Eggs are a key ingredient used to make a foam. Investigate the functional and chemical properties of eggs and other ingredients when making meringue. Chemical and Functional properties of eggs: Background information Eggs give a smoother texture to microwaveable dishes‚ frozen dishes are better to freeze. The yolk and the egg white cam be used in many different ways for different products of food. Eggs contain a lot of protein and a balance of other nutrition. Some producers require fresh eggs to

Department of Chemistry [Colligative Properties & Osmotic Pressure] Purpose : The experiment this week had two different purposes. The first is to teach us about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis

Colligative Properties 202-NYB-05 (Group 06.) By: Jordan Hribar 1034044 Partner: Anthony Cuillierier Teacher: Daniel Baril Experiment Done: February 23rd‚ 2011 Experiment Number 2. Introduction Some of the properties unique to solutions depend only on the number of dissolved particles and not their identity. Such properties are called colligative properties. The colligative property that will be examined in this experiment will be the freezing point depression as an example

Production and Properties of Metals Mr J E Chuter‚ Cert Ed 2012 En No 20100292 Introduction I have decided to produce a project based on the production and properties of metals‚ as although I have worked as a welder for over 30 years‚ and a welding teacher for the last 2 years on apart-time basis‚ I felt I didn’t know enough information on the material that I work on‚ on a daily

the okay to do the experiment‚ I grabbed the girls and went to work. The experiment I picked was the conservation concept‚ where the idea that merely changing the appearance of objects does not necessarily change other key properties. In other words‚ just because I put the same amount of water in a bigger case‚ doesn’t change how much water there is. I predict that both the girls would fail at conservation concept‚ and always

Environmental Science The Scientific Method Amber Steadham October 31‚ 2012 Abstract: We conducted several experiments using the Scientific Method. We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical
