In order to write a good research paper, you need to come up with a strong research question. This question will guide your research and help you stay on track as you write your paper. In this article, I’ll reveal the key elements of a good research question using the acronym FIRST (feasible, interesting, relevant, […]
Objective To determine if the type of sugar used in yeast fermentation affects fermentation rate. Background Yeast (Saccharomyces cerevisiae) is a single-celled microorganism used in the production of bread and alcoholic beverages. It is a facultative anaerobe that ferments sugars to make carbon dioxide and ethanol. Facultative means that it can grow whether oxygen […]
Objective To compare physical properties (mass, volume, and length) of bean market classes. Introduction In this lab you will learn how to collect scientific data and how to organize and present them so that they can be easily understood and interpreted. You will be given market classes of beans to compare their mass, volume, and […]
The scientific method encourages independent and objective thought through a gathering and analysis of evidence. Hopefully as you take food or related science classes you will develop the skill to reason objectively. I wrote about the scientific method in another article but thought I would speak generally here on objective reasoning. The difference between objective […]
As a science student, you will undoubtedly spend a lot of time in the laboratory. It is essential that you understand and follow all the safety rules in order to protect yourself and those around you. In this article, we will go over essential safety rules that you should always keep in mind when working […]
