Lab Report – Strong Example Problem/Question Does using a base coat before painting nails prevent chipping? Background Information When painting nails‚ some manicurists use a base coat before applying the polish. The purpose of a base coat is to help the polish stick to your nails more easily. Base coats also help to protect your natural nail from the staining effects of colored polishes. Ridge-filling base coats fill in the grooves and cracks in the nail to create a smoother appearance

Lab 3 : Techniques in Microscopy Title : Preparation of light microscope observe cell organisms. Objective : To observe and investigate the cell structure under the light microscope. Introduction A microscope is an instrument used to magnify and resolve a specimen. It is important to know several important features of microscopy which involves magnification‚ resolution and contrast. Magnification is the enlargement of a specimen while resolution is the ability to distinguish detail or the

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration

Abstract This lab’s purpose was to test the patterns of percolation in various places. This lab tested how soil would absorb water based on different places. Distance from a group of trees‚ distance from a swamp‚ and different types of soil were tested. From the results collected‚ you can not prove‚ but you can infer that the ability to absorb increases as you go farther away from a swamp‚ and a group of trees. The ability to absorb also increases based on how much silt is in soil. Introduction
