that profoundly stuck out to me the most was the “water tank‚” lab. The procedure of the lab was to shoot a red laser beam into the tank of water from three different directions. I first shot the laser from above the water surface‚ then from below‚ and finally from the side of the tank. Interestingly enough‚ each direction‚ the laser would bend in the water. The fascinating part of this lab was the idea as to why the laser could not exit the water tank‚ and instead would bend equally in each direction

Materials: 1. 2 Plastic cups 2. Tap Water 3. Teaspoon 4. Bag of salt 5. Freezer 6. Clock 7. Paper 8. Pencil Procedures: 1. Take plastic cup and pour in one cup water in each 2. Take one teaspoon of salt and mix it in one of cups 3. Put both cups in the freezer 4. Observe. Conclusion: When salt is added to water it slows the freezing process down‚ therefore the freezing point of tap water is higher than the freezing point of salt water. Hypothesis: If... ‚ then...

World Water Day 3/22/2011 10 Ways to Save Water in the Home: 1. Keep a pitcher of water in the refrigerator instead of running the tap for cold drinks. This way‚ every drop goes down you and not the drain. 2. If you shorten your shower by a minute or two‚ you’ll save up to 150 gallons per month. 3. Designate one glass to use for your drinking water each day or refill a water bottle. This will cut down on the number of glasses to wash. 4. Soak pots and pans instead of letting the water run while

1 Forms of Water 2 • Water consists of an Water is a Polar Molecule oxygen atom bound to -has oppositely charged two hydrogen atoms ends by two single covalent bonds. – Oxygen has unpaired & paired electrons which gives it a slightly negative charge while Hydrogen has no unpaired electrons and shares all others with Oxygen – Leaves molecule with positively and negative charged 3 ends Water molecules form Hydrogen bonds slightly positive charge hydrogen

properties of water were tested and proved. These trials and experiments were able to verify the adhesion‚ cohesion‚ polarity‚ temperature stabilization‚ solvency‚ and density changes exhibited by water. During the glass and wax paper lab‚ we observed the adhesive properties of water. When a droplet of water touched the glass‚ it dispersed immediately. The droplet placed on the wax paper remained intact and in droplet form. Also‚ when the glass and wax sheets were flipped‚ the water remained on

not exist without water. Seventy-five % of the Earth is covered in water providing an environment for organisms to live in. the water molecule is made up of two hydrogen atoms and one oxygen atom. As oxygen atoms are more electronegative that hydrogen atoms the electrons shared covalently between the oxygen and the hydrogen atoms tend to spend more time near the oxygen atom making it partially negative and making the hydrogen atoms partially positive. The partial charges in the water molecule allow

A Survey has been conducted to find out the possibility of tapping water from Dzüna Rivers and has been found to be feasible. This Project envisages for a 975 million litre capacity Balancing Reservoir to store the surplus monsoon run-off water from Dzüna river. This will‚ to a large extent supplement the deficiency during lean season

The water cycle is one of the most or the most important cycle that we have on planet earth. Earth is able to support life because of the plentiful water that it contains. When astronomers search for planets outside of our solar system to see if there is a chance for life on other planets‚ the first thing that they look for is if the planet contains water. However‚ humans are starting to affect the way that the water cycle happens by‚ “We take water out of the system to irrigate crops…” (creditvalley
