I was astonished when I heard the news‚ I received Thursday afternoon from my manager! Pop Chips asked me to be in an ad for them! If you have never heard of Pop Chips‚ they are all-natural Potato Chips and are fantastic. As we make our way to the photoshoot‚ I had this weird feeling in my stomach. I think it was just the rush of excitement and nervousness getting to me. When we arrived‚ I was pulled straight out of my car and escorted to my dressing room‚ so we could get started ASAP. It took a

Race Your Marbles to Discover a Liquid’s Viscosity Which Liquid Has the Highest Viscosity? In this project we will determine the viscosities of 5 separate liquids. The liquids we will test are corn syrup‚ honey‚ vegetable oil‚ milk‚ and water. We will find their viscosities by dropping a marble into each of these liquids and measuring the time it takes for it to reach the bottom. Before we conduct the experiment‚ we must first understand what viscosity is. “Viscosity is the quantity that describes

Electrophoresis of Amino Acids Introduction: Electrophoresis is a separation technique based on the movement of charged ions under the influence of an electrical field. This technique is primarily used for the separation of amino acids and peptides on the basis of their charge. All amino acids contain ionizable groups that cause the amino acids‚ in solution‚ to act as charged polyelectrolytes that can migrate in an electric field. The amino acids with a net positive charge will migrate toward

"Wing’s Chips" is a short story by Mavis Gallant with a powerful message. The theme of this story is that even though many people have different backgrounds and dissimilar views on what is right and wrong‚ they want to be respected and accepted for who they are. "Wing’s Chips" focuses on three separate cultures‚ who in the end‚ learned to respect each other in a subtle way. A French-Canadian town is the setting for this short story. A river divides this town‚ with an English community on the opposite

expected melting point. After its temperature reached the plateau‚ the temperature increment was set at 1°C per minute‚ and the melting point range of 152°C-154°C was recorded. After standardizing the melting device‚ a small sample of unknown carboxylic acid was placed in a capillary tube‚ and an arbitrary plateau of 200°C was set. When the sample started to melt at 150°C‚ another capillary tube containing a small amount of unknown sample was placed in the melting device‚ and the plateau was set to 135°C

the experiment was performed to conduct quality control analysis on two commercial products to determine the amount of acid or base active in these two products and then compare the results to those of the manufacture. This was done through the preparation of standardized acid solution and standardized base solution‚ and through titration. The purpose of titration was to determine the concentration levels of the commercial products being used. Methods and Materials Week One: the experiment started
