(3 points) Score 1. How do you calculate magnification on a microscope? Answer: The shortest lens is the scanning objective; you use it to locate the object on the slide. The medium-length lens is the low-power objective. The longest lens is the high-power objective. Multiplying the power of the eyepiece

Leila Espinal Grade 8 O.L.C.A. November 20‚ 2013 Lab Report 1. Problem: To find the density of a Hershey chocolate bar. 2. Hypothesis: I think the chocolate bar will gradually decrease in density as it gets smaller. 3: Materials: 1 whole Hershey chocolate bar‚ ruler‚ triple balance beam‚ tray‚ calculator. 4. Procedure: First‚ find the mass‚ volume‚ and density of an entire Hershey Bar. Then‚ systematically‚ break off one section at a time to calculate the

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

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.

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
