ATTENTION: If you have not already done so, locate three (3) shiny United States pennies that were minted after 1982, the shinier the better, to experiment with. Bring these pennies in to transform two of them into souvenir alloys celebrating your taking chemistry this year! The pennies will be treated to form souvenirs of chemistry class. If the pennies you bring in are dull, you will have the clean them. Store them temporarily in your grommeted, three hole zipper pen case until it is time to do the laboratory activity.
Start the following in class:
1. Go to the web site at http://www.visionlearning.com/reg/login.php, log on into the course+section for which you are registered, and select the module entitled Chemical Bonding. Read this module as if you were creating an SQ5R or PQ5R study guide for it, but are title it: In Class: Chemical Bonding. Click here to read the full instructions for what you need to do. When you are finished, click on the Questions > Quizzes tab at the top of the module and then click on the Chemical Bonding title, select the best choice response to all the quiz questions and then click on the Score Quiz button. Then examine the feedback on your quiz and reread and study the material pertaining to any items identified as incorrect. Reflect on your responses and retake the quiz as many times as you need for you to fully understand and from that understanding, score well on the quiz.
2. In your Journal Notebook write your journal entry on sheets of three holed 8.5 inch by 11 inch ruled paper. In the upper right corner white space of each upward facing page, use a blue or black pen to write your hand in number within a circle followed by your name. To the left of the marginal line, print J57 and circle it. Each journal entry should either be at least a paragraph of exemplary writing and penmanship concerning a single topic, or be a concept map relating chemistry terms. Begin each day’s paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement. The required journal focus questions J57 for today are:
a. How are ionically bonded compounds and covalent molecular substances alike? [Hint: Base your response on what you learned were the differences between ionic and covalent bonding when you read and took notes on the Visionlearning module on Chemical Bonding.]
b. Give an example of how ionically bonded compounds and covalent molecular substances are alike.
c. How are ionically bonded compounds and covalent molecular substances different? [Hint: Base your response on what you learned were the differences between ionic and covalent bonding when you read and took notes on the Visionlearning module on Chemical Bonding.]
d. Give an example of how ionically bonded compounds and covalent molecular substances are different.
3. If you have not yet finished it in class, finish doing the Section Reviews 7.1, 7.2, and 7.3 in the packet for chapter 7 as a formative assessment to find out some of the things that you do and do not know, and not as a research project.
- If you did not obtain a section review packet for the chapter in class, go to MNSD Google Drive > Student Resources > Section Reviews and print off a section review for each individual section of the chapter.
- The section review packet for each chapter contains a separate section review document for each section of the chapter. So for example, a chapter with four sections would have four separate section review documents that need to be printed off. Each section review question document is identified by a name whose last two digits or last three digits represent the chapter number followed by the section number of that particular section.
- For each question or problem challenge, either answer the question to the best of your ability using one or more full sentences, or answer the problem to the best of your ability by recording any numbers and units together with the mathematical operations performed in symbolic terms, along with the solution to the problem which should be circled.
- This is an important assignment. Be sure to finish this packet in its entirety.
- After doing the section review packet, but before you demonstrate your understanding on our class’ chapter test, you will check all your responses using green ink check marks √ for each correct response, and by lining out (striking trough) and inserting improved text in green ink when you think the suggested response expresses your present understanding in a better way. Then, when you know what you didn’t understand, you will be able to study more efficiently by studying that which you have corrected in green ink.
4. Locate the “Writing the Formulas of Ionic Compounds Correctly” worksheet, on page 7 of the Ionic and Metallic Bonding packet and write the correctly written formulas for five more rows of cation compounds according to the instructions given for LARN 055.
Recommended for those who have time left in their 45 minute study period, but not required of all:
1. In the ionic bonding informational packet, turn to the last page (page 24) and fill in just the Metallic Bonding column on the worksheet entitled “Property to be understood” using blue or black ink.
Think about the sixteen properties of metallic compounds listed. Relate each property of an metallically bonded substance to its positive and negative ions attracting each other strongly in all directions. In your Learning Log record any question(s) you would want to ask your teacher in class about the above mentioned properties.
