... An experiment to determine the actual properties of different types of toothpastes. Aim: To investigate the properties of different brands of toothpastes, and so determining which is best for daily use and which is however not. Method: The following is the method to show how this experiment was conducted: 1. A small volume of toothpaste was added into a small 25cm3 beaker, and 10cm3 of water was added to the toothpaste in order for the toothpaste to reduce its concentration, and so that the toothpaste was suitable for the experiment. This was done for all of the brands of toothpaste. 2. A drop of each type of diluted toothpaste was placed onto a glass slide by using a glass rod, and a cover slip was placed upon the specimen, and was made sure to be placed at a right-angle in order to prevent air bubbles for forming, which could affect the specimen to be experimented. 3.
