Middleton World Area Studies September 20‚ 2013 The Effects That Water Scarcity Has On Education You wake up at seven thirty‚ you’re hungry‚ your stomach hurts‚ and your feet hurt. But you have to get up anyways. You have to go get your families water‚ but its contaminated water‚ you could get sick from this and your family could get sick‚ you miss school because you are the oldest in the family and it’s your responsibility but it’s the only water source where you live. Many children in Kenya are

Aim To investigate the effects of increasing salinity on potato cell mass. Background Information This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a region with low concentration. This movement must take place across a partially permeable membrane such as a cell wall‚ which lets smaller molecules such as water through but does not allow bigger molecules to pass through. This process will take place until

Let’s Make Salt Purpose: Could NaCl be made using NaHCO3‚ hydrochloric acid‚ and a boiling chip? Hypothesis: If I combined NaHCO3‚ hydrochloric acid‚ and a boiling chip I think it will form NaCl because when you balance the equation it makes a new chemical reaction. Materials needed: test tube cleaner‚ test tube‚ test tube tongs‚ hot plate‚ a scale‚ graduated cylinder‚ water‚ goggles‚ fire retardant glove‚ beaker‚ test tube holder‚ a scoopula‚ hydrochloric acid‚ sodium bicarbonate‚ soap‚ pipette

Each year‚ on average‚ there are 105 snowstorms. Salt is driven around in millions of trucks across the country to help deice the roads to make way for safe travels. In the United States‚ 20 billion pounds of salt are used every year to treat the icy roads after snowstorms. Common salt‚ the salt almost every American has on their dinner table‚ NaCl is most frequently used to deice roads across the country. Salt is very cost effective and efficient when used properly‚ however it is causing more harm

Science IA Rough Draft The Effect of Temperature on The Activity of The Enzyme Catalase Introductions: Enzmyes are proteins that catalyze chemical reactions. All living things have catalase present in them. Catalase is a common HYPERLINK "http://en.wikipedia.org/wiki/Enzyme" enzyme found in nearly all living organisms that are exposed to oxygen‚ where it HYPERLINK "http://en.wikipedia.org/wiki/Catalyst" catalyzes the decomposition of HYPERLINK "http://en.wikipedia.org/wiki/Hydrogen_peroxide"

Let us take a look at some typical types of boilers. Firetube boilers Firetube boilers consist of a series of straight tubes that are housed inside a water-filled outer shell. The tubes are arranged so that hot combustion gases flow through the tubes. As the hot gases flow through the tubes‚ they heat the water surrounding the tubes. The water is confined by the outer shell of boiler. To avoid the need for a thick outer shell firetube boilers are used for lower pressure applications. Generally

The absorbance value(y) read from cuvette containing starch‚ water and α-amylase at the respective temperature or pH represents the amount of starch-iodine complex which is left after the enzyme has hydrolyzed the starch.In order to get the amount of product;P (maltose and glucose)

Record the ammeter reading as the temperature increases 10°C before disconnecting the wire from the circuit and measuring the wire resistance immediately using the ohm meter. 4. Repeat procedure 4 when the temperature of the wire increases every 10°C until the highest temperature is reached and the measurements are recorded. Conclusion The hypothesis that when the temperature of a wire
