Temperature (Celsius) of three different substances (Chloroform L2, Ethanol L3, and Acetic Acid L4) will be provided by your instructor. With this graph, answer the post-lab questions that pertain to Activity One. Activity Two: Given information about ammonia, recreate a phase diagram. The triple point of ammonia is 195.42 K and 0.05997 atm. The critical point is 405.38 K and 111.5 atm.

The structure of the lesson plans includes the objectives of the activities, the materials needed for implementation, the process of the activities and the timing of each single activity. The lesson plans proposed have been designed to be flexible and adaptable to the various European national contexts. The components of each lesson plan are detailed in the modules proposed in this guide. LESSON 1 Getting started, giving basic knowledge on chemistry and its applications: the teacher should show the video “Chemistry: All About You” to the students and then discuss briefly what they have learned.
Moreover, the solvent-free tosylation step of the reaction leads pedagogically to a discussion about green chemistry. KEYWORDS: Second-Year Undergraduate, Laboratory Instruction, Organic Chemistry, Hands-On Learning/Manipulatives, Alcohols, Aldehydes, Green Chemistry, NMR Spectroscopy, Thin Layer Chromatography, Synthesis Scheme 1. Synthesis of β-Citronellyl Tosylate I t has been a tradition in chemical education to use examples of compounds in “real-world” applications to illustrate esoteric concepts.1 Although many of the applications in textbooks and the chemical educational literature are biological and medicinal in nature, examples using soaps,2 essential oils, perfumes, and cosmetics can be traced back to the 1940s. There are several earlier articles published in this Journal that describe the chemical composition of essential oils,3 whereas more recent lab experiments focus on the synthesis of perfumes.4,5 Sulfonates of several compounds are used as additives in the perfume industry, especially for laundry and other cleaning detergents. One such sulfonate used as an additive to

Purity will be evaluated using melting point analysis. In Part B , you will esterify your newly generated salicylic acid usin g acetic anhydride to form acety lsalicylic acid, also known as a spirin. Again, purity will be determined via melting point. READING ASSIGNMENT: ● This handout for procedure .
What books are recommended that you should purchase for you course? My Tutor has recommended “Cite them Right” a referencing guide. As I progress through the modules then other books may be recommended. A basic Biology book is another recommended book. There are also more in the DLC Library.
Materials In the Materials section of your Lab Report, list the materials (everything) necessary to get this lab done. C. Procedure The Procedure section of your Lab Report lists instructions or directions needed to accomplish the lab. They are already listed on the paper and do not need to be repeated. D. Data In the Data section of your Lab Report, you will be recording “just the facts” you’ve observed in your experiment. Data may include tabulated numbers, graphs, and short explanations of observations.
Investigating the effect of pH on amylase activity This practical allows you to: • discover how pH affects the rate of an enzyme controlled reaction • evaluate the experimental procedure Procedure SAFETY: Follow your teacher’s instructions for handling the solutions. Wear eye protection when handling the iodine solution. Investigation a Place single drops of iodine solution in rows on the tile. b Label a test tube with the pH to be tested. c Use the syringe to place 2 cm3 of amylase into the test tube.
Historical Philosophy Report Ryan Hart 1/29/14 Philosophy: System of gymnastics that included “light gymnastics” and focused on developing his students minds and bodies through the blending of comparative anatomy (anthropometry), physiology, hygiene, and religious beliefs. Philosopher: Edward Hitchcock Background on Philosopher: Edward Hitchcock was hired as the professor of Hygiene and Physical Education at Amherst College in 1861 (Leigh, 1982, p. 19). He had previously taught elocution and natural science at Williston Seminary (Brunner, 1982, p. 22), he had a liberal arts education, held a medical degree from Harvard, and had studied anatomy, physiology, medicine, and anthropology in London and Paris (Leigh, 1982, p. 20). In regards to choosing “light gymnastics” for his curriculum, Hitchcock was influenced by Catherine Beecher and Dio Lewis two pioneers of physical education (Leigh, 1982, p. 20). He was also greatly influenced by his father and his Christian faith, which led him to strongly believe in the unity of mind and body, and become “...a man with a vivid sense of the dignity and nobility, piety and grace, strength and beauty manifested in God's finest creation: the healthy, upright, well-cared-for human body (Brunner, 1982, p. 22).” Hitchcock's background in science and love of comparative anatomy led him to use the new science of anthropometry which was developed and applied for the first time in the 1830s and 40s (Leigh, 1982, p. 21).
BTEC Nationals Edexcel level 3 BTEC National Certificate/Diploma Applied Science (Laboratory and Industrial Science) Applied Science (Medical Science) Integrated Vocational Assignment CASE STUDY 2- Johnson Matthey (Catalysts and Chemicals) Unit 3: Workplace practices This case study has been prepared by Mr. M. Hooper & Ms P. Hooper with the co-operation of Johnson Matthey (Catalysts and Chemicals) for the use of learners completing the IVA for the NQF Level 3 BTEC Nationals in Applied Science. Prepared by M. Hooper & P. Hooper. March 2005 The following materials have been authorised for use by students in this context, by Johnson Matthey. Some data is not current, and some is adapted to give a working document to allow completion of the assignment, To complete the assignment students must have access to detailed information about a company. This is often difficult to obtain, and the following information will provide exemplar material for the completion of the IVA.
*Engage in kinesthetic activities. (Dean, Hubbell, Pitler, and Stone 2012 ) Now the questions might be asked: Have you used nonlinguistic strategies in your classroom? Can you share these experiences? I think we will benefit from each other experiences since they are coming from the field. Here are some tips for teaching using nonlinguistic representations I found in the book classroom Instruction that Works: 1.
