wood block across a surface to determine whetherthe surface area ofthe block orthe type ofsurface affectsfriction. We found that the surface area of the block did not change the coefficient of kinetic friction‚ while the types of materialsin contact were directly related to the coefficient of kinetic friction. INTRODUCTION Friction is a part of our everyday life. Nearly every movement we make involves friction‚ and we have instinctively learned to take advantage of friction‚ or the lack

Aim: To investigate and compare the distribution density of stomata in the upper and lower epidermis of a dicotyledonous leaf. Stomata are the principle means of gas exchange in plants. Stomata are small pores they are controlled by guard cells which control the opening and closing of stomata. Stomata allow carbon dioxide to enter the plant‚ and allow water and excess oxygen to escape. About 90% of water is lost from the leaf during transpiration. The number of stomata on leaf surface varies among

The experiment was conducted at the Human Kinetics Program (HKP) Building in the University of the Philippines – Baguio. The terrain was prepared by distributing an even layer of gravel on the ground‚ and the background was covered by black cloth spanning the length of the terrain. The subject was also dressed in black to match with the background. The boules‚ jack‚ and significant joints and points on the subject’s body were marked with green bands to contrast with the background. A throwing circle

Combustion Background For this science experiment‚ we will be looking at the differences in calorie count between a food label and and the amount we measure in a lab. For this lab‚ we will be experimentally measuring how many calories are in different types of food. Before we begin the lab however‚ we need to investigate the science behind it. Firstly‚ we need to figure out if this project is even possible. Luna Abdallah et al created an experiment making it possible. To measure the amount of calories

2009 Ecology – Friday Parasitic Crab Lab Background: Mellita quinquiesperforata‚ commonly known as the sand dollar‚ is a familiar urchin on Florida coastlines. The species is flat and disk shaped that nestles into shallow sandy waters to protect itself from waves and predators. Dissodactylus mellitae is a parasitic crab that feeds on the spines of the hosting sand dollar where it remains its entire life. This study was arranged to observe the distribution patterns of crabs on various sizes of

We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface effects friction. We found that the surface area of the block did not change

does the different concentration of hydrochloric acid have to the rate of diffusion of agar that is dissolved with sodium carbonate and phenolphthalein? Introduction Diffusion is a process where the molecules intermingle as a result of their kinetic energy of random motion and is the net movement of like molecules down their concentration gradient‚ which is the energy inherent in their constant molecular motion makes them collide and careen outward from the region of higher to lower concentration

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity
