The document summarizes key concepts about velocity, speed, simple machines, and states of matter. It defines speed as how fast something is moving without direction, while velocity includes both speed and direction. Simple machines are described as devices that make work easier, including levers, pulleys, and inclined planes. The three states of matter - solid, liquid, and gas - are defined based on properties like density, compressibility, and ability to flow. Examples and pictures are provided to illustrate concepts. The document serves to teach these scientific concepts and check understanding through concluding questions.

1. Sciencefinal project E.Q 1:what is the difference between velocity and speed?

2. What is speed ? Speed is how fast something is moving. 3/4/2010 math 2

3. What is velocity ? Velocity is speed in a specific direction. 3/4/2010 math 3

4. Speed Speed is distance over time, because the distance you are going and the time. 3/4/2010 math 4

5. velocity In velocity you always have to have speed , directions , and time but you don’t have to have mass. 3/4/2010 math 5

6. E.Q 2:what is simple machines A simple device that makes work easier for you to do. such as a lever, pulley, or inclined plane. 3/4/2010 math 6

7. What is a lever ? a rigid bar pivoted on a fixed point and used to transmit force, as in raising or moving a weight at one end by pushing down on the other. 3/4/2010 math 7

8. What is a pulley? essentially of a wheel with a grooved rim in which a pulled rope or chain can run to change the direction of the pull and thereby lift a load. 3/4/2010 math 8

9. What is a inclined plane? A plane set at an angle to the horizontal, especially a simple machine used to raise or lower a load by rolling or sliding, and it cause you change directions. 3/4/2010 math 9

10. What is a wedge A piece of material, such as metal or wood, thick at one edge and tapered to a thin edge at the other for insertion in a narrow crevice, used for splitting, tightening, securing, or levering. 3/4/2010 math 10

11. e.Q 3:what is the state of matter? State of matter have 3 parts which is solid liquid and gas. 3/4/2010 math 11

12. gas The state of matter distinguished from the solid and liquid states by relatively low density and viscosity, relatively great expansion and contraction with changes in pressure and temperature, the ability to diffuse readily, and the spontaneous tendency to become distributed uniformly throughout any container. 3/4/2010 math 12

13. solid Of definite shape and volume; not liquid or gaseous 3/4/2010 math 13

14. liquid The state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility. 3/4/2010 math 14

15. Picture of a liquid 3/4/2010 math 15

16. Picture of a solid 3/4/2010 math 16

17. Picture of a gas 3/4/2010 math 17

18. questions Do you learn any thing I taught you? Your answer: 3/4/2010 math 18

19. question Do you know formula for speed ? Distance over time or miles per hour? 3/4/2010 math 19

20. end Thanks for listening and learning 3/4/2010 math 20
