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

Lab Practicum‚ Micro 200‚ study guide When you did your hand wash experiment‚ you decided a variable to test‚ say‚ hot vs cold water‚ you called this variable an “experimental variable” since it was the variable you were testing experimentally. In order to get meaningful data‚ you need to keep other things the same‚ for example the washing time had to be the same for both‚ you called the washing time a _Control_______ variable. Through the semester‚ you have used two bacteria that produce

ENZYME LAB REPORT 1. In your own words‚ define objective qualitative and objective quantitative data. DO NOT USE EXAMPLES AS YOUR SOLE DEFINITION. (3) There are two different types of information that can be obtained from research. The types of information that can be obtained are quantitative and qualitative data. Research results are considered qualitative when the results can be answered with a simple statement of yes or no. Qualitative data does not attempt to give a numerical value; instead

Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that
