a. Define latent heat. Briefly distinguish between the latent heat of fusion and the latent heat of vaporization. b. Calculate the minimum amount of energy, in joules, required to completely melt 183 g of silver initially at 38.0°C. The melting point of silver is at 962°C.

Purpose:  The primary purpose of these summary reflections is to synthesize readings on the given topic. Another purpose of this assignment is to practice academic writing and APA. Thus, I expect you to use appropriate citation methods, headings, and formatting (though no title page nor abstract are required).  If needed, review the writing resources on writing a thesis, outlining, etc.).  Prompt:   You have been tasked with creating a professional development plan for your middle school to help fellow teachers better understand differentiation for middle level learners in the social studies classroom. Learners could be based on disability, gifted status, or language diversity (EL), but also based on student readiness, interest, and learning profile.    Provide an overview of a two-day professional development experience that addresses differentiation based on content, process, and/or product for learners in the middle level social studies classroom. Make sure to provide an overview of differentiation as a part of this PD. Assume that your peers are quite unclear about the topic. Then summarize the content/research base to support your peers in implementing best practices for differentiating in social studies/and or in general for at least 2 types of learners (gifted, disability, EL) with specific methods of doing so.  Resources: You can leverage strategies from classroom instruction that works as well, as well as your readings on differentiation.   Use the IRIS module from the weekly readings to help you with the general information related to differentiation.  This We Believe  Reminder, the following are topics to consider for preparing for your comprehensive exam: Differentiation1. With respect to adapting and differentiating instruction2. Within curriculum and program planning3. In terms of family involvement in school4. In terms of differences in achievement in each of the content areas Expectations/Format:   3-page minimum (4 page max) paper plus references.  Format:  1 inch margins, double-spaced, 11-point Calibri font. No cover page or headers are required (different from headings).  Review the attached rubric for criteria and other expectations.  APA – correct heading levels, in text citations, references. 

1.  Solve the following arithmetic problems.  Remember to show ALL work for this problem and and EVERY problem on this exam. a) Determine the unsigned hexadecimal, octal, binary, and BCD representations of the number 47310.  (I strongly recommend that you check your work before moving on to the next part of this problem.) Use scratch paper for this and ALL problems on this exam. Remember to show ALL work for this problem and EVERY  problem on this exam. Label each problem with the problem number, e.g., for this problem use  1. a) . Do NOT put ANYTHING in the box at the bottom of this problem (and similar boxes at the bottom of each of the problems). b)  Determine the 10-bit signed magnitude, 1’s complement, and 2’s complement representations of the decimal number -47310.  (I strongly recommend that you check your work before moving on to the next problem.) c)  What is 25610 minus 47310, i.e., 256 – 473 in 10-bit 2’s complement? You must use binary numbers to derive and determine the solution (not decimal).  Hint: 256 = 28. You must show all work. d) What is 48010 – 47310 in 10-bit 2’s complement? You must use binary numbers to derive and determine the solution (not decimal).  Hint: 480 = 28 + 27 + 26 + 25. You must show all work.
