Introduction Our group will be focusing on Polymers as our chosen topic. A polymer is a large molecule or a macromolecule formed by joining many repeated subunits. They may be naturally found in plants and animals known as the natural polymers or may be man-made called the synthetic polymers. Different polymers have a number of unique physical and chemical properties… Read more →
Global climate change
Understanding Earth’s energy balance is essential to understanding the issue of global warming. For example, the solar energy striking Earth’s surface averages 168 watts per square metre (W/m2), but the energy leaving Earth’s surface averages 390 (W/m2). Why isn’t Earth cooling rapidly? The emitted heat energy is mainly retained by the atmosphere thus the Earth does not cool rapidly even though the… Read more →
Make Ozone Great Again
Ozone
The ozone layer is an important layer in the Earth’s atmosphere. It is primarily contained in the stratosphere, about 90%. There are about 3 molecules of ozone per 100 million molecules which makes the concentration of ozone very low. It helps to absorb UV-B and all UV-C rays which are detrimental to human health and can cause skin cancer. Read more →
