This is just a notice that the timeline for the research project has been extended! Our first notebook checks will not be until next Thursday, March 27th. I will expect to see a full set up for your lab (introduction, objective, materials, procedure - all pages dated) and you should have taken data for at least a few of your trials. Final data collection should be done by the week before Spring Break. I will probably do final data checks on April 8th, and we will discuss the paper write-up on April 10th, before you leave for break.

Yikes, my apologies! I completely forgot to send out the key for the review sheet. Thanks to Aqsa for the reminder. :)
Some quick reminders of upcoming items!
1. Tomorrow will be a lab day, so please dress for it. We will discuss your homework (on molecular formulas) as well, and we may possibly introduce chapter 12 at the very end of class. 2. Tuesday will be quiz day for chapter 11. This will cover mole conversions (single and double step), molar mass, % composition, and empirical and molecular formulas. Need some practice? Try this review sheet! I will release the key over the weekend. We will start chapter 12 after the quiz. 3. Regarding your research projects: Please remember to refine your experimental designs and begin gathering materials and taking data. Again, keep in mind that you should be aiming for around 10 different trial types (iterations of your independent variable) and at least 5-10 trials of each. If a trial does not produce viable data, do not count it as a trial; refine your technique and try again (and remember to record everything!). 4. Your research project lab notebook should be separate from your in-class lab notebook. It should contain the same introductory information as a normal lab (table of contents, header, objective, materials, procedure, etc., to be updated/edited as necessary), but most of it will be data. Date every page. If you would like reassurance that lab notebooks do not need to be works of art, check out the lab notebook kept by Robert Millikan for his famous oil drop experiment. The important thing is that EVERYTHING is in the lab notebook, and that it is relatively legible and organized; nobody cares if it's a little messy or has a lot of cross-outs. Here is the key for today's pair of review sheets, and here is the link again for the Experimental Design form for the next step of the project. As always, if you have any questions, please stop by after school in room 206. My door is always open!
Next class, we will start with the lab, then take the test in the second half of class. That way, we can allow any finished copper samples to dry during the test, and if you finish early, you may take their masses before you go. We will discuss the analysis on Tuesday, and labs will be due by Thursday of next week (the 27th). The experimental design form will also be due on the 27th, and I will do my best to get them back to you as soon as possible so that you can start collecting data. Ladies and gentlemen! I have just been informed of a countywide decision that changes our whole schedule. Next week, Wednesday will be flipped from an A day to a B day, so the schedule will look like this: Monday: A day Tuesday: B day Wednesday: B day Thursday: B day Friday: A day So we suddenly have an extra day to play with! My thought is this: I'm guessing that at least a few of you could do with that in-class review for chapter 10 that we had to cancel, yes? What if we take tomorrow just to review and talk about the next phase of the research project, and push the test/2nd half of lab off to Friday? That way, we'll be behind the other classes temporarily, but we'll catch up again next week. I'm pretty sure I know what your answers will be, but humor me: take the poll below by clicking through to the website. Thanks to all of you who showed up at today's review session! Here is the key for that second review sheet (linked in the last email) - please take a few minutes to look at it and make sure you feel comfortable with the material, whether or not you showed up today. As always, I will gladly address a few last-minute questions before tomorrow's test - just keep in mind that we won't be able to spend a significant amount of time on review. See you all tomorrow!
Hi everyone,
Since we have missed yet another day of class and we still need to finish the lab, we will unfortunately not be able to fit in a review period before your chapter 10 test on Wednesday. If you feel that you would benefit from an in-person review session, drop by room 206 after school on Tuesday and I will be happy to answer any questions you may have! Here is the sheet that I was planning on using for our in-class review; I will post the key at the end of the day on Tuesday. On Wednesday, I will collect your annotated bibliographies, and briefly discuss the next stages of the project. Then we will test, then finish the lab. Enjoy the snow and the impromptu 5-day weekend! Mrs. Rosenberg Hello all! A quick note: we are changing plans for Thursday and Wednesday.
Since Thursday's class is likely to be too short for every group to finish their labs, I have decided that I would rather wait until we have enough time to do that. We will instead spend Thursday's class reviewing for the chapter 10 test, which is to be taken in the first half of class on Wednesday, the 19th. After the test, we will use the second half of class to complete the lab. In the event that we have a snow day on Thursday, I would be happy to host a group review session after school on Tuesday, but I will not be able to spend class time on review. If you would like a chance to review on your own before reviewing with me/the class, try the links on this review sheet. The test will cover parts of equations, writing formula equations from descriptions, balancing reactions, types of reactions, exothermic and endothermic reactions, predicting products, and net ionic equations. Hi everyone,
Before I go into the project stuff, allow me to summarize your homework and upcoming plans:
As mentioned in class, your next step in the research project is to conduct your background research. Spend the next week-ish looking up scholarly sources related to your project (or to the parts and materials thereof) and compose an annotated bibliography of the 8 best/most useful sources you come across. Please use APA style citations, according to this guide, or see the style guides at http://www.apastyle.org . The goal here is to narrow down your research question to a doable, properly formatted project, and ensure that your intended project is both safe and practical to investigate on your own. If you find that you need to change your topic or question, please feel free to do so! But your annotated bibliography (with 8 sources) must be turned in by February 19th. Looking ahead: Once you are finished with the annotated bibliography, the next step will be to design the experiment itself. You will fill out this form and submit it to me, and I will read through it closely and either approve your design or make comments that will need to be addressed prior to approval. Due to the snow day, the timeline for 2nd quarter grades has been pushed back. All 2nd quarter grades are now due on January 28th, and report cards will be distributed on February 3rd. Please check Aspen sometime this week to verify that all of your grades have been entered correctly.
