The Biological Importance of Lipids Lipids are organic compounds found in all types of plant and animal cells. They always contain carbon‚ hydrogen and oxygen‚ however the relative amount of oxygen is less than the amount of carbohydrates in lipids. Lipids are polymers and the long chains of repeating units are joined together in a condensation reaction where water is also produced. The most common types of lipids are triglycerides‚ phospholipids and waxes. Triglycerides are formed by three fatty

My artifact is a picture of an aluminum foil boat (The Richest Boat) that we had to create on Dr. Narayan’s class EDEE 4330. At first we were asked to create a boat with a piece of white paper‚ and we had to tape

experiment concerning Archimedes’ Principle to determine the density of solids and liquids using Archimedes’ Principle. For the density of solids‚ they had made use of spring balance to measure the mass of the metal samples‚ which were tied via string‚ in air and when immersed inside a 2000mL beaker‚ where H2O lies. They had computed the density of each sample metal using the formula: ϱs = maϱw / ma - mw and computed a percentage error. As for the density of liquids‚ they had filled a graduated cylinder with

Procedure: Using distilled water‚ premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius‚ Fahrenheit and Kelvin. Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle. obseRvations Data Table 1: Length measurements. Object Length (cm) Length

Measurement of Mass‚ Volume‚ and Density through Archimedes Principle Overview: The purpose of this experiment was to measure the density of a solid and a liquid using Archimedes principle. Archimedes is one of the greatest inventors and mathematicians of all time. The principle we used in this experiment was discovered when Archimedes stepped into a full bath tub. Using Archimedes principle‚ we were able to determine the density of a lead rod‚ water‚ and an unknown liquid. Physical Data:

This program is really fun for me because I get to build a robot and see how I can fix it and make it better it teaches me social skills because when we have our interviews I have to socialize and I learn basic science‚ I learn more about density and buoyancy. I can make a living out if this program if I put all my effort in because they give out a lot of scholarships and for me to have a good future I need to get a few.

Minerals Among Us Venture outside on any particular day‚ look down along the traversed path and select a rock‚ any rock‚ call it Exhibit A. Observe it for a moment. How fantastic would it be‚ to positively identify it? To know that by observing certain properties of this rock‚ it can be said with confidence‚ that this particular rock has calcite‚ halite‚ mica‚ quartz or any specific mineral. Well‚ “because the atomic structure of a mineral species is always the same‚ most of its physical properties

these principles to overcome the force of gravity and achieve flight. Lighter-than-air craft‚ such as the hot air balloon‚ work on a buoyancy principle. They float on air much like rafts float on water. The density of a raft is less than that of water‚ so it floats. Although the density of water is constant‚ the density of air decreases with altitude. The density

The weight of an egg is distributed around the egg’s shell. The strength of an egg can be determined by testing the weight and pressure that an egg shell can absorb in the nature of the egg experiment. A raw or hardboiled egg can be used. The density of an egg will change depending on the experiment chosen. For instance when using vinegar in an
