Introductory Activity Heart Rate (pulse) Have the students find their heart pulse on the carotid artery of the neck. Use the index and middle finger to measure the pulse. Count the number of beats for 6 seconds and add a zero to the end of that number. This number represents the heart beats per minute. The heart pulse is located on either side of the wind pipe‚ next to the voice box. Allow the students to practice measuring their pulse to determine their resting heart rate. Explain that they need to

Science Coursework-Rates of Reactions Introduction Investigating how the concentration of sodium-thiosulphate (STS) and hydrochloric acid (HCL) affects the rate of reaction in the experiment. In addition I am also checking how different variables affect my experiment and also how I can make my test more precise‚ reliable and accurate. Strategy According to my results‚ as the concentration of STS solution increased the rate of reaction of my experiment was increased. Also as the concentration

Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction. This is a well informed

Exchange rate development in Ethiopia Monetary Development The legal tender currency of Ethiopia was issued on 23 July 1945 by defining the monetary unit as the Ethiopia dollar (E$) with a value of 5.52 grains (equivalent to 0.355745 grams) of fine gold. The linkage with fine gold was in accord with the monetary system established by the Bretton Woods Agreement of 1944. For the five years following the proclamation of the national currency (1945–1950)‚ money supply of the country was determined
