My Science Project Can water float on water? My Prediction I predict that water can’t float on top of water. Simply because it sounds impossible‚ but it will be interesting to find out if however it is possible. The Experiment First‚ I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

Water Pollution Water pollution is the contamination of bodies of water such as ponds‚ lakes‚ oceans‚ rivers and even groundwater. Water pollution is mainly caused by many human activities‚ which can be harmful to animals and plants which live in these bodies of water are located. Nature also takes its toll on water pollution such as volcanoes‚ severe storms‚ and earthquakes also cause major changes in the quality of water. Water is typically considered to be polluted when it’s impaired

An Introduction to Water Analysis February 1 and February 8 2011 Aim and Objective: The aim of this experiment was to determine the pH level of an unknown HCl solution. While doing so‚ we would also be receiving a good and fundamental understanding of how to use modern lab equipment to determine the chemical and physical properties of water bodies. Method: Make sure safety gear is always on and equipment is always clean. Part 1- Direct Analysis by pH Test Kit We grab a 50ml beaker

Alcohol Lab Data Conclusion Objective: The objective of this lab was to find the concentration of an unknown alcohol solution. Procedure and Data: We found the masses of 10.00 mL of each of the known concentrations of alcohol (minus the beaker mass) by placing the beaker onto the scale‚ zeroing the scale‚ and then pouring alcohol into the beaker‚ repeating for each different concentration solution. Then‚ using the same method‚ we found the mass of 10.00 mL of the unknown concentration. We recorded

Introduction Pollution can be defined as a harm to the environment which can cause a lot of bad consequences to human health‚ living resources and ecological. Thus‚ pollutants can be gain from many sources and can take many forms. The pollutants can contaminate land‚ water or air. In order to identify types

English 3 Research Paper Water Pollution: A Global Problem In 2009‚ the International Coastal Cleanup (ICC) collected 3.4 million kg of marine debris worldwide; 10.2 million individual pieces of rubbish in 108 countries. Water pollution is everywhere and is a continuing problem caused by our careless behavior‚ which needs to be stopped. It is affecting people as well as animals all around the world. First‚ water pollution causes many problems all over the world that effect marine life as

Water is the basic requirement for living beings. About one sixth of the world population has no access to safe drinking water. Even though two third of earth’s surface is covered with water‚ fresh water sources accounts less than 2.5%. Out of this‚ only a small fraction of water is easily available for access to humans as the remaining is locked in glaciers and deep underground aquifers. Rising population and improved standard of living have escalated per capita demand for fresh water. India had
