Compound IV. Procedure- Experiment 1- Combine a few iron filings along with sulfur powder on an unused piece of paper. Mix the samples well with a scoopula. Examine the mixture with a magnifying glass and record your observation. Next‚ move the magnet under the mixture and reexamine it with a magnifying glass once again and record the observations. Discard the sample. Experiment 2- Fill a small

Research Activity Constructivism and Student Misconceptions: Why Every Teacher Needs to Know About Them The article I chose to do this research activity on was "Constructivism and Student Misconceptions: Why Every Teacher Needs to Know About Them" by Audrey Sewell (Appendix A). I believe this article addresses a key idea that all teachers should be aware of‚ student misconceptions. For this paper I will start by summarizing the key ideas‚ then I will go on to discuss how they relate to the

MODELING OF ELECTRIC MACHINES FOR AUTOMOTIVE APPLICATIONS USING EFFICIENCY MAPS S. M. Lukic and A. Emado Illinois Institute of Technology Abstract: In most industrial applications of motor drives‚ motors operate at one or a few predefued operating points. However in propulsion applications‚ the motor is used over the entire torqudspeed range. Therefore‚ the motor has to be studied at all possible torqudspeed combinations within the motor operating envelope. Efficiency maps are a convenient way

English 1B Essay Five: The End of the World as we know It III How do You Envision the End? We have examined two end-of-the-world scenarios: global climate change and the moral and economic collapse of America. But don’t worry: there are plenty more! What is your take on the topic? Essay Five asks you to respond to the following issues: What apocalyptic scenario do you envision on our horizon? Why do you envision that one rather than another possible one? Or‚ if you don’t see any dangers

Lanthanum is expected to drive the market over the next six years. These metal catalysts find applications across a host of industries including automobiles‚ metallurgy‚ phosphors and glass among others. In addition‚ growing market for permanent magnets is expected to particularly boost the demand for Neodymium. Certain rare earth elements such as terbium‚ europium and yttrium find applications in the phosphor industry. Phosphor is a vital component in the manufacturing of LCD screens and CRT

DIFFERENCES BETWEEN ASSOCIATE DEGREE NURSE AND BACCALAUREATE DEGREE NURSE There are several benefits of having a baccalaureate-degree (BSN) over the associate’s degree (ADN). In this essay‚ I will discuss how effective communication can be further developed when obtaining the BSN. Next‚ I will talk about how a BSN can create a more highly qualified nursing workforce. Lastly‚ it will be explained that getting a BSN will create better career and higher education opportunities. EFFECTIVE COMMUNICATION

SUPER CONDUCTORS Superconductivity is an electrical resistance[->0] of exactly zero which occurs in certain materials[->1]below a characteristic temperature[->2]. It was discovered by Heike Kamerlingh Onnes[->3] in 1911. Likeferromagnetism[->4] and atomic spectral lines[->5]‚ superconductivity is a quantum mechanical[->6]phenomenon. It is also characterized by a phenomenon called the Meissner effect[->7]‚ the ejection of any sufficiently weak magnetic field from the interior of the superconductor

Using the strong word “magnet” and capitalizing the “P” in “Personality”‚ Whitman argues further that great character is needed for a student to be the center of a crowd as opposed to a shadow following others. Whitman states that if a student has such qualities‚ “has such a body and soul… when you enter the crowd an atmosphere of desire and command enters with you‚ and every one is impress’d with your Personality” (Whitman). He tells students to become like a “magnet”‚ to attract others to with
