Research Question: At what speed will the helicopter fall by adding more paper clips to its base (the bottom)? Variables: Independent Variable: Amount of paper clips Dependent Variable: Speed Constant: I. Same Helicopter II. Same Timer III. Same height (2m) Hypothesis: My hypothesis is that the more paper clips added to the base of the helicopter‚ the speed will increase. I think this will happen because gravity will pull the helicopter down and the opposite force (air resistance)

Owl Pellets Introduction Owl pellets are masses of bone‚ teeth‚ hair‚ feathers and exoskeletons of various animals preyed upon by raptors‚ or birds of prey. Owls have weak stomach muscles that form undigested bones‚ feathers‚ and fur. Because they can’t break those things down they regurgitate them in the form of a ball called a pellet. Owls produce these pellets and regurgitated them approximately 20 hours after eating. The purpose of this lab is to dissect an owl’s pellet and investigate

Firth’s Ideal Observer Theory suggests that an ethical statement like “x is right” means‚ “any Ideal observer would react to x” (Firth‚ P. 209) by producing an alpha reaction. The following are the characteristics of an Ideal Observer: Omniscient with respect to the non-moral facts‚ omnipercipient‚ disinterested‚ dispassionate‚ consistent and “normal”. In this essay‚ I will attempt to explain and justify why opposition to the “omniscience” characteristic is the most powerful objection to the Ideal

ABSTRACT: Two separate variables were hypothesized and tested within the confines of the experiment on their effects on the productivity of lactase enzyme. The measurement of light absorbance levels of different solutions based on both the concentration of o-nitrophenol (ONP) as well as the pH of the solution tested. To begin with‚ differing concentrations of ONP were tested to find the absorbance levels of ONP. Three different pH values‚ 5‚ 6‚ and 7‚ in solution‚ were tested over a period of 8

Introduction Extraction involves dissolving a compound or compounds either from a solid into a solvent or from a solution into another solvent. Extraction is a method used to purify a substance by removing the impurities that was added to it. A solvent- solvent extraction is a type of extraction that is most commonly done by using two substances that are typically insoluble with each other. An acid-base extraction is a solvent-solvent extraction‚ in almost every case one of the solvents is water
