Calculate the density of each of your mineral samples. How could you use the densities to identify the minerals?
Ans: Density can be measured with the structure of the minerals. Different minerals will have different density.
Key Concept. Would density or color be more useful in identifying a particular mineral? Explain.
Ans: Density will be the same for the same minerals but color doesn't

Here are some example of the impact wich is made by people or society to the environment. The first one on my list is cutting trees. Trees are important for all living things, but things that are made of wood is also important for people. So what we can do is don't cut trees for an unnecessary purpose. Next up is air pollution, as human, we polluted the air by giving out carbon dioxide from car vehicle engine, factory and burning stuff.Last on our list is oil spilt. An oil spilt is the released of liquid petroleum hydrocarbon into the environment. This affects the animal life that lives in water which can cause death. That's it for the blog!!!!!!!!

1. Put the ramp against the seat of a chair. Place the ramp and chair so that the ramp points towards the hallway. Have your teammate on the other end of the hallway.
2. Place the ball bearing at the top of the ramp.
3. Lift the ramp 20 cm and release the ball bearing
4. Time how long it takes to travel 5 meters.
5. See how far it will go..
6. Repeat the experiment three times for each height then do 40 cm, 60 cm, and 80 cm.
Time to travel 5 meters
Observation: I Have observe that the higher the starting point of the ball is, the shorter the ball travel. But not all the time it is like that.
1. Describe how the ball rolls off the ramp at each height—discuss the effect of bouncing or other factors.
Ans; So when it start at 20 cm, the ball did't bounce much so it can go peaty far, the higher the ball is released the shorter the distance the ball travel, it is because the effect of bouncing. If it is a bouncing it would be a good effect on it but this is a plastic ball.
2. Discuss what is the fastest speed reached and any factors that could improve this.
Ans: The fastest speed is 3 second /300 cm
3. Does the ball travel in a straight line, why or why not?
Ans: No because the surface of the ground is not flat, and ball can roll anywhere although the surface of the ground is flat.
