Materials: To complete all steps and smoothly complete the lab we first needed an almond‚ which what will be burned to find the energy and calories. Next we needed a paper clip to straighten out and put the almond on as a safe and efficient way to burn the almond. A scale and small aluminum-weighing dish were needed as well to weigh out the almond and paperclip. The lab also required a graduated cylinder‚ test tube‚ distilled water‚ thermometer‚ a Bunsen burner‚ a sparker‚ a calorimeter and safety

in the 20% solution. 7. Average the molar masses you calculated in questions 3 and 6. 8. The formula for antifreeze is C2H6O2. Calculate its molarmass using the periodic table. 9. Calculate your percent error. Conclusion: This lab was a phenomenal success! The purpose of determining the freezing points of water‚ 10% antifreeze‚ and 20% antifreeze was not only accomplished‚ but also done so in a splendid manner. The net figures of our experiment were less than 5°C off from the

Biology 103 Lab Spring 2013 Does a larger head mean higher intelligence? Introduction: Some say a larger head gives room for a bigger‚ more intelligent brain. Men‚ thought to have larger heads simply because they’re… well men. In which case‚ men have a larger head size than women‚ therefore making men smarter than women. Methods: My partner and I went ahead and measured the heads of 15 people in our class‚ 5 of them male and 10 of them female. We used a measuring band to measure‚ to

simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus

Effects of Crossing Over in Sordaria fimicola Abstract Sexual reproduction in organisms is a cause for genetic variation. This can be seen through the process of meiosis in Sordaria fimicola because of the effects of crossing over and independent assortment that occur in meiosis I. Before performing this experiment we hypothesized that we would be able to see that crossing over did indeed occur in the S. fimicola. We tested our hypothesis by growing our own culture and observing it under a
