Introduction: This report will talk about the experiment that was conducted to see what percent of hydrogen peroxide had the greatest reaction with the potato cube. The enzyme in this experiment was catalase, which could be found inside of the potato cube. The substrate was the hydrogen peroxide. The role of the potato cube was to react with the hydrogen peroxide causing it to break down at a quicker rate which released oxygen (O₂). Three factors that could influence the enzyme’s activity is the

This lab explored techniques in steam-distillation to extract clove oil from ground cloves. In the second part of the experiment, designed by the students, eugenol was isolated from clove oil via chemically active extraction, using acid-base chemistry. This isolated compound was analyzed via Infrared Spectroscopy and Gas Chromatography. Eugenol, eugenol acetate and caryophyllene (Figure 1) were isolated from ground cloves via steam distillation. To do this, 5.04g of ground cloves were added to a

Introduction: Small, calcified, hard, whitish structures are called human teeth which are located in the mouth. A tooth which is divided into two basic parts the crown and the root. The crown is the whitish part of the tooth, which is visible while the root is not. Teeth are made up of four kinds of tissues: Enamel, Dentin, Cementum, and Pulp. Enamel, which contains phosphorus and calcium protects the tooth from decay. Under the Enamel is the tissue Dentin, it is not as hard as Enamel so the

Catechol oxidase is an interesting compound to work with, because of this chemical fruits and vegetables turn brown when dropped or cut. I will know how catechol oxidase performs under different pH levels using a spectrophotometer to record its absorbance. This will give the information to determine if more or less product is being made. After performing the test and understanding the results I will compare the difference between absorbance, and if any problems occurred during the process. Introduction

A total of 5 weeks is what it took for a group of 8th graders to figure out what was in a mystery mixture that their teacher gave them. They looked at the physical properties, such as color, smell, size, and shape. They also looked at chemical properties such as fizz, bubbles, and the odor of different substances and the mixture to compare and contrast. The 8th graders combined different substances and added water. They took the temp, timed the reactions, and argued about their ideas until they came

the exposure time, the longer the rods. Some of the pictures taken are inconsistent with this trend because some of the cells are smaller as exposure time increases, while some are larger when exposure time increases. After observing the cells during lab, it appeared that some of the cells lost some of their motility as exposure time increased. Serial dilutions (ranging from 100-10-5) was then performed to make it easier to find mutations in the Lac genes before plating it on MAC plates. MAC plates

reliable. I wish to study the black body and wild type traits of the body color characteristic. The phenotype of the black body fly would be having a black body color. The phenotype of a wild type fly would be having a orange body color. During this lab, my goal is to discover which of the two traits is dominant to the other. My hypothesis is as follows: If the wild type trait is dominant, then a cross between a wild type phenotype parent and a black type phenotype parent will result in an F1 distribution

Title: Wet mount Aim: The aim of this experiment is to make a wet mount side and observe the paramecium’s and other microorganisms found in the pond water. Background information/ introduction A technique that is widely used in science biology is wet mounts. Practising this technique helps in order to study slides with specimen under a microscope. In this skill the specimen ejected along with a drop of liquid (e.g. water) and then it is covered with a cover slip. Unlike permanent mount slides

The average hemolysis time for Thiourea and Triethylene Glycol appeared to be the highest out of all eight of the molecules with Triethylene Glycol at the top (figure 1). Diethylene Glycol and Ethylene Glycol came as the third and fourth highest (figure 1). Urea was the fifth highest in hemolysis time (figure 1). Lastly, Methanol, Ethanol, and Propanol, with their similar heights, had the shortest hemolysis time (figure 1). Referring to the conventional criteria, the difference between the average

To find the most effective exercise modality for patients with Ankylosing Spondylitis (AS). By Janice Lloyd, September 2016. Introduction Ankylosing Spondylitis (AS) is an inflammatory autoimmune Arthritis which is usually diagnosed from early teens to fifty years of age. Although 8% of the population has the Gene HLA-B27, they do not have AS, however, 9 out of 10 people with AS have the Gene. Recently two more Gene's were found that have been associated with AS, IL23R & ARTS1. AS is diagnosed
