EXPERIMENT 2 Measurement of g: Use of a simple pendulum OBJECTIVE: To measure the acceleration due to gravity using a simple pendulum. Textbook reference: pp10-15 INTRODUCTION: Many things in nature wiggle in a periodic fashion. That is‚ they vibrate. One such example is a simple pendulum. If we suspend a mass at the end of a piece of string‚ we have a simple pendulum. Here‚ the to and fro motion represents a periodic motion used in times past to control the motion of grandfather and cuckoo

Organic Lab 2 February 14‚ 2009 Experiment 4: Borohydride Reduction of 2-Methylcyclohexanone Introduction: When learning about reduction reactions‚ we know that the addition of nucleophilic hydride anion (H-) to the carbonyl group will in turn result in the reduction of aldehydes to primary alcohols. Borohydride‚ and Lithuim aluminum hydride are commonly used as reducing agents. We can note that both of these reagents have a (H-) anion‚ hence it will be a powerful base and also take the

Stinson‚ Margie Biology 210 Lab Questions: Phylum Annelida You will learn the answers to most of these questions in class and in lab. Great resource: http://www.bumblebee.org/invertebrates/ANNELIDA.htm 1. What does the word annelida mean? 2. Recall‚ some of the nematode worms appeared superficially to have external rings. Describe true segmentation in annelids. How is the true segmentation in annelids differ from having rings around the ectoderm as in nematodes? 3. What two layers
