Today’s experience at my site-base was much different than on Monday. I came at the very beginning of the school day, so that I could observe the procedures that Mrs. Wright uses when the students arrive to school. Furthermore, I was able to participate more frequently during this observation than the previous one, which I appreciated because I was able to get to know the students better. One aspect of today’s class that I felt worked really well was Mrs. Wright’s morning routine. She welcomes

Results and discussion 4.1. Polymerization mechanism In base catalyzed aldol condensation of cyclohexanone (A), KOH or NaOH acts as a non–nucleophilic agent. In presence of base, cyclohexanone initially turns to enolate by losing αhydrogen. The formed enolate then reacts with the carbonyl group of the second molecule and leads to the formation of aldol intermediate. The polymerization reaction proceeds further by the reaction between the carbonyl group of third molecule and the activated methylene

25% water and 75% cornstarch mixture will create the non-Newtonian fluid with the highest level of viscosity because the mixture is made of particles of cornstarch suspended in water, therefore, the more particles there are, the harder it will be to shear the fluid. Data that was measured from this experiment supports the stated hypothesis. Trial one provided insight to the experiment. For the control, the marble took 0.4 seconds to drop from the pen ramp and into the water. The red composition (75%

The Eye of a Tornado In the article “What is it like in the eye of a tornado?” by Charles Bryant, the reader learns about the center of a tornado. According to the American Meteorological Society, a tornado is a “violent rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud.” Even though a tornado is extremely dangerous, there are two people who have entered the eye and made

Cause and effect of Tornadoes By: Jazzmin Aldrich Specific Purpose: To inform the audience more about tornadoes Thesis Statement: Understanding what causes tornadoes, knowing when and where they are going to occur, and remembering safety rules can make their life much easier. Introduction: I. (Attention Getter) A very common description by people who have seen it is that it resembles the trunk of a huge elephant as it weaves back and forth across its path. It sucks up

MM4TTF: Introduction to Turbulence and Turbulent Flows Case Study 1: Turbulent Boundary Layer Structure Turbulent coherent structures are flow patterns that can be distinguished from each other, as opposed to motions such as eddies which are subject to the phenomenon of superpositioning. Several of these occur in the near-wall region: ‘Low speed streaks’ refer to the regions of relatively slow flow spaced out in a pronounced manner. They generally occur ‘between the legs of hairpin vortices, where

In the specimens, all showed a brittle fracture due to how the stress vs strain slope looked and where the Ultimate Tensile Strength was located. Also, how the composited specimens failed look consistent that there were any defects in the specimens. The 0°/90° carbon/epoxy specimen failed in the longitudinal direction because of how the fibers were aligned in that direction. The

elastic. Tensile strength and modulus are orders of magnitude smaller than those of metals and elongation is 1000 % that of metals in a few cases. The tensile strength is defined at the fracture point and can be lower than the yield strength. Mechanical properties change dramatically with temperature, going from glass-like brittle behavior at low temperatures to a rubber-like behavior at high temperatures. Decreasing the strain rate has the same influence on the strain-strength characteristics as
