    ABSTRACT. In this experiment‚ we test factors which affect friction. We pulled a 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

    Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew

    Group 2 Science Investigatory Project I Title: Potato Battery II Objective: We only need a potato‚ a couple nails and a piece of wire to make a potato battery. It’s a fun science project that helps show the way things work in a battery by using everyday items we see around the house. The goal is to learn more about electricity‚ and possibly a few new science terms along the way. III Materials: * Two Potatoes * Two short pieces of heavy copper wire * Two common galvanized nails

    Investigation the effect of the organic solvents on the cell membrane of the beetroot Objective: To investigate the effect of different organic solvents‚ such as alcohol and paraffin oil‚ on the cell membrane of the beetroot by using the red pigments in the beetroot as indicator. Hypothesis: Organic solvents dissolve the organic matter in the cell membrane (such as phospholipids). This destroys the cell membrane‚ and the permeability of the cell membrane is disrupted casing red pigments to leak out

    the osmolarity point of potato cells‚ where it is investigated how osmosis changes the weight of the potato cells‚ measured by the percentage change between the initial and final mass of the potato? Independent Variable: Increasing sucrose concentrations Dependant Variable: Mean percentage change in mass of potato cells All cells have a protective barrier‚ one which selectively allows substances to enter and exit the cell. This is known as a cell membrane. Some cells are semi-permeable‚ which
