Kathryn Marchessault Physics Lab LR Tuesday 8-9:55 Due 02/26/15 Experiment #1 Free Fall Experiment Abstract In this experiment we studied the motion of an object in free fall‚ that is an object being dropped from a certain height to Earth’s surface. In this experiment we tested the idea that no matter what the size‚ shape‚ color‚ etc. of the object if it would still experience the same constant acceleration throughout its fall (short distance). The constant downward acceleration it experiences

Date of Experiment: 6/9/15 Report Submitted: June 10‚ 2015 Title: Observations of Chemical and Physical Changes Purpose: the purpose of this lab experiment is that I will be able to decipher the difference between a chemical and physical change. I will be about to tell whether a chemical change has occurred during the experiment or if it was a physical change and I will be able to answer why it is either one. Procedure: In the lab experiment‚ I mixed different types of chemicals

1.If the inclination angle is zero‚ how does the path of the Sun in the sky change as the planet moves from the right side of its orbit to the left? What is the longest duration (in hours) of sunlit time during the year? What is the shortest duration of sunlit time? How does the angle of sunlight striking the ground change? What is the change in average temperature? The path of the Sun in the sky doesn’t change as the planet moves from the right side of its orbit to the left. The longest

Experiment 12: Calorimetry and Hess’s Law Purpose: The purpose of this lab is to determine the enthalpy of reaction for the burning of one mole of magnesium in oxygen. Although the reaction is exothermic‚ the ∆HRXN will be determined by using calorimetry and then using Hess’s Law to manipulate the data collected to yield the answer needed. Procedures: Dillon‚ Stephanie. “ Calorimetry and Hess’s Law.” Laboratory Manual. Pearson Publishing‚ 2012‚ pp.168-177. Data and Results Part A

In Graph 1‚ each line of color represents a different level of pH added to the solution. When pH 9 was added‚ it produced the highest rate of reaction (the most oxygen was produced)‚ whereas when the more acidic pH 5 was added‚ the rate of reaction was much slower‚ and less efficient. The higher the oxygen evolved (gas produced)‚ the more reactions were being produced/higher rate of reaction. Different types of enzymes’ reaction proportions differ based on the pH being added. For example‚ intestinal

Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2‚ 2014 I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic

LIM THOY XIAN (THENESA) WS1 Student ID: 11044641 DESCRIBE In this week seminar‚ we formed a team of 4 to 5 based on a range of criteria by doing the team roles and attributes test. Every group is distributed with a balance student’s criteria on different team roles like leader‚ doer‚ achiever‚ thinker and carer. With the highest score in thinker attributes among the 5 roles‚ I had assigned to a team of 4 acts as a thinker role. Then‚ a discussion was carried out within team members
