1. Matter properties

2. Buoyancy Buoyancy is the upward force of water,another liquid,or air keeps things afloat.

3. Mass Is the amount of matter in an object and is measured in units of grams or kilograms

4. Solid What is a solid? A solid is made of matter and particles that are packed together tightly and there movement is vibrating.

5. Liquid What is a liquid? a liquid has fixed size and particles. The particles move slow and freely.

6. Gas What is a gas? A gas has particles and no fixed size.the gas particles move fast and free

7. Matter Matter is anything that takes up space and has mass.the three states of matter are solids,liquids, and gas.

8. Area The amount of space inside a flat object. The formula to find area is L x W.

9. Perimeter Perimeter is measuring the distance around an object.

10. Volume Volume is the amount of space occupied by an object measured in three dimensions.

11. Density Is a measure of mass per volume.

12. Mixture Solution is a mixture that is blended completely.two or more types of matter combiner.examples of a mixture are: mix vegetables,salt water, and grape juice.each type keeps it's original properties. A mixture can be separated 1.sort by 2.fiter 3. Evaperation.

13. Compound Each element loses it's property when combined. Froms when two or more elements are combined chemically. Examples: salt, sugar, and rust.

14. Alloy Mixing metal with another elements can make it stronger. A mix of two or more elements one must be metal.

15. Atoms Atoms of one elements are all alike. Smallest part of an element.

16. Elements Elements are made up of only type of matter.Elements are the building blocks of matter.Examples:gold,silver,o xygen.

17. Chemical change Involves energy either takes in or gives of energy.Changes in matter itself (start with one kind of matter and end with a another.

18. Physical change In a physical change heat energy causes matter to change state. There are four types of physical change 1.Change in size and shape 2.change in texture 3.change in position and last but not least #4.change in state.
