Nool‚ C. P. R. M. Orpilla‚ K. L. Pascual College of Engineering‚ Adamson University Abstract THIS EXPERIMENT IS ABOUT THE SPECIFIC HEAT OF VARIOUS METALS. THE MAIN OBJECTIVES OF THIS LABORATORY ACTIVITY ARE TO DETERMINE THE SPECIFIC HEAT OF METALS AND TO COMPARE THE EXPERIMENTAL RESULT OF SPECIFIC HEAT FROM THE STANDARD VALUE. ANOTHER PURPOSE OF THIS EXPERIMENT IS TO DETERMINE THE RELATIONSHIP BETWEEN THE SPECIFIC HEAT OF THE MATERIAL AND THE CHANGE IN TEMPERATURE. LASTLY‚ IS TO

In beetroot cells the red anthocyanin pigment occurs in the vacuoles. Each vacuole is surrounded by a membrane and outside it the cytoplasm is surrounded by the plasma membrane. These membranes are too thin to be seen but we can draw certain conclusions about their properties. Hypothesis; Membranes of the beetroot cells are composed of phospholipid bilayers. These form a stable fluid mosaic and retain their contents. The fluidity of the mosaic increases with temperature and high temperatures

a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia oleracea (Spinach)‚ Brassica oleracea (Broccoli)‚ Solanum tuberosum (Russet Potato)‚ Malus domestica (Apple)‚ and Allium cepa (Onion). The five different catalases from the sources will all be used

NAME: Donna Ha TITLE: Measuring the Rate of Osmosis Using “De-shelled” Chicken Eggs INTRODUCTION: In order to fully understand the concept of this experiment‚ one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that is highly concentrated to another area in which its concentration is lower. Cells contain fluids and are surrounded by fluids; in order for a cell to function it is required to be in a balanced state. The

Meiossis and Genetic Diversity in Sordaria Meiosis and Genetic Diversity in the Model Organism‚ Sordaria. By: Katie Fiorillo BIO110 Lab TA: Lauren Smith October 30‚ 2012 A. INTRODUCTION: In this lab‚ the organism Sordaria fimicola was used to explore factors contributing to genetic evolution of sexual reproduction. These organisms are found in “Evolution Canyons‚” which occur when two mountain slopes with very different climatic conditions congregate with a comparatively small valley

case osmosis will cause more water to move out of the cell than will move in the cell and the cell will shrink. In this case‚ we say that the solution is “hypertonic”. Learn more about osmosis and diffusion from Chapter 3 of your textbook. CELERY EXPERIMENT We can place celery in three different water solutions to observe the effects of osmosis on the celery stalks. Salt will serve as our solute to

Determination of : Titration of a Weak Acid Introduction: We will be using the LoggerPro and LabPro in order to help us determine our data. The purpose of this experiment is to follow the changes of pH during the titration of an acid and a base in order to determine the of the weak acid‚ . is a constant for a given acid at a given temperature. In this experiment we determined the Ka using two different methods: 1) the measurement of the pH of a solution containing a known concentration of a weak acid‚ and 2)

EXPERIMENT Materials 200 Toothpicks Timer Tape Controls 50 toothpicks per trial. 120 seconds per trial. The same brand of toothpicks. One toothpick broken at a time (except for Mutation Trial 2). One toothpick broken into two pieces equals one reaction. Broken toothpicks cannot react again. (Toothpicks can only be broken once) The toothpicks are broken between the thumb‚ index‚ and middle finger (toothpickase). Break two toothpicks at a time (Trail 3). Tape the index finger and thumb.

Data Collection: The aim of this experiment was to test the weight of six potatoes before and after being put into different sucrose solutions. The following data was observed and collected throughout the experiment. Observations: -Qualitative: The potatoes were: Tubed shaped Yellow in color Initially hard in texture -Quantitative: Table 1: Weight of the potato in grams before and after placed in a different concentrations of sucrose solutions. Sucrose solution (M) Weight Before (g) ±
