be very cloudy. Once filtering the contaminated water‚ the water will be clear and purified. Second‚ I will experiment water treatment and filtering. I predict that once the contaminated water is treated and filtered that it will leave me with less contamination or none at all. Then for the last experiment‚ I will determine the difference between bottled water and tap water to discover any contamination. I predict that the tap water will be the most contaminated and with the most chemicals in it‚

Lead is an element that occurs naturally in the environment. Small amounts of lead can be found in the earth’s crust. Most people know it to be harmful to humans but research shows that it does have some beneficial uses. Lead is found in the air‚ soil‚ water‚ and inside our homes. Much of the exposure that we receive comes from our daily activities‚ such as some types of industrial facilities‚ the use of fossil fuels and past use of lead-based paint in homes. Lead and its compounds have been used

It was not as brown as the other water(s) but that may have been

affects the quality of water‚ agents of water contamination and how water impurities can be removed for water quality. There are two visible features of contaminated water; colour and smell. Contaminated water usually has unusual smell and coloured. Invisible factors affecting water quality are sources of water. For instance; tap water is more contaminated than bottled water. Agents of water contamination include; oil‚ vinegar‚ laundry detergents and other human activities such as mining. A’o‚ L. in his

INTRODUCTION Radiations are energy in the form of waves or particles. They are of two forms‚ ionizing radiations and non-ionizing radiations. Ionizing radiations are radiations of short wavelength and high energy which causes atoms to ionize. Examples of ionizing radiations includes: x-rays‚ gamma rays‚ ultra violet radiation. Non-ionizing radiations are radiations of long wavelengths and low energy. Examples of non ionizing radiations includes infra-red rays and visible lights e.t.c Effects of ionizing

The people were evacuated‚ but the area was completely polluted. The stock started eating plants that grow in polluted soils and the meet that was taken from the cow and eaten by humans had an accumulation of toxins. To prevent this the state start planting green plants in the polluted soil to remove the toxins

stress—whether it be resistance to pests‚ severe weather such as frost or drought‚ disease‚ or from chemical compounds. For example‚ plants can be genetically engineered to produce their own Bacillus thuringiensis (Bt)‚ a bacterium that occurs naturally in the soil in which disrupts the digestive systems of insects upon consumption.i An additional benefit is the possibility for farmer’s to use fewer pesticides in treating GM crops. Non-GMO crops are significantly more affected by pests‚ as traditional crop
