    Force is required to produce motion in a body. Once it gains motion‚ it will‚ without any further force‚ keep on moving with uniform velocity and zero acceleration only in ideal case where there is no friction force. If friction force was completely removable‚ everything in the universe would then keep on moving without any external force once it was set into motion. But it is a fact that friction can never be completely removed‚ thus the notion of ever uniform velocity is not possible in this real

    An Experiment of Adaptation Introduction: Throughout history of time‚ organisms change in relation to their environment‚ consequently‚ adaptation is an essential property of life. This experiment is designed to test the adaptation of Drosophila melanogaster. This kind of insect is also called fruit flies‚ it has been widely used in scientific research because it has a short life cycle about two weeks and it is easy to keep large numbers of them (Manning). Two groups of this species will be used

    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 4mL of Paramecium to 25mL of 0.2M NaCl and 225mL of Dryl’s solution‚ then Paramecium

    Purpose: Can the penny hold more drops of water or more drops of the MYSTERY liquid? Research: Cohesion- The state of sticking together. Pennies can hold more water because soap reduces the cohesion of water and the water molecules break apart and can’t stay on the penny. Hypothesis: The penny will hold more a larger number of drops of water because water is more cohesive than the “mystery” liquids Variables: Independent variable: Penny Dependent variable: Number of Drops of Water Control

    The purpose of my experiment is to determine which temperature will allow Luminol to glow at its greatest capacity. My hypothesis is that the glow will illuminate for the longest time in a cold temperature because it will take longer to dissolve. I also predict that in the warmer temperature‚ the glow will be at it’s brightest. Luminol is a chemical‚ which exhibits chemiluminescence with a blue glow. It is a solid that is soluble in most polar solvents‚ but insoluble in water. Luminol is widely
