The Observation of organism in a drop of pond water (Paramecium) under LPO and HPO Compound Microscope Doreenda A. Sabao BS Biology I-A .Lab 1 August 01‚ 2013 INTODUCTION A pond is a body of freshwater smaller than a lake. Ponds are naturally formed by a depression in the ground filling and retaining water. Streams or spring water is usually fed into these bodies. They can also be man-made ponds which can be created by damming a stream‚ digging a hole. Ponds are usually

WATER CONSERVATION Water conservation encompasses the policies‚ strategies and activities to manage fresh water as a sustainable resource to protect the water environment and to meet current and future human demand. Population‚ household size and growth and affluence all affect how much water is used. Factors such as climate change will increase pressures on natural water resources especially in manufacturing and agricultural irrigation. The goals of water conservation efforts include as follows:

Have you ever dropped oil on your hands and tried to wash it off? What happens? Does the water slide off? Or what about when a drop of oil falls in a glass of water? Why does it float to the surface‚ and not mix? The answer to this is simple: polarity. What exactly is polarity? A polar bond is when there is a difference in electronegativity‚ which means the tendency of an atom to attract a bonding pair of electrons. When two atoms are bonded together and one attracts more electrons‚ this results

Experiment 05 Water Hardness October 8th‚ 2013 The hardness of water was determined using the methods of titration‚ conductivity‚ and pH analysis. The mean and uncertainty of CaCO3 is 134±36.0 ppm. An error that could have potentially happened could be that the equivalence point was not correctly established causing inaccurate data. BACKGROUND: 1In hard water there is a high amount of mineral content present in the water. Most of the mineral content that is present

Paper Assessment of New York Tap Water vs. Deer Park Bottled Water MGMT 650 July 25‚ 2011 Turnitin Score: % Purpose: There have been debates over the years on whether people prefer bottled water over tap water. If you step into an office somewhere in the corner or up against the wall is stacks of large blue containers consisting of water. This debate begins with two sides and often times someone would state that “I never drink tap water” or “Tap water is good for you plus it’s no

Drinking water or potable water is water safe enough to be consumed by humans or used with low risk of immediate or long term harm. In most developed countries‚ the water supplied to households‚ commerce and industry meets drinking water standards‚ even though only a very small proportion is actually consumed or used in food preparation. Typical uses (for other than potable purposes) include toilet flushing‚ washing and landscape irrigation. Chlorination is the process of adding the element chlorine to water as

WATER RESOURCES What are water resources? Water resources are sources of water that are useful or potentially useful to humans. It is important because it is needed for life to exist. Many uses of water include agricultural‚ industrial‚ household‚ recreational and environmental activities. Virtually all of these human uses require fresh water. Only 2.7% of water on the Earth is fresh water‚ and over two thirds of this is frozen in glaciers and polar ice caps‚ leaving only

glaciers and polar ice caps melt. It demonstrated that the variation in density greatly affects salt water. I discovered that the increase in freshwater causes a decrease in density. I made three claims. First‚ the higher the salinity of the water is‚ the denser it will be. This was shown in my data by the fact that‚ with 0mL of fresh water‚ the density was 1.108 g/mL For every milliliter of fresh‚ pure water added‚ the density decreases by 0.015 grams per milliliter. I believe the density responded this
