analyze soil to see if bacteria could live in that environment. The reason why I did it was because I wanted to find out where in the environment bacteria and fungi can live. In order to do my study I had to collect a sample of soil and put it in a dish. After I did that I could look at it underneath a microscope. I found that bacteria did in fact live in the soil so the soil was a sustainable environment for the bacteria to live. Introduction: The problem that I investigated was where in the

Indirect distillation (or drying) methods involve the measurement of the weight lost due to the evaporation of water. The open dish method is applicable to a wide range of foods. The vacuum oven method is particularly recommended for food when decomposition is likely to occur. The infrared balance method is used for rapid routine work. The influence of water activity on food

Introduction: A balanced chemical equation has reactants and product that has to represent a formulae. The amount of each element‚ number needs to be the same in either side of the equation. (E.g.‚ HCl(aq)+NaHCO3(s) reacts to produce NaCl(aq)+H2O(I)+CO2(g)‚ this is the equation given for this lab). This help us view the study of Law of Conservation of Mass‚ when either side of equation is equally balanced. The calculation for formula mass helps determine if you need to convert grams to a particular
