Stephen Pidliskey 09/15/07 P1 Park ISOPOD BEHAVIOR LAB REPORT Background Information: In our lab we were working with isopods‚ also known as pill bugs or rollie pollies. The isopods that we worked with were land isopods. They like to live in moist places under untouched objects such as boards‚ bricks‚ rotting logs and or rocks. Basically‚ they will live anywhere! If you are lucky enough‚ you can even find them next to buildings where it is moist and if there is food. All living organisms like

Ahmad Shrab . Introduction This lab is purposed to familiarize basic equipment and techniques used in the study of microorganisms. In addition‚ learn some basic techniques used in identifying prokaryotes and make and view microscope slides of some common prokaryotes. In this lab ‚ I worked two experiments ‚ the first one is cultivation bacteria "colony "‚ and When microorganisms are cultivated

Benjamin Kleveland 502 October 26‚ 2014 Lab 7 Report Lights Distance and Wavelength Effect on Photosynthesis Photosynthesis and cellular respiration are often mistaken as the same thing. Although they are similar in many ways‚ photosynthesis and cellular respiration are the exact opposite of each other. Not figuratively‚ but literally the reverse (Photosynthesis). They incorporate the others products while adding some outside energy to create a never ending cycle. This brings us to the photochemical

Title: The Effect of Nicotine on the Heart Rate of the Lumbriculus Variegatus Introduction: Background- This lab is being done to demonstrate the effects of stimulants on the circulatory system of blackworms. In this lab‚ the stimulant we have chosen to use is Nicotine. A stimulant is an agent that causes increased activity‚ especially in the nervous or cardiovascular systems. In this lab‚ we will put blackworms into the Nicotine to look at the differences in pulse rates when compared to a control

Organic Lab Trial 1 Trial 2 Trial 3 Observations We added the 30ml of warm water with 4.7 grams of borax powder in to the cup labeled ‘Borax Solution’ and also added a few dots of green food coloring. We then stirred it until all the solutions were completely mixed. When this happened the borax and water turned into a watery green solution. then we added 15ml of glue in the cup labeled ‘Ball mixture’ and added the mixture we made

“Morton Salt“ “No one knows Salt like we do”. Morton Salt generates a never-ending supply of new products in covering all possibilities where salt can be used and is not focusing on only one type of salt e.g. Culinary Salt. During over 160 year’s history‚ Morton Salt never stopped developing new salt products and finding new niche markets. Salt is not seen as a mundane product that is only used to salt e.g. food but even more as science. Morton Salt is presenting on his website how various salt can

betacyanin will leak out and produce a red colour in the surrounding water. More cells being damaged will cause a higher red colour intensity in the solution. The beetroot cylinders were repeatedly washed following cutting until not more colour appeared in the wash water. The aim of this experiment is to observe the effect of physical and chemical stress on the membrane permeability of beetroot. METHOD A large beetroot was washed with water. 14 cylinders were cut‚ all to the exact length (approx. 1cm with

Panacetin was dissolved in the dichloromethane. (b) Failing to mix the aqueous and organic layers thoroughly during the NaHCO3 extraction would lead to little to no production of aspirin precipitate. The aqueous layer contains sodium hydroxide and water‚ whereas the organic layer contains the dichloromethane‚ aspirin‚ and the unknown. If the HCl has nothing to react with in the aqueous layer following mixing (i.e.‚ sodium acetylsalicylate)‚ then little to no solid aspirin will be produced. Furthermore
