The Impact of Society on Environment

The Impact of Society on Environment

The effects of society on the environment that are happening today are such as oil spills and acid rain. Acid rain is rain that becomes polluted by smoke from factories. The factories release poisonous smoke which contains harmful substances into the atmosphere which makes air polluted and when water cycle happens the water which evaporates into the air also become polluted. When the water falls down to earth as rain, it becomes acid rain. The acid rain did not just fall down on earth. It is poisonous and harmful. It will destroy some monuments or buildings and if it rains into a river or lake it can make animals or people living there died by using or drinking the water died.

Essay:

In this year at Panyarat High school. I have learned lots of things. Learning here is fun and interesting. What I like the most is doing experiments in the lab. Because I can learn to do many things more than my last school. My favorite lab experiment is the fish and shrimp lab. This year I got to join the science quiz bowl during the academic week. We got to learn many things that we don't know about science. I also like watching debate. Because I think debating is fun and we get to learn speaking English from it. I hope I can join debate club next year.





speed lab

1.         Describe how the ball rolls off the ramp at each height—discuss the effect of bouncing or other factors.
           
 If the ramp is high, the ball will bounce on the floor and time travel will be longer than the ramp with lower height.




2.         Discuss what is the fastest speed reached and any factors that could improve this.

 3 seconds, lower ramp




3.         Does the ball travel in a straight line, why or why not?

No. Because the floor is tilted.
