Lesson Plan Using the ASSURE Model in Social Studies Overview: Students will create a podcasting using a Siskel and Ebert Format after reading a novel in class. A – Analyze learners The students in this particular social studies class are either on or just above their reading level. Also‚ most of the students were of other social classes and ethnic backgrounds. Another positive characteristic is that that the majority of the students in the class were familiar with various kinds

BASIC CHARACTERISTICS OF EXCELLENT PROGRAMS In order to gather the "right" metrics about a referral program‚ you need to know upfront what the critical design elements are that turn good referral programs into great ones. Next‚ you need to have metrics that cover each of these critical areas if you expect to continually improve your results: * ON-THE-JOB PERFORMANCE. The primary reason for using referrals is because they produce better performers (quality of hire). Metrics must be developed to

The Purity and Purification of Solids Melting Points CH-337 Abstract: The purpose of this experiment was to find the eutectic point for the mixture of naphthalene and biphenyl. This was done by measuring the melting point of both pure substances and five mixtures of different ratios. The purpose of the second section was to identify an unknown sample by measuring its melting point and mixing it with two known substances and comparing them. The results suggest that the eutectic point is closest

Experiment 1 Separation of Mixtures Summary of Principles: Most of the materials we encounter in everyday life are not pure substances. Many materials such as sand are formed from physical combination of various substances‚ and are called mixtures. Mixtures can be classified into homogeneous and heterogeneous. The purpose of this lab is to learn how to separate individual components from a mixture through decantation‚ filtration‚ distillation‚ and crystallization. Pre-Lab Questions: Attached

Lab 3 – Separation of a Mixture of Solids Cathy Lab Partners: Chelsea Brooke Sept 4‚ 2012 Chemistry 131A Dr. Vicki H Audia Pelab Questions: Proposed procedure for separation of a mixture: Use physical properties of the 4 substances to separate. 1. Remove iron with magnet 2. Add water to the mixture to melt the benzoic acid and NaCl then filter out sand. 3. Chill the solution and scoop the acid out leaving a salt solution. 4. Boil water away leaving salt. Purpose: The

Note about problem set 1. Because this is the first problem set and because it’s the introduction to formal logic‚ many questions on this set are of the form “write down an x equivalent to y.” There’s no intermediate work in such a problem—one simply writes the answer down and moves on. This is generally not the case

Experiment 2: Separation of a Mixture of Solids Purpose: This experiment allowed me to learn different separation techniques for various substances based on their specific chemical properties. Procedure: I began this experiment by using a magnet to pick up and collect the iron filings out of the mixture. Then the sand was separated by placing the mixture into a beaker and boiling it in distilled water in order to dissolve the salt and benzoic acid‚ once boiling the liquid was poured out leaving

Discussion of this experiment began with discussing how many materials we use today are actually mixtures of pure substances. The separation of these materials into their pure substances can be quite challenging. When we are discussing separations of a mixture that contains pure substances‚ it all depends on whether you can separate the substances by physical means. That means‚ utilizing each substances physical properties such as boiling point‚ melting point‚ and magnetism. Separation of a Mixture of

PURPOSE The purpose of this experiment is to become familiar with the separation of mixtures of solid and learn separation techniques based on the chemical properties of a substance. PROCEDURES 1. Separating out the Iron a. Use your digital scale to determine the mass of your weighing dish. b. Empty the entire mixture of solids from the plastic bag into the weighing dish and determine the gross mass of the total mixture and weighing dish. Compute the net mass of the mixture: this is equal
