid or cream which is a mixture of two or more liquid. This coffee is the mixture of milk, water, sugar, cream and coffee beans, which can be called as emulsion.
20. MECHANICAL MIXTURE: When two or more different materials are mixed together but are visibly not wholly one. Pizza(left), and pie(right) can be called as mechanical mixture. Pie and pizza are one but not wholly one, they can be separated again.
21. REVERSIBLE CHANGE: The change that change an object back to its original form. The earth will be reversible change. Like the earth before, full of trees and oxygen's. People will change the world that is full of garbage into a beautiful world again. That is reversible change because the earth can change back to its original form.
22. NON- REVERSIBLE CHANGE: The change that can’t change back to its original form. The thing like coffee they are already made, and it can’t be get back to it’s original form, it’s called non-reversible change.
23. 2 EXAMPLES OF PHYSICAL CHANGE: Water solidified into ice when it’s cooled Water turn into gas when it’s heated. Physical change: In a substance doesn't change what the substance is.
24. 2 EXAMPLES OF CHEMICAL CHANGE: When there are salt added in a cup of water its chemical change. When a piece of soap dissolved in a cup of water its chemical change. Chemical change: Where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed. Salt water. Soap water.
