The Effects of Human Activity on Climate Climate is a natural activity that can be defined as the weather conditions prevailing in an area in general over a long period of time (which can include temperature‚ air pressure‚ humidity‚ precipitation‚ sunshine‚ cloudiness‚ and winds) (“Climate”). The climate has been a part of our environment long before humans came to study it‚ and really took it into consideration. Now through the many negative environmental actions created by humans through beneficial

pH pH means Power of Hydrogen or Potential of Hydrogen. pH is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. More acidic solutions have lower pH. More alkaline solutions have higher pH. Substances which are not acidic or alkaline i.e neutral usually have a pH of around 7. Acids have a pH less than 7. Alkalis have a pH greater than 7. There are a lot of ways for finding the pH of something. One way is to use litmus paper. The pH paper is able to tell how strong

Positive Effects of Volcanos Volcanic activity has many positive impacts on both the natural physical environment and on socio-economic activity. Positive impacts include the creation of new land‚ the creation of valuable natural minerals and ores‚ and the enhancement of countries’ tourism potential. Creation of new land: Volcanic activity can result in the creation of new land‚ when material from within the earth’s crust is ejected in the form of molten liquid‚ then cools and solidifies to created

of solutions and test their pH. Due to materials available pH strips were the only testing tools available. A table is setup to compare the strip color to its pH level. Four known solutions including bleach‚ lemon juice‚ soda‚ and baking soda were used. There was also an unknown solution in which the pH level was used to determine which solution it was. The pH scale is 1-14‚ a pH of 7 is neutral‚ less than 7 is acidic‚ and greater than 7 is acidic. Materials: * pH strips * 20 test tubes

courses offered by an educational institution”. In the world of education‚ do extracurricular activities still matter? Well‚ they are definitely a way to escape boredom as they strive to challenge an individual to do something new by overloading or filling up his schedule. And in truth‚ there are some anecdotes on different individuals cracking under pressure due to their participation in these activities. However‚ they cannot compare to the countless rewards that these ventures have to offer. After

The effects of the school activities to the learning achievement of the selected fourth year students of Liceo de San Pedro Academic Year 2009-2010. School activities are those sponsored by and usually held at school but that are not part of the academic curriculum. They often involve some time commitment outside of the regular school day. A school activity serves as a break of the students from their lessons. School activities include both extracurricular and co-curricular activities. School
