Sections 4 & 5: Read this article: Nuclear Fusion and be sure the check out the ITER Tokamak mentioned (here's a link to it). Then, in your notebook, write down two reactions to the article and at least one follow up question you have. 

Extra Credit Opportunity! (Due Thursday)

Watch the video from the link below. Then, answer these questions:

1. Why is element 114 so important? What would it help us to learn about chemistry?

2. Why do you think we skip right over element 113? What makes 114 a more practical goal?

3. What did Glen Seaborg mean by the Sea of Instability?

4. Why didn’t Seaborg’s method work to create elements beyond number 102?

5. What do they mean by “bowling elements”? Which elements did they use in this method and why? 

6. Has element 114 been found since this video was made? If so, by whom? Does it have the properties the video predicted it would have?

**All work must be typed, TNR, 12pt font.**

Section 5: Write an essay on the pros and cons of nuclear power (based on nuclear fission), paying particular attention to its effects on global warming, nuclear reactor safety, weapon risks and nuclear waste disposal. Essays should be 1-2 pages in length and must include citations and a works cited section. Due Tuesday.

Section 2H: Write an essay on the pros and cons of nuclear power (based on nuclear fission), paying particular attention to its effects on global warming, nuclear reactor safety, weapon risks and nuclear waste disposal. Your essay must also include at least one paragraph on how you think New York state should be sourcing its energy over the next 10 years (i.e should we switch to solar, wind farming, more nulear, a combination, etc). Essays should be 2-3 pages in length and must include citations and a works cited section. Due Tuesday.

Essays should be 1-2 pages in length and must include citations and a works cited section. Due Monday.

Section 5: Complete half life problems 3&4 in the packet on pg. 6 (we did 1&2 together already) and the half life worksheet given out in class today.

Tuesday, October 20

Section 4: Complete the back page of your nuclear chem packet (if you have not already) and the half life worksheet given out at the end of class.

Section 2H: Complete page 8 of your packet (if you have not already), half life problems 3&4 in the packet (we did 1&2 together already) and the half life worksheet given out in class today.

Monday, October 19

All: Complete your lab packet. For extra credit:
You can create the graph from the back page of the lab digitally (on excel, logger pro, etc). Once you've plotted all your points, use the curve fit option 'natural exponent'. You may need to mess around with some of the line fitting options to get the best fit. Once you've done that, trace the curve and mark the point that best expresses the half-life of our sugar cubes. A box should pop up that represents all the info from that data point - make sure that's included on your graph. Print the graph and the data set and attach it to your lab.

Section 5: You should also complete the back page of the nuclear decay packet that we started in class today.

Sections 2H & 5: Make a graph of the information you gathered by organizing the cards in today's activity. Don't forget, your x-axis should be atomic number and your y-axis should be atomic mass. Use as much of the graph space as possible but don't go over the edge and create new lines! Here's how the first few plot points should look:

Section 2H: Watch and take notes on this video: Intro to Nuclear Chem
Use the info in the video to compete the back of the worksheet we started in class.

Section 5: Complete the worksheet you got in class today. Use this video to help you:
Intro to Nuclear Chem (take notes on it if you didn't already in class or think your notes could use some padding).

Use the info in the video to compete the back of the worksheet we started in class.

Tuesday, October 6

Sections 4 & 2H: Read chapter 21, section 1 of your textbook. Then answer the section 1 review questions (all) in your notebook/binder.

Monday, October 5

Section 5: Complete your adopt and element project by Thursday! If you make a website, email it to me before class on Thursday. Posters of all sizes welcome!

Friday, October 2

Sections 2H & 4: Complete your adopt and element project by Tuesday! If you make a website, email it to me before class on Tuesday. Posters of all sizes welcome!

Kairos Students: Welcome back! Complete the section 5 homeworks posted from Monday and Tuesday. Also, if you are in sections 2H or 4 please come see me on Monday to get caught up about a project. If you cannot make it during CP, send me an email with your availability. If you are in sections 2H or 4 and want to get a jump start on your project, the information can be found under homework documents. This is NOT required, as you will have extra time to complete the project.

Section 2H: Tonight you're going to mess around with a simulation of Rutherford's gold foil experiment. The link to the simulation is below (you may have to allow pop-ups for it to work):
http://phet.colorado.edu/en/simulation/rutherford-scattering

There are two tabs (Rutherford and Plum Pudding), as well as several settings (energy, number of protons, etc). For each tab you will play around with the settings and make some observations. Remember that you can only draw accurate conclusions if you change only one variable at a time. For each tab, fill out a chart in your notebook that looks like this (you should have at least 3 rows of observations for each):

Variable changed	Observation	Possible explanation of the result

Section 5: On Monday, you will 'adopt an element'. You will begin a project on one element from the periodic table. Your homework for tonight is to start doing some light research. Look up some information about elements that interest you from the periodic table (where they're found in nature, what they're used for, etc) and email me you top 3 choices in order. Consider choosing a less known/common element!

All: We will be meeting in the LC for lab tomorrow and Monday!
