All Bonus assignments will be due by the end of classes on Tuesday. The earlier in the week I receive your assignment, the more credit you get. Similarly, the better the quality of the assignment, the more likely you are to receive more credit.

If you complete an assignment comment to this post with your Name, Class, and Assignment.

Chemistry Class Bonus Opportunities:

Make a “Mind Map” Poster covering all the topics we have discussed this year. How to Make a Mind Map
Famous Scientist Video Interview - Research information about a famous scientist we have discussed in class this year. Use the information you have learned to create a video interview (minimum of 3 minutes of science). You should include details of the person's life, scientific accomplishments, and the affects their work had or has on society. Also, point out any further questions that their discoveries raise that may need to be addressed Example of a Famous Scientist Interview. Example #2
Careers in Science - Research a career in a scientific field that interests you. Education requirements and salary for a career in this field should be addressed. Sources may include reference books and internet sources. Sources must be sited. Write a 2-5 page paper explaining why you would or would not choose this career based on your research.
Chemistry Song Parody Music Video - Example 1, Example 2
Chemistry Game - Brainstorm and develop a game (board, card, etc.) that can be used to help students review chemistry topics. Write a set of instructions for the game, including how it should be played, the objective, and how a winner is determined. Make any game pieces necessary for sixteen people to play the game. Present the game to your instructor and "play" a game. E-mail the directions to your instructor and the Subject should include the student's Name, Class, Chemistry Game.. Example of Chemistry Board Game
Tutorial – Pick a topic covered in class earlier this year with which you struggled or excelled and create a tutorial video that I can put on the blog to help students in the future. Factual information should be included, but the majority of the presentation should focus on examples/solutions and applications of the topic.
Complete a Virtual Lab and associated activities:

Homework: (Due Monday after break)

Questions #21, 22, 25, 29 - 35 (p. 189)

Monday, November 22, 2010

In class:

Because of my absence on Friday, many classes received different assignments. In general, all classes reviewed electron configuration as well as introductory information regarding the formation of the periodic table.

Regardless of class, all students are responsible for having read all of Chapter 5 and completing the notes and questions associated with each section.

Homework:

The "Make Your Own Periodic Table" that students completed on Friday were returned. Each student is responsible for answering the questions below based on their periodic table.
1) What trends exist looking across the rows from left to right?
2) What trends exist looking at the columns from top to bottom?
3) What changes would you make to your table to increase the trends seen? What problems do you see where elements do not fit the trends? Analyze and Explain.
**The evaluation of this activity is more important than the creation of the table.**

WARNING: I STRONGLY encourage all students to review quantum numbers and electron configurations to prepare for a possible quiz later this week!

Flame Test Lab Report Due Friday (format below)

Name

Block

Date

Lab Partners: Partner 1, Partner 2

A very good title (What was manipulated? What was observed? What was studied?)

Purpose:

In a single paragraph write the purpose for this experiment. (Minimum of 5 sentences)

Data:

Put a title for your data table here.

HEADING	HEADING	HEADING

Questions:

1. Based on your observations from this lab, what is/are the unknown compound(s)? To receive full credit, you must justify your answer with a detailed explanation consisting of no less than 3 full sentences for each unknown. (Write your response below the data table you created)

Answer in bold font.

2. Is a flame test a qualitative or quantitative test for the identity of an unknown compound? Explain.

Answer in bold font.

3. If you look at the stars at night you will find that some stars are different colors than others. Stars release different amounts of energy during their lives. How might astronomers use line spectra to distinguish the ages of certain stars?

Answer in bold font.

4. Salts consist of a positive metal ion and an anion (an ion with a negative charge). An example would be NaCl – sodium metal (Na⁺) with a chloride anion (Cl^-). When doing this lab, do you think it is important to use salts with the same anions. Why or why not?

Answer in bold font.

5. When a glass rod is heated, a yellow-orange flame is observed around the point of heating. What does this yellow-orange flame indicate? Why is it observed when glass is heated?

Answer in bold font.

6. Use the Rydberg equation to calculate how much energy is necessary for an electron to occupy the n=1 shell of a hydrogen atom. (Give your answer in proper scientific notation with 3 significant figures.)

Do NOT type this answer. Write the answer in by hand.

7. Use the Rydberg equation to calculate how much energy is necessary for an electron to be excited from the n = 1 shell to the n = 2 shell of an atom. (Hint: ΔE = E_final- E_initial, Use your answer from above as the initial value for energy and use n=2 to calculate the final value for energy.)

Do NOT type this answer. Write the answer in by hand.
