	Fun Science Project - Which Drinks Raise Blood Pressure? It is generally understood that coffee, tea and soft drinks will elevate your blood pressure, and that elevated pressure could lead to a heart attack or a stroke. Caffeine is the most widely used drug in the world. It has been known to produce undesirable side effects such as nervousness, insomnia, irregular heart beat, high blood sugar and cholesterol levels, excess stomach acids and heartburn. Caffeine stimulates the central nervous system and can cause mild alertness, heightened anxiety and body tension. It can be habit forming. It depends on how you take it and how much you take. Age and size have a lot to do with it. A caffeinated soft drink consumed by a small child can have the same effect as four cups of coffee consumed by an adult. It can produce trembling, nervousness, chronic muscle tension, irritability, throbbing headaches, disorientation, depression and insomnia. Use of caffeine combined with smoking can be a double threat. Nicotine also raises blood pressure. The use of caffeine and nicotine can be harmful to your health. Here is an experiment that you can conduct to see for yourself. It could be a great science fair project, or you might do it just for your own edification. You should recruit a number of subjects of different age and gender. The more the merrier. Twenty subjects more or less; it's up to you. You will need lots of soda, either Coke or Mountain Dew, or Pepsi, or any soft drink with caffeine. You will need coffee, lots of it. Make sure you do not use decaffeinated coffee. You will require a timer. An easy-to-use blood pressure monitor is required. You must learn how to use it properly. If you are testing children under age 21, you should get their parents' permission in writing. You should get assistance in the proper use of a blood pressure monitor. It is not difficult to get proper readings once you learn the technique. Test half of the subjects with soft drinks like Coke or Mountain Dew. Each contains about 80 mg of caffeine. Test the other half with coffee. Each cup contains about 80 to 160 mg of caffeine. You must first test the subject's blood pressure before consuming any of the drinks. Keep careful charts, make precise notes. Check each subject's blood pressure again, after they have consumed the caffeinated drinks, thirty minutes later, and again 60 minutes later. Blood pressure readings can often vary from reading to reading. What have you learned? Did the blood pressure readings go up?

It can be identify as the exit of sciences into the nanoscale, or utilizing the science into modern ways, the movements of nanotechnologies approach from rehabilitated awareness in science. Nanotechnologies has two major approaches equipment and procedure which make themselves from molecular components, and to accumulate chemically by distinguishing molecular values. The study of the materials used in formation of nanotechnologies is known as a nanomaterials. The distinctive possessions of nonmaterial formation on the nanometer scale has flicker the awareness of resources. The manufacturing of materials through its products such as plastics filler, coating, and protection from the sun rays in cosmetics, moreover the expertise seize to undertake more for the prospect to both product and on markets. Nanotechnologies play an important role in almost every industry some of them include medicines, electronics, plastics, etc. it is simple that make in allowance of advance in various purpose. The science and engineering departments traces back to the pasts of 1864, the governments affords an occasion for the educational students to research the materials, further the achievements is based on the advances in the science and technologies allowing the new developments in technologies and achieves the progress into research field with its relationship through industry.
