Sections 8, 9 & 11: Based on your reading (found to the left) and today's video, answer the following questions:
2) Which of the aforementioned parties do you think have the loudest voice?
3) Is there a way for the scientific community to remain patriotic and pacifistic?
Be prepared to debate your answers next week.

Section 8: Today, we started out 'lab' by added 15mL of 1.0 M HCl to a flask. Then we added 75 mL of water.
After this dilution, what is the new molarity of the HCl solution?
If we used 150 mL of NaOH to reach the endpoint, what was the molarity of the NaOH solution?
Now that you have those numbers, I want you to think about the question I asked you today in class, did the addition of the water effect the outcome of the titration?
Section 9: Complete the worksheet I handed you in class today. Be prompt for class tomorrow.
Sections 8, 10 and 11: Tomorrow you should come straight to the commons during our class period. I will be near the 1L entrance. Make sure you come straight to find me so I can take attendance and hand you the worksheet you will be doing while at the science fair. DO NOT BE LATE.
**If you are taking a make-up quiz tomorrow meet me in 3K2.

The answer keys to your practice pages can be found under homework docs. **pH key 3 is for section 10 only!**
I will be in 3K2 at 7:45 tomorrow if you have questions.
You will NOT be getting equations on the quiz!

Section 8: We started today's video at 16:00 (can be found below). Reading will be up tomorrow, you should use it to add to your note taking sheet.
The Disappearing Spoon
Section 9: Answer the following questions:
1) How are the various ways we think water formed on early Earth?
2) Describe the theory of water delivery by comet to early Earth.
3) What are the flaws in this theory? Explain and give proof.
4) Look up "heavy water" and give a brief description of it.
5) What are some current and historical uses of heavy water?

Section 10: Answer the following questions:
1) How did Newton picture space?
2) Describe Newtonian space and its interactions with the objects in it.
3) How would Newton explain the skaters arms splaying out as she spins?
4) What is special about the speed of light?
http://www.pbs.org/wgbh/nova/physics/fabric-of-cosmos.html#fabric-space
Section 11: Don't forget to send me your data!
Also, look up the difference between distilled and deionized water and write a short explanation in your notebook. Then, explain how/if you think the experiment would have changed if we used distilled, deionized or tap water.
Finally, think about this:
What was the composition of your solution when it reached its endpoint? What types of ions were in there? Was it acidic? Basic? Neutral?

Thursday, April 18
All: When completing your SFP paper keep the following in mind:
- You need to include EVERY part of the project. If you lost the packet I gave out at the beginning of the year, you can find it below under Homework Documents.
- Bullet points are not acceptable, except if you want to do a step-wise procedure section.
- Data tables and graphs should have TITLES, AXIS LABELS AND DESCRIPTIONS.
- I cannot seem to stress this enough, DATA TABLES SHOULD BE INTEGRATED INTO YOUR DISCUSSION.
- You must have an abstract (very short - 200 words)
- Include pictures! (label them as 'Figure 1.', 'Figure 2.', etc.
- IF THERE ARE NOT APPROPRIATE CITATIONS IN YOUR PAPER, YOU WILL RECEIVE A ZERO. THIS IS NOT UP FOR DISCUSSION.
- Your conclusion can include how you would modify the experiment to improve it in the future.
Wednesday, April 17
All Sections: Complete the neutralization reactions worksheet (you either received it in class or can find it at the bottom of the webpage under homework docs).
**Final drafts should include ALL parts of your project. Due date has been moved to Friday at 4pm (hard copy or email).
