Stalford 9/16/11 Milk‚ Food color‚ and Dish soap Lab Purpose/ Objective: The Purpose of this lab is to find out what happens when food coloring placed in different sorts of milks has dish soap (detergent) added to it. Our objective is to determine what the milk and colors will look like after adding the soap. Hypothesis: After preforming the lab one time through‚ we are able to hypothesize about what could happen when we change different factors within the lab. I hypothesize that the lower content

TFMB1001 24/10/12 Aim of the experiment: Prove that microbes are everywhere Materials required: Agar dishes NA‚ Petri dish S.D.A.(sucrose dextrose)‚ swabs‚ cotton bud‚ labels and marker. Procedure: (A) – Isolate microbes from me (bacteria) 1- We marked‚ divided by 4 and labeled the bottom of our Petri dish. 2- On NA we swabbed areas such as: chicks‚ rings‚ underneath of a watch‚ sink and disinfectant trigger 3-We closed

inoculate the agar dish labeled water with the water sample. Use only enough water to cover the top surface of the dish (approximately 4 drops). 4. Cover the dish and let it sit for 30 minutes to ensure the water soaks into the agar. 5. Incubate the dish upside down at room temperature for 24–72 hours. 6. Observe the dish and count the number and types of colonies. Record the results in Data Table 1: Environmental Colony Formation‚ in the Lab Report Assistant section. 7. Soak the dish in a 10%-bleach

surface has the most germs. I tested ten surfaces and let the petri dishes grow for five days. Over the five days I counted the spores each day and took pictures every other day. It is amazing how things can look and feel clean but they are actually filthy. It is also crazy how many surfaces we touch every day and how one thing we touch can make us sick. Overall‚ I learned many things about growing bacteria. Hypothesis I think the computer lab keyboard will have the most germs. I think that because it

Diversity and Ubiquity of Microbes Pre-Laboratory Questions 1. What environmental settings would you expect to provide rich sources of microbes‚ in terms of overall numbers and different microbial types? Since the most of the microbes are ubiquitous‚ they are readily found in public bathrooms‚ phones‚ countertops‚ door handles‚ kitchen sinks‚ and human body parts such as the face and hands (Sherwood‚ 2017). In addition‚ public places exemplified by hospitals‚ grocery stores‚ and schools present an

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

Lab 1 – Ubiquity of Microbes Bacteria are the most widely distributed organisms in the biosphere. They are found in all different types of soil‚ water and even in the bodies of other living organisms. Every single place that humans have explored on the Earth‚ have shown to contain microbes. Bacteria are living organisms and like all living organisms‚ they require energy and carbon sources in order to metabolize and reproduce. And like all living organisms they respond to changes in their environment

4300/6938 Biomolecules Microbes in Gut Increase Fat Absorption You may think you have dinner all to yourself‚ but you’re actually sharing it with a vast community of microbes waiting within your digestive tract. A new study from a team including Carnegie’s Steve Farber and Juliana Carten reveals that some gut microbes increase the absorption of dietary fats‚ allowing the host organism to extract more calories from the same amount of food. Previous studies showed gut microbes aid in the breakdown

First‚ the students label the petri dishes‚ with the elements Mg‚ Ca‚ and Al. Next‚ the students place the different elements on the top of the petri dishes and then filled the dishes with water. After that‚ they placed each element in the water and put the top on and recorded what happened. Then they opened the dish a put a drop of phenolphthalein on each element and recorded the reaction. The students discovered that sodium and magnesium reacted‚ but aluminum did not. Sodium turned into a gas when

of an unknown microbe by observing its reactions to a barrage of chemical and physical tests. Different microorganisms react in different ways‚ due to their function‚ digestibility‚ morphology‚ chemical make-up and other details. By observing the responses to these tests performed in a particular sequence‚ some can be eliminated as possibilities and others require further investigation. Materials and Methods: A stock culture‚ labelled 25‚ was stored at room temperature (in the lab desk). A transfer
