Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Clocky Invented by Gauri Nanda‚ for an industrial design class‚ then a graduate student at MIT Media Lab‚ Clocky won the 2005 Ig Nobel Prize in Economics. Clocky is a brand of alarm clock with wheels‚ allowing it to move around in order to force you to awake in an attempt to find it. After earning her Masters Degree from MIT‚Gauri Nanda founded a company‚ Nanda Home‚ to commercialize this product Cloky‚ and other home products. The market for watches and clocks was bigger than $7 billion in the

On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase is an enzyme found in food such

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded

Nicholas Negroponte‚ founder and director of the MIT Media Lab‚ introduced the idea for the $ 100 laptop in 2005. The laptop will be directed towards the child in "developing countries." The intent is to help education in those countries. The purpose of this project‚ to be specific‚ is "To provide children around

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

Scott Eaton The artist of this paper ’s five pieces of work are created and conceptualized by Scott Eaton. He is an artist and designer from the UK and uses traditional art techniques with digital tools. What makes his work so fascinating is his knowledge of anatomy and clean use and mastery of the media. This piece is gorgeous and for it being a digital sculpt‚ you could hardly tell. The texturing is almost like real clay mimicking skin! It is to be acknowledged that this piece was created

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

In 21st century that we live in‚ communication can be done in many different ways other than conventional speaking right in front of each other. The reason for that is because of the existence of communication technology and the wide interest in this technology from people around the world. Communication technology is improving as we speak and more important sector is depending on it to gain benefits such as business and politics. Communication technology includes telephone‚ radio‚ television

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress
