The experiment began using a TI-84 calculator as a random number generator‚ and 1-4 inputted into the calculator to determine order. Numbers 1-3 were inputted to determine the order of experimental groups for the participant. A plastic tub was then filled with a liter of water at 25℃‚ and a thermometer was placed into the water to verify. The

Water Rockets Abstract Water rockets have been a source of entertainment and education for many years. They are usually made with an empty 2-litre PET bottle by adding water and pressurizing it with air for launching. Water rockets are used to help students understand the principle of aeronautics. Aim The aim was to design and perform an experiment to determine the volume of water to use in order to obtain maximum height for the bottle rocket. Introduction Bottle rockets are often used in

The turbidity was taken with a Turbidity sensor and a Secchi disk icon. A bottle of water was inserted into the turbidity sensor‚ where light was refracted through it. This picked up on the cloudiness and the debris in the water. The disk icon tested the water by adhering the sticker to the bottom of a jar and filling the jar with water. The appearance of the disc would change to show the turbidity levels in the water. The temperature was measured using a thermometer. Lastly‚ the Flow Rate was calculated

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...

Carbon oxide and Nitrogen oxide are one of the many air pollutants this world is having problems with. As for carbon oxide and nitrogen oxide they fall into the category of a primary pollutant‚ or as so I believe. The reason for why I believe this is because when nitrogen oxide is let out and exposed into the air it can harm the growth of our plants and crops which results us to lose quantities of our food being grown. Also if nitrogen oxide is inhaled it can cause health complications such as asthma

Water has polarity. Polarity is the uneven distribution of charge. Water has cohesion‚ adhesion‚ and heat capacity. Cohesion is the attraction between molecules of the same substances. Adhesion is the force of attraction between molecules of a different substances. Heat capacity is the amount of heat it takes to raise temperature of a substance. The experiment displayed shows water can have adhesion and cohesion. The hypothesis of this experiment is if a nonpolar substance is added to water

In this experiment I will investigate the temperature of 50cm³ of water before and after I have added calcium chloride‚ I will gradually increase the amount of calcium chloride by 1 gram to see if there is a significant change. When Calcium Chloride is mixed with water it performs an exothermic reaction which makes new bonds between the salt (Calcium Chloride) and the water. This will therefore make the solution of the reaction increase in temperature. Exothermic reactions transfer energy

information can be classified as guided or unguided. Guided media provide a physical path along which the signals are propagated; these include twisted pair‚ coaxial cable‚ and optical fiber. Unguided media employ an antenna for transmitting through air‚ vacuum‚ or water. • Traditionally‚ twisted pair has been the workhorse for communications of all sorts. Higher data rates over longer distances can be achieved with coaxial cable‚ and so coaxial cable has often been used for high-speed local area network and
