Aim: The rate at which a reaction occurs‚ or takes place‚ is affected by various factors‚ such as the temperature at which the experiment is conducted in‚ the pressure which is given‚ the surface area which is exposed‚ use of catalysts‚ and the concentration. In this investigation‚ I would be investigating the affect of surface area‚ or particle size‚ in the rate at which a reaction occurs. Background Information: The more finely divided the solid is‚ the faster the reaction happens. A powdered

To Investigate the Effect of Varying pH on the Rate of a Reaction Catalysed by Trypsin Aims I hope to determine the effect of varying pH on the rate of reaction catalysed/controlled by the enzyme trypsin. Method 1. Add 4cm³ of the 2% trypsin solution in to 6 test tubes labelled A-F 2. Add 4cm³ of the appropriate buffer solution to each. ( I will be testing pH 4‚5‚7‚8‚8.8 and 10) 3. Add 4cm³ of distilled water and 4cm³ of the appropriate buffer solution to 6 control test tubes labelled CA-CF to see

USE OF ONION ROOT TIPS FOR MITOTIC DIVISION OBSERVATIONS Introduction The zone of cell division on the onion root tip is a great place to observe mitotic cell divisions. Through the observation and comparison of different regions of the root tip‚ the duration of mitotic stages and mitotic indexes are determined for the various divisions of the root tip. Methods Each group used a compound microscope to analyze the different sections of the onion root tip. The root tip was visually
