allow an object to move is dissipated into heat energy and will not return to the system once the movement stops. Specifically‚ this lab will calculate the coefficient of friction. Unlike most coefficients in Physics‚ friction behaves differently depending on whether the object is at rest or at motion.

Purpose Determine the acceleration in a quick sprint. Question What would the participant’s acceleration be if he/she sprints forward in a positive direction? Hypothesis/Prediction When a person sprints forward‚ it means he/she speeds up. Consequently‚ the acceleration should be positive. When the velocity accelerates at a constant rate‚ the acceleration should remain constant. Therefore‚ if the participant is moving toward a positive direction and the speed increases‚ then the acceleration

Finally‚ saponification will be learned. PROCEDURE: Carboxylic Acids and Their Salts: Characteristics of acetic acid: 2mL of water and 10 drops of glacial acetic acid was placed into a clean‚ dry test tube. Before

G. Y. S. Period: 6 09/11/12 Osmosis Lab I. Objective: The purpose of this lab is to put the solutions in chronological order from least to most molarity. If the solutions are hypertonic then‚ the water will go in and the order of the substances will be C‚ D‚ A‚ B‚ E. II. Materials and Methods: See attached page. Results: Table 1.1 III.

potential to damage crops extensively‚ and thus‚ damage society as well through shortage of food or even famine. In addition‚ in countries that depend on the production of agricultural goods like Canada‚ the effects of acid rain can be tremendous. In this lab‚ we have chosen to examine the effects of acidic and basic environments on radish plants (Raphanus sativus)‚ by implementing varying pH levels of buffer solution into the soil. We have allotted a total of four days (Tuesday‚ April 10‚ 2012- Friday April

are one of the easier species of aquatic life to care for‚ their respiratory systems are just as complex as any other fish. Like other aquatic animals‚ goldfish have a one-way flow respiratory system. This means that their respiratory system pumps water through their gills and back into the water supply to absorb oxygen. Gills--which are the organs that most aquatic animals use to breathe--consist of complex filters that extract oxygen from the water.” There are many factors that can affect

cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon dioxide levels decrease as oxygen levels increase and glucose is produced when light dependent reactions occur. Light energy is absorbed by photo
