Paramecium can swim in the water. However‚ when you add different chemical into water‚ it will affect the swimming speed of the paramecium. The various students groups have individual experiment of how dose NaCl affect swimming speed of Paramecium‚ but the experiment did not show the result clearly to students. Therefore‚ after they finish the presentation‚ most of the students want to find out the chemical NaCl increases swim speed of Paramecium. Experiment Design The experiment prediction is if we add

task is to design an experiment to investigate one of the factors that affects photosynthesis. Once you have chosen which factor you are going to change then you should‚ if necessary‚ do some research to find out the best way to change this variable. Remember to think about how much data you need to collect to be able to draw meaningful conclusions and then how many repeats you might want to include making your results more reliable. Explaining why you have chosen to do each step will help ensure

What is Water Scarcity? Simply put‚ water scarcity is either the lack of enough water (quantity) or lack of access to safe water (quality) Water covers 70% of our planet‚ and it is easy to think that it will always be plentiful. However‚ freshwater—the stuff we drink‚ bathe in‚ irrigate our farm fields with—is incredibly rare. Only 3% of the world’s water is fresh water‚ and two-thirds of that is tucked away in frozen glaciers or otherwise The problem of water scarity is a growing one. As more people

Edward Dickson CHE101 DS-01 Experiment Date 7/21/2013 Report Submitted 7/21/2013 Title: Experiment #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

Stanford Prison Experiment In discussions of the Stanford Prison Experiment conducted by Philip G. Zimbardo in 1970‚ one controversial issue has been whether or not the experiment should have ever been attempted. On the one hand‚ Dr. Zimbardo and his colleagues argued that the experiment gave them a deeper understanding of human suffering and a greater empathy for their fellow man (Ratnesar 2011). On the other hand‚ one of the former guards contended that the experiment made him more hostile and

conduction experiment was to identify three different metal specimens by comparing their experimentally determined thermal conductivities to known thermal conductivity values of existing metals. The second objective of the experiment was to establish a connection between the thermal conductivities & temperatures of the metal specimens. Thirdly‚ the contact resistance of the interfaces between the specimens was to be determined. II. Theory Particles of a substance always interact with each other

Experiment E: Post lab Natasha Buckiewicz (130361780) IA: Matt Halloran Due: November 26‚ 2014 1. This experiment followed GCP number 8 which is reduce derivatives. This experiment did not use unnecessary derivation since the reaction was not modified in any way. No additional reagents were required so it did not generate a lot of waste. 2. Safer solvents and auxilaries (GCP #5) was not used in this experiment since the experiment used a solvent to complete the reaction. The reaction used both
