History[ edit ] An exterior view of the college, Pomona College was established as a coeducational institution on October 14,by a group of Congregationalists. The founders' goal was to create a college in the same mold as small New England institutions. The college was originally located in Pomona, California ; classes first began in a rental house on September 12,
This allows students to focus on the process and techniques of investigation and the subsequent reporting. However, in Year 12 students are often given freedom to choose a topic or research question from the work covered over the whole of the course.
These "Open Inquiry" EEIs may provide more ownership, engagement and deeper understanding for the students but do place a bigger demand on resources and laboratory management.
However, many teachers have found strategies to manage this should they choose to opt for a Open EEIs. A Materials Requisition Form accompanies this document. My thanks to Biology teachers from Nanango for sharing this.
Examples of Risk Assessment forms can be found in the tasks available on this page. A comprehensive form developed over several years by Urangan SHS can be found here: It is only an example and should not be assumed to necessarily meet the legal and safety obligations of any particular school or situation.
The method of artificial variation: The method of concomitant variation: This is also called a "correlation method". You can think that nature has manipulated the variables but it is still appropriate to class one as dependent and one as independent.
For example, do young leaves have the same density and distribution of stomata as older leaves; or how does temperature IV in a natural environment affect stoma opening DV? In this second case you do not need you to control the environmental temperature, but you do need to measure the DV at different temperatures.
The difficulty with the second approach is the control of other potentially influential variables such as humidity - as you have to take what you get. However, that does not preclude the variables in relationship being considered the IV and DV or being graphed as such.
One way to address the confounding variables eg humidity is to collect data on the other variable as well.
You can run the statistics on each pair separately, but, for students who are not that "stats-savvy" then they could look for interactions between them at a visual level. Although some micro-organisms are deliberately used to make foods such as yoghurt and cheese, other microbes 'spoil' food.
Food, as well as meeting the nutritional requirements of humans, will also meet the nutritional needs of a vast range of micro-organisms. These microbes will multiply rapidly in food, given the appropriate conditions such as temperature, pH and moisture.
The flavour, aroma and texture will ultimately be affected. Those most affected by food poisoning are the elderly, the young and immune suppressed individuals. A petri dish culture of the yeastlike organism fungus Candida krusei, after 10 days growth on dextrose agar.
This species is known to be a food spoilage organism. Dichloran Rose Bengal Chloramphenicol Agar is a commercially specialist culture medium for viable yeasts and moulds in food products.
It incorporates Rose Bengal, which both helps limit colony size and is selective against bacteria. Effects of different anti microbials on bacterial growth Joseph Lister first introduced aseptic surgery in when he used a spray of carbolic acid phenol C6H5OH as a germicide.
Since then the control of growth by antimicrobial compounds has grown into a multi-billion dollar industry.
A good EEI is to assess the effect of a variety of antimicrobial disinfectants on bacterial growth. Our labbies prepare the plates and order in E. Students then put a 'wash' of E. Small paper discs like out of a hole punch are sterilised and then soaked into different anti-microbials.
The discs are placed onto the agar plates and then into the incubator for a couple of days. If the anti bacterial is effective there is a clear ring around the disc where the E. Students have used the width of this ring to indicate effectiveness and to collect quantitative data. The experiment can work quite well; keen students have then researched the active compounds within the antibiotic, how they act upon the bacteria and link to the results observed".
No single disinfectant is ideal.A thesis statement should be provided early in your paper – in the introduction part, or in the second paragraph, if your paper is longer. It is impossible to create a thesis statement immediately when you have just started fulfilling your assignment.
Biology offers a research-focused Master's degree, which we call the thesis MS or Plan A MS. This program is designed for students who want to gain research experience but are not ready for or are not yet committed to the extended level of research required for a Ph.D.
Biology takes relatively few thesis M.S. students into the program, but under special circumstances will do so.

A thesis for Distinction in Biology should be a presentation, written primarily for the non-specialist reader, of the significance, results and conclusions of a productive research project.
The First Year. Upon arriving at Texas A&M, we help you get acclimated to life in College Station and in the Department of Biology. You will meet your fellow entering students, who will undoubtedly be a source of friendship and moral support during graduate school and beyond.
