Enzyme Lab Daniyal Abdali (Rachel Lee) (Sarina Dolch) SBI 3UI Mr. Vrabec October 20‚ 2009 Test #1 * Add a small piece of cracker in test tube #1 and add Lugol’s solution. Observation #1 * The cracker turned a black colour when the Lugol’s solution was added to it. This was a positive result‚ meaning that the cracker contains starch. Test #2 * Add a bigger piece of cracker in test tube #2‚ add 5 mL of Benedict’s solution‚ place in a boiling water bath‚ and record observations

Chapter 1 INTRODUCTION Rationale Over the decades ago‚ Seymour Papert (1980) wrote Mindstorms and advocated a revolutionary philosophy in which technology was as seen as a fulfilling two major roles in education: (a) a heuristic role in which the presence of the computer was seen as a catalyst of emerging ideas and (b) an instrumental role in which the presence of the computer would carry ideas into a world larger than the research centres where they were incubated. When the Children’s Machine

When given two equations the goal is to make the equations equivalent to one another. These two equations are equivalent. Two equations are known to be equivalent if they have the same solution set. A solution set is a set of numbers that that solve an algebraic equation. In the first equation‚ the solution set is {5}. In the second solution set both sides of the equation must be equal. Equal means that both sides are balanced. The equality of addition property states that each side of the

Unit 5. Lab. New Building-Wired and Wireless If I choose to design the new building with a wired network the main benefit is there would be a low chance on interception. Choosing a wired network will also have a lower risk of security issues; reliability and speed are primary benefits as well when using physical connections in a wired network. The basis of the new building will relay on loads of data to be moveable that is why a wired network allows the control. Wired LANs provide superior performance

At a young age‚ students are introduced to the threat that has served as motivation or the down of many careers or lives‚ known as stereotypes. Stereotypes are defined as a broad introduction for students into their own choices in life. Some may argue that these stereotypes can serve as a pupil’s hamartia‚ but can also encourage students to strive for success. When students feel threatened upon being categorized‚ their social and educational performance can be dramatically affected negatively or

Simple Harmonic Motion Objective The purpose of this experiment was to investigate the different variables describing simple harmonic motion (SHM) using a spring-mass system in vertical oscillation. We measured the position and velocity of the spring-mass system under different conditions in order to extract parameters used to describe SHM such as amplitude‚ frequency‚ and phase. We tested whether the predicted behaviour based on our mathematical model of SHM was cohesive with the observed parameters
