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

Jennifer Hauss March 4‚ 2015 Bacterial Transformation Lab Report Introduction In this lab‚ the goal was to transform the bacteria e-coli to glow in the dark (or under a black light). Four plates were set up with agar in them for the bacteria to feed on and grow. Changes were then made to the bacteria. One plate was the control plate‚ having only the LB or agar for the bacteria and negative pGLO‚ which is the liquid not containing the plasmid. This is the plate that was compared with the three

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

Introduction Microscopes have brought to light a new realm of information that originally laid dormant and invisible to the naked eye. It has enhanced biology and brought forth great advancements into the study of living organisms. Many discoveries have been achieved through the microscope. One of the major ones is the cell theory that we have talked about in this chapter. Having a microscope enables us to study even the smallest of details in organisms and allows us to conduct research. Another

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

Then pick a slide‚ then select the lowest ocular power (4x) to set microscope into low power. The reposition slide into the circle of light by turning the two knobs located at the right of the microscope. The top knob moves slide back and forth‚ where as‚ the bottom knob positions the slide from side
