The Effects Different Types of Water Have on Plant Growth Abstract This experiment examines the rate of plant growth when watered with different solutions. Throughout the course of a nine week period‚ five lima bean seeds were watered with five different solutions to see which will most enhance the growth of plants. The five solutions consisted of distilled‚ filtered

Over the centuries‚ immigration has benefited the United States for the use of slavery‚ but what about for the economy or just the country itself? The US has been given the name‚ “The Boiling Pot‚” because we have a lot of different races combined into one country. Have you ever wondered how the boiling pot could’ve just been some scrap metal if immigrants hadn’t come into the United States and built it a little? Some people think that immigrants just want to steal our jobs‚ but do they really? Maybe

Salt Case Study Salt and Food We all need a little salt because it helps keep your body fluids at the right concentration. However‚ the majority of us eat more salt than we need. On average‚ people in the UK eat about 8.1g of salt a day. Even though it doesn’t sound like a lot‚ to reduce the risk of disease‚ adults should not be eating more than 6g of salt per day. A main source of salt is table salt. Your body only needs 1/4 teaspoon of salt every day. Salt is naturally found in foods but

The Effects Sodium Chloride has on pond water Introduction Ponds are depressions in the ground that fill with water from either run offs or melting snow or rain fall from many different weather changes. There are two types of ponds permanent and temporary. Ponds tend to be much smaller in size and are usually only six to ten feet in depth. This differs from a lake because the size of a lake is much larger and is much deeper. The temperature of a pond is usually the same from top to bottom and

1.Explain how human interference in the water cycle can affect water availability The water cycle is the process of evaporation‚ condensation and precipitation of water on Earth including rain water and how it is distributed. Human factors such as forest clearing‚ urban construction and changes in land use can all affect the distribution of water. Infiltration can be affected by forest clearance. This also affects percolation and the water table. When there is rain the forests holds a lot of rainfall

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

purpose of the experiment is to determine the effect of cross-linking has on the viscosity of the polymer solution. In the experiment‚ a hotplate was used to heat 50 mL of tap water in a 200 mL beaker to boiling. It took nearly two hours to fully dissolve 2 grams of PVA [poly(vinyl alcohol)] in the water by sprinkling minor amounts bit by bit. 10 drops of 0.1% methyl red indicator was added to PVA solution for the cross-linking part. 0.4 grams of borax was dissolved into 10 mL of hot water. 3.0 mL of
