Eric McKenzie Geophysical Science Honors February 14th‚ 2014 ACID RAIN 1. Acid rain is rainfall created by pollution in the atmosphere. When the rainfall occurs‚ it almost always causes harm to the environment. 2. Acid rain is caused by the release of certain compounds into the air‚ including sulfur dioxide and nitrogen oxides. These compounds mix and react with chemicals such as oxygen and water and form acid rain. 3. Acid rain can harm the environment by acidifying lakes and streams‚ which greatly

Franklin 1 Jonathan Franklin Allen Layne Criminal Investigations 18.OCT.2013 Investigations And The Principles A successful crime scene investigation depends deeply on the collection and analysis of various kinds of evidence. Forensic scientists rely on the classification of certain evidence and they have different ways of dealing with it. One major difference is biological and physical. Physical evidence refers to the collection of anything at the crime scene that comes

Aim. The aim of this investigation is to find out how Slaters react to an increase or decrease of the temperature in its surroundings. Hypothesis The speed of the Slaters will increase when the temperature of its environment is increased or decreased from its preferred range‚ so it ensures that they spend less time in unfavorable conditions to avoid desiccation. Method 1. This experiment is done using a water bath to change and control the temperature being trialed. The water bath will have

PENDULUM INVESTIGATION Aim of the investigation The aim of the pendulum investigation is to see what will happen if I change a variable whilst I swing a pendulum and see the effect which it has on the pendulums time to complete one whole swing (from where it starts‚ to the opposite end‚ and back again). This will give me an insight into what will effect the time of the swinging of the pendulum‚ be it weight‚ string length‚ the angle‚ or the swinging point. Planning my investigation I will
