graduated cylinder. The 50g of catalase and the 50ml of distilled water will be put into a blender and blended until liquefied. The catalase solution will then be introduced to a Buchner funnel filtration system to separate the catalase extract from any solid particles left over from the blending process. This step will be repeated until all of the catalases have been blended and filtered. Next‚ 5 ml of hydrogen peroxide will be measured out using a graduated cylinder. It will then be poured into a small

Formal Lab Report | Chemistry | | Student name: Sara Hattar Grade: 10 ”C” | | Teacher: Christine Ziadat | | | Title: Investigating the effects of changing the concentration of an acid on the rate of reaction between HCl and Magnesium. Aim: In this experiment we are going to see the effects of using three different concentrations of HCl when added to Magnesium metal on the rate of reaction. Hypothesis: If the concentration of the acid increased in reaction between HCl (the acid)

Biosphere Lab Report A biosphere can be defined a lot of different ways. Our interpretation of a biosphere is the area in which life can be contained within. In the case of the earth‚ it means as high as a bird can fly and as deep as fish can swim in the ocean. A biosphere is a closed system that has a constant flow of energy between the organisms living within it and it needs nothing outside of itself but sunlight to continue to be sustained. At the University of Arizona‚ they attempted to build

Murphy Grand Canyon University: Physics 1 Lab September 5‚ 2013 Testable Question: Circular objects; what happens to the circumference as the diameter changes? Hypothesis: As the diameter increases‚ the circumference will increase in a proportional linear way. This is because as the diameter increase‚ the object will as well. Variables: Independent- The diameter of the circular objects. Dependent- The circumference of the

Melting Points Elizabeth McGrail Organic Chemistry I 25 January 2013 ABSTRACT The objectives of this lab are‚ as follows; to understand what occurs at the molecular level when a substance melts; to understand the primary purpose of melting point data; to demonstrate the technique for obtaining the melting point of an organic substance; and to explain the effect of impurities on the melting point of a substance. Through the experimentation of three substances‚ tetracosane‚ 1-tetradecanol and

turn off the primary production. Darkness has no effect on respiration. This is because cellular respiration is actually the reverse process of photosynthesis. Oxygen is a necessity of life requirements for basically all living organisms.* In this lab we are testing how different levels of salinity in the water indirectly affects the gross primary productivity in aquatic plants. To measure this you would use the light and dark bottle method. Only respiration (R) can occur in the bottle stored in

Exocytosis Lab Report Rough Draft Abstract: In Paramecium caudatum‚ trichocysts are 10^3 secretory vesicles that are released from the cytoplasm. We first observed how the presence of Alcian blue dye triggers normal secretion of trichocysts‚ and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is

The results for trial two also took a while for changes to show up. By the end water‚ salt and nail polish remover evaporated the most. The units and measurements were as well checked daily for specific change. The changes in trial three made the numbers different from the other two trials. Some of the
