The ten Petri dishes that exclusively did not contain an antibiotic in the bacteria culture served as the control. There were ten trials for the control and each level of IV. The experiment began by cleaning the work area and sterilizing it with 70% ethanol. Then trypticase soy agar (TSA) was poured into six groups of 60 Petri dishes (See Appendix 1). The dishes were labeled based on the antibiotic used and were left to dry and solidify at room temperature. After an hour‚ the dishes were placed in

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

condition. The experiment starts with two petri dishes‚ and we filled each dish with fifty radish seeds. We made our first observations about the seeds that we see. We labeled one petri dish “Control‚” and the other was labeled “Experimental.” The experimental petri dish was put in the freezer for seven days‚ and the control petri dish was set on the counter in the normal-temp classroom for seven days as well. After those seven days‚ the experimental dish was removed from the freezer‚ and we used

It was necessary to ensure no contamination of the spores. He then proceeded to distribute the spores around the dish and solution. After sealing the petri dish back up‚ I labeled the dish with our group name and date. Finally‚ the petri dish was placed inside of the culture dome to properly germinate. The second

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
