                                  Volume, density and mass

   Today it is my first time in the lab in this semester.My friends and I do a lab about getting volume from adding water to the beaker with selected rock and the water will increase that extra amount of water is the volume of that rock.Then, my friends and I  measure the rock mass by many types of measure machine.Lastly, We find the density

Sample No.    Weight of Grams    Volume ML    Density g / ML
       12                    149.94g              201 ml                0.74g

Impact of environment

           Society impact on the environment for me is when any activities or any operation in their life that affect that environment in a bad way.There are many examples such as air pollution, global warming, or Acid rain.
                              Acid rain is any form of precipitation with acidic components.Running of factories and automobiles due to human activities are few other reasons behind this activity are some causes of acid rain.The effect of acid rain on the environment is greater than its impact on lakes, streams, wetlands, and other aquatic environments. Acid rain makes waters acidic and causes them to absorb the aluminium that makes its way from soil into lakes and streams.                                 Global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.The industrial activities that our modern civilisation depends upon have raised atmospheric carbon dioxide levels is one of the human activities that cause this.

                            Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mould spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities which is all made from human activities.This will cause air quality to be worse.
