trials. A clinical trial was established that used blue light therapy to delay and kill the growth of staph infection. Coincidentally‚ blue light therapy is extremely similar to UV light‚ so that inspired this project. The materials used were glass petri dishes‚ an autoclave‚ Staphylococcus epidermidis‚ tanning lights‚ black light‚ sunlight‚ agar‚ and an incubator. To

I: Abstract Observing the effects of ammonium nitrate has on the germination days of C-Fern gametophytes by constructing an experiment with two spore-sown petri dishes‚ one control and one treatment – a normal nutrient-rich agar petri dish and an ammonium nitrate-containing petri dish respectively. The two petri dishes were each inoculated with three drops of spore suspension by a pipet‚ then spores were spread by a sterilized-bent paper clip to allow even distribution of spores.

in This Experiment Haley Wall 10-20-13 Period E Abstract The purpose of the Sow bug lab was to determine if the Sow bugs had a preference of leaves to eat. A brief description of the procedure is that the leaves were put in a Petri dish full of sand and sow bugs. Then there were recordings of how much of each leaf the Sow bugs had eaten each day. Observations on what the Sow bugs had eaten‚ and how they were acting were recorded everyday. The Sow bugs preferred the Hickory leaf

TM How Does Temperature Affect Daphnia Heart Rate? Student Study Guide DID YOU KNOW? The body temperature of the Arctic squirrel drops from 98.6°F to 26.4°F‚ which is below the freezing point of water and is the lowest known body temperature of any living mammal. DID YOU KNOW? The average body temperature of the following warmblooded animals are: Humans: 98.6°F Rabbit: 101.3°F Polar bear: 99.1°F Blue whale: 95.9°F Owl: 104.4°F Ostrich: 102.6°F BACKGROUND Every animal

The chromatography paper was then stapled to form a cylinder. The paper was placed next to the petri dish to make sure that the water level was below the line that was drawn. The paper was then placed in the petri dish making sure not to touch the sides. It was allowed to sit in the salt water for a few minutes until the solvent stopped traveling

Carbohydrate when heated results to a complex group of reactions in absence of nitrogen containing compounds. Such reaction is commonly known as caramelization. Sugars will show caramelization to a relatively high temperature. The browning of these carbohydrates is further facilitated by the presence of small amount of acid‚ salts of this acids‚ phosphates and metallic ions. Lack of moisture in the sugar molecule with formation of anhydro rings are actually caused by thermolysis. When double bonds

Abstract: This experiment was completed with the intention of testing if two specific plants were allelopathic. Allelopathicity is defined as “They are allelon which means "of each other"‚ and pathos which means "to suffer". Allelopathy refers to the chemical inhibition of one species by another. The "inhibitory" chemical is released into the environment where it affects the development and growth of neighboring plants.” (Ref 1) Introduction: Have you ever wondered why certain plants do

INVESTIGATING THE ECOLOGICAL NICHE OF THE CRAB USING A FAIR TEST INTRODUCTION: The ecological niche of the crab Hemigrapsus edwardsi. The crab is a member of the Crustacea phylum and is in the family Grapsidae. This crab species is found only in New Zealand on rocky shores. The rocky shore‚ where the crabs studied in this investigation were found is quite exposed. There is a large rock platform that provides small crevices and small rocks which help to protect them from wave action and predators

Testing this could be done by using a Petri dish full of agar and testing different bacteria on it to see if the bacteria obtained is gram positive or gram negative. My hypothesis is there will be a lot of bacterial growth on all of the plate. Materials and Methods -Petri dish containing nutrient agar -Cotton swabs -Sharpie A Petri plate containing nutrient agar was used in the experiment. A sharpie was used to section off four quadrants of the dish for the different bacteria. Cotton swabs
