1. Matter Presentation by Owen Hoffman

2. Introduction Matter is anything that takes up space and has mass. There are three states of matter solids, liquids, and gases. Matter makes up everything around you. Mass is how much matter is in one object.

3. Describing Matter Scientists describe matter using properties. Some properties are smell,taste, color, size, hardness, magnetic pull, and buoyancy. Buoyancy is the upward force in water. In other words it's what makes you float.

4. Solids Solids are all around you Chairs, desks, tables even your house is a solid. A solids particles are packed closely together. There only movement is vibration. A solid has a definite shape and size.

5. Liquids Some liquids cause the effect of buoyancy. A liquids particles move very slowly, and move more freely then a solid's particles. A liquid has no definite shape but does have a definite size.

6. Gases You can't see gases. A gases particles are fast and free. A solid has no definite shape or size.

7. Area Area is the number of square units that take up a surface. The formula for Area is length times width.

8. Perimeter Perimeter is the outline of a object. Perimeter is measure in feet not in square feet. The formula for Perimeter is add all sides.

9. Volume Volume is the amount of space an object occupies. Volume is measured in cubic units. The formula for volume is length times width times hight.

10. Weight Weight is the pull of gravity on an object. Let's say that you went to the moon. Your weight would change. This happens because the moon has less gravity.

11. Density Density is the amount of matter in a given space. Let's say a block of lead and a piece of cotton have the same mass, but the iron weighs more in grams. Even though they have the same mass the lead weighs more therefor the lead is more dense.

12. Elements Elements make up all types of matter. Elements are made of only one type of matter. On the periodic table there are many Elements. Some you might know of include Hydrogen, Gold, Silver, and Titanium.

13. The Atom Atoms make up everything chairs, bricks walls, books, and anything else you can think of. Atoms are the particles in a element. All atoms of one element are alike.

14. Mixture A mixture is two or more types of matter combined, but they both keep their properties. You can separate a mixture by filter, sorting, or evaporation. A solution is a mixture that is blended completely. One solution is salt water, and one

15. Alloys Alloys are used for lots of metals that need to be stronger. An alloy is to or more elements combined ( one has to be a metal ).

16. Compound A compound is formed when two or more elements combine chemically. The compound has none of the same properties as the matter it started with. Some examples are rust and salt.

17. Chemical Change A chemical change has different properties it started with. With a chemical change you start with one type of matter and end with another. Chemical changes either give of or take in energy.

18. Physical Changes A physical change begins and ends with the same type of matter. The four types of physical changes are change in shape, size, texture and change in position. Also a change in state is a physical change.
