Thickness of Aluminum Foil August 21‚ 2014 Purpose: To determine the thickness of aluminum foil through the use of the density formula applied to gathered data. Theory: The thickness of aluminum foil cannot be directly measured. In order to find the thickness‚ many pieces of data must be obtained and used in the density formula. The data that must be obtained is the length‚ width‚ and mass of the aluminum foil. These need to be collected because they will complete the formula: Density = mass /

Lab Section 1 Wednesday 1:10-4:00 M. Moore Zoology Lab #1 Morphology of Dragonflies In analyzing the morphology of dragonflies by looking at two different time periods and the water levels‚ data was found to illustrate that body size might be directly influenced by water levels. By looking at the dragonfly species Sympetrum vincinum during the 2001 drought and 2008 normal rainfall‚ the data showed that there was no statistical difference in abdomen depth (p value 0.20741). There was a

1 ) The sum of the digits of a two-digit number is 7. When the digits are reversed‚ the number is increased by 27. Find the number. 2 ) A passenger jet took three hours to fly 1800 miles in the direction of the jetstream. The return trip against the jetstream took four hours. What was the jet’s speed in still air and the jetstream’s speed? 3 ) These circles are identical. What is the value of x ? 4 ) Solve for x using these two equations: 2x + 6 = y; y - x = 2 5 ) The perimeter and the

The sizes of Paramecium September 17‚ 2008 Wednesday Lab I am writing about the testing of sizes on Paramecium caudatum and bursaria and how they differentiate from one another. In comparing the two specimen’s size I found that the Paramecium caudatum was larger in size than the bursaria. Paramecia are unicellular organisms and are usually less than 0.25mm in length and covered with minute hair-like projections called cilia. They are characterized by their cilia which are

The Rate of Locomotion dependence on hind leg length and body mass for the Tenebrio molitor beetle. Abstract The effects of leg length and body mass on the Tenebrio Molitor’s rate of locomotion were investigated under laboratory conditions. The performance (running speed) was accessed for 37 Tenebrio molitor with different hind leg lengths and body masses. Running speed is important for a variety of activities (e.g. searching for prey and mates‚ dispersal‚ etc.). Therefore‚ increased
