Make sure that there are no problems with your lab that could affect the results before you turn on the light source‚ for example‚ a broken beaker or light source. 12. Make a table to record your results from the lab with. Make the table 4 columns wide‚ mark the first column with “Time”. Mark the second column with “number of floating chads in beaker #1”. Mark the third column with

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

Introduction In the amylase lab‚ it was being tested if amylase‚ an enzyme found in saliva‚ would be denatured by being put in an acid or high temperatures. This lab is about denaturing amylase. It is tested by exposing it to pH and temperature changes. It is then mixed with Benedict’s solution‚ is a solution that changes color from blue to reddish brown when maltose is present. Amylase breaks starch into maltose‚ so is the amylase isn’t denatured‚ it should change colors. Amylase is an enzyme

Service - Our Responsibility Water and Sewerage Authority (WASA) was established by an Act of Parliament in 1965 to manage the water and sewerage sector of Trinidad and Tobago. An essential component of this mandate is the delivery of a safe‚ reliable and efficient water supply to satisfy the demand of all sectors of the economy. Whilst over the ensuing years there has been a steady increase in demand‚ there has not been the commensurate investment in infrastructure and the identification of alternative

antibiotic and disinfectant sensitivity tests to identify an unknown bacterium. Materials and Methods Microscopic and Macroscopic Observations All samples and observations of the unknown bacterium were taken after 48 hours of incubation at 35° Celsius. Microscopic observations were performed on four different microscope slides. Three of these observations were gram stains and the last observation was of an endospore staining. The unknown bacteria samples for the endospore stain were taken off of

purpose of antimicrobial drugs is either to inhibit virus replication‚ without harming host tissues or to interrupt the cell processes or structures of bacteria‚ fungi‚ and protozoa. This lab has brought great interest to me because this is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar‚ which allows

INTRODUCTION This scientific report is to discuss the results of an experiment being conducted on the effect that antibiotics have on the growth of bacteria. This will be done through the use of microbiology. Microbiology is a science in the department of biology‚ particularly microorganisms. These include; bacterium‚ fungi‚ protozoa‚ algae and viruses. This is an important subject to study as microorganisms can be found everywhere‚ covering all matters of different surfaces even including the human

Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study
