of Alcohol vs. Caffeine on Water Flea ’s Heart Rate. Title Page Abstract For our most recent experiment we tested the effects of immersing water fleas in caffeine and alcohol to see the effects on their heart rate. Before the experiment we hypothesized that if you place the water fleas in alcohol then their heart rate will slow down‚ and if you place them in caffeine then their heart rate will raise. For this experiment we needed water fleas‚ tap water‚ two pipettes‚ a microscope

Water and Fire Water and fire are two of the “classical elements” as said by the ancient Greeks. In regard to today’s society‚ science has found this to be myth and quite a humorous joke. Yes saying that it is an element when regarding Chemistry and when saying it makes up humans‚ is ridiculous. When looking at it from a different perspective than I’d have to agree with the ancient Greeks. When they say “classical elements” it is saying that these are two things that are major components of life

The tests that were used were that of: A faecal coliforms test‚ phosphate test‚ nitrates test‚ pH test‚ dissolved oxygen test and a total dissolved solids test. It was thought out that filtered water would hold the highest standards‚ the most sanitary water samples was that of tap water‚ then followed by filtered‚ then tank (rain) water and creek water respectively.

fresh water is also becoming a scarcity. The limited availability of fresh water and its unequal distribution make water pollution a matter of great concern. Water pollution is generally localized and confined‚ making it more severe. The pollutants undergo many reactions and can become hazardous. 70 % of India’s fresh water is polluted‚ including several high altitude lakes. While water pollution is easier to study and manage‚ its control is highly complex and very costly. Water pollution

Hard Water How can water be hard? Well‚ it can‚ but maybe not in the sense that one would think. Hard water refers to water with dissolved calcium and magnesium ions in it. Rainwater is naturally soft‚ but when the water runs through the ground or over rocks causing erosion‚ calcium and magnesium ions can be easily picked up. Most people prefer hard water to soft water for drinking‚ because the ions are good for you‚ and because soft water leaves a “dry” taste in one’s mouth (1‚2). Big businesses

Does Soap Affect the Surface Tension of Water? Background: Surface tension refers to water’s ability to "stick to itself". Surface tensioncan be measured and observed by dropping water (drop by drop) onto a penny. Thenumber of water drops that can fit on a penny will surprise you. Question: How does soap affect the water’s surface tension? Hypothesis: I think that the surface tension of soapy water will be less than that of freshwater because H 2 0 has strong polar bonds‚ and when water is mixed with
