Joe Schmoe Period 3 March 8‚ 2013 Lab Report: Empirical Formula of Zinc Chloride (ZnCl) * Purpose The purpose of this experiment was to learn how to determine the empirical formula. Empirical means “based on experimental evidence.” * Experimental Design The reaction that occurred was the reaction of the elements Zinc (Zn) and Chloride (Cl) by mixing a piece(s) of Zinc and 50mL of Hydrochloric Acid (HCl). The amount of Zinc was determined to be between 1.00g and 1.25g. As the reaction

Lab Report 1: Natural Selection Introduction: In today’s lab we learned how natural selection and survival of the fitness took place in Darwin theory by testing it out with four different utensils which were Spoon‚ Fork‚ chopstick‚ and clothespin which represent the four different types of bird beaks. Our goal was to see which one utensil ( bird beak) would outcome the other four utensil ( bird beak) by being able to survive with the limit amount of food‚ the environmental chances‚ and see who

These kinds of feedback is significantly different from those we receive when touching and typing on a keyboard. Learning by doing Together with neurophysiologist Jean-Luc Velay at the University of Marseille‚ Anne Mangen has written an article published in the Advances in Haptics periodical. They have examined research which goes a long way

experience is through the media. In everything we see in the media between movies that we watch‚ reality shows or even the news there’s always a message behind it or a concept that many of us don’t understand. In the media there is a lot of racial stereo typing showing the audience how people should look or how a certain race behaves. Basically categorizing different races and cultures sometimes are making jokes about a certain race or showing a negative message about certain people. What does the average

I.Purpose The purpose of this lab is to show how potential energy and kinetic energy is shown and transferred using a model rollercoaster. This lab also demonstrates the Law of Conservation of Energy. II.Introduction Potential and Kinetic energy have a very big relationship. The Law of Conservation of Energy states that “Energy cannot be destroyed or created‚ but can be transformed or transferred.” This lab will help demonstrate this law and show the conversion between Kinetic and Potential
