Chemical Properties of Egg Tempera Art is traditionally viewed as a creative process far removed from science. However‚ beyond the imaginative efforts that contribute to the creation of a work of art are the physical materials that are used as the medium. While science is not an essential part of the thought and design process‚ an understanding of the chemical properties of different art media is integral to creating a work of art that will not only match the artist’s vision but will also stand

Variables: * With the building of our cars‚ we were measuring the mass of the egg‚ mass of the car‚ time for it to go down the track‚ and the width so that it would fit down the track. The variable that affects our cars the most is the mass. If your car weighs to little‚ it will go at high speeds and the egg will most likely

Liquid CO2 Extraction of D-Limonene This convenient‚ effective and inexpensive liquid CO2-based extraction of a natural product (D-limonene) provides an engaging example of natural products extraction using an alternative solvent (liquefied CO2). Because the procedure can be carried out in a polypropylene centrifuge tube and uses crushed dry ice as its CO2 source‚ it provides an inexpensive alternative to the equipment-intensive extraction with supercritical CO2. A short video clip is available

“In what way can a drop an egg off of a building without it cracking?” when I first asked this question a believed that it would be an easy task. I however‚ was very wrong. As I came up with ideas Mr.Billy kept on turning them down saying “that isn’t allowed.”‚ but in my defence most of the things that were not allowed were not written in the rules. In the end our design was very successful in safely delivering the egg to the ground. With changes it probably could have been improved‚ I was happy

much weaker. Besides strength of the brew‚ growing conditions‚ processing techniques- and other variables also affect caffeine content. Certain types of tea may contain somewhat more caffeine than other teas. II. Methodology Firstly‚ the extraction must be considered. Three tea bags were opened and the combined weights of the tea leaves were taken. Recording the weight is necessary. The tea leaves were returned in the bags. The next step was boiling of the tea bags in 100 mL distilled water

Extraction of caffeine from tea bags ABSTRACT Caffeine extraction from the commercial tea leaves (Lipton Yellow Label Tea) that was done is multiple extraction. 4 tea bags were used in the experiment; tea leaves were weighed having 8.5333 grams. The leaves were boiled in a beaker with 150ml of water; the aqueous tea extract was transferred in a seperatory funnel mixed with DCM (20ml)‚ done thrice. The DCM layer was washed with 20ml 6M NaOH in the seperatory funnel; the organic layer was dried

and diffusion. In this experiment I began by calculating the volume of a fresh chicken egg. Then to determine the effect of osmotic pressure change on a cell I soaked the raw chicken egg in vinegar for 24 hrs‚ and measured the volume of the egg after the shell had been dissolved by the vinegar. The egg was then submerged in corn syrup for 1-24 hrs‚ then measured and recorded the new egg volume. Finally the egg was submerged in water for 1-24hrs‚ again the volume was measured and recorded. I then

With egg allergies becoming more common than ever before‚ I thought it would be an interesting experiment to see if replacing eggs in a recipe would make a big difference. In my experiment‚ I plan to use different egg substitutes in a cookie recipe and then conduct a blind taste test with about 70 testers to see which cookies were most preferred‚ both visually and in taste. After this‚ I will be able to conclude which egg substitutes‚ if any‚ work best in a cookie recipe‚ and what the necessary elements

Title: Egg Osmosis Purpose: The purpose for doing this lab is to show how Osmosis takes place. It is supposed to show how the eggs would react to a change in their environment. The way to show how it would change would be putting eggs in different controlled environments. Each of the eggs will be put in three different environments. Vinegar‚ Karo Syrup‚ and water. Each egg will have to have a documented reaction that each will have. Introduction: The lab will allow us to see and explain each
