Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors. Materials Lab stand Protractor Cardboard Fishing line Stopwatch Weights Hook for weights Tape Ruler Weighing scale Logger Pro Variables Independent Angle of release Dependent Period Length

Separating Substances: Identifying Food Dyes with TLC Background The color of food is an integral part of our culture and enjoyment of life. Who would deny the mouth-watering appeal of a deep-pink strawberry ice cream on a hot summer’s day or a golden Thanksgiving turkey garnished with fresh green parsley? Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow color

Human ECG Abstract The purpose of these lab exercises is to understand the function and importance of an electrocardiogram. This lab will demonstrate how stress levels or different elevations can affect human heart rate. Furthermore‚ the equipment used in the experiment will show the functions in the right and left arm; as well as‚ in the right and left ankles. Finally‚ the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate. Introduction
