Tuesday October 30 – Review organization of periodic table and properties of metals. Zinc Plating Lab.
Friday Oct 26 – Starting periodicity (Chapter 3). Create videos discussing organization of the periodic table. My video
Wed Oct 24 – Exam. HW: Notes over 3.1
Mon Oct 22 -Penny lab had unnexpected results AGAIN! What is going on here? A second penny was dropped into the blue HCl solution containing the already dissolved penny and…voila. HW: Review for chapter 2
Wed Oct 17 – Penny lab did NOT turn out as expected. Pennies were completely dissolved. Discussed activity series of metals. Started penny lab again.
Thurs Oct 11 – Review atomic structure, atoms, ions, isotopes. Last class we learned that pennies have two “isotopes.” One of the isotopes has a lighter mass because it has a zinc core. To prove that this is correct, we will dissolve the zinc core with acid. Zn + HCl –> ZnCl + H2
Tuesday Oct 9 -Dry Ice experimentation. Penny Isotopes lab activity. Atoms, Ions & Isotopes practice quiz.
Friday Oct – 5 Atoms, Isotopes & Ions practice.
Wed Oct 3 –
Monday October 1 – Turn in notes for chapter 2. Class activity: building atoms with paper chips. Atoms are made of protons, neutrons and electrons. Atoms must be NEUTRAL. Ions are charged. Isotopes are “flavors” of atoms that depend on the number of neutrons. The number of PROTONS determines what kind of atom it is.
Thursday Sept 27 – Mark is out. Sub present. Students have a few measurements to take in the lab to wrap up the “separation of sand and salt” lab. They should then finalize their written results and turn in. If labs were not turned in at the end of the period they are 10% off for being late.
After this students worked on Atoms & Atomic Structure worksheets. Print off the Atoms ppt with 4 or 6 slides per page for students to read. They can use this as they go through the worksheets.
Tuesday Sept 25 – Review. Chapter 1 Exam. HW: notes for Chapter 2. Video assignment: Please go to “goanimate.com” and sign up for a free account. This will allow you to make videos for free using online software. No download required. You will not be able to publish to youtube without paying a fee but, you can share links of your videos with the free account.
Friday Sept 21 -Finish separations lab. Get ready for exam next class.
Wed Sept 19 -Boiled off water for separations challenge. As boiling went on we went through the following: section review on page 33, section review on page 44, Chapter 1 assessment on page 46-48, Standardized Test Practice on page 49.
Monday Sept 17 – Handed back quiz & students had a chance to make corrections. Started “Separations Challenge” in lab. Most students go to the first filtering stage by end of class.
Thursday Sept 13 –
- Play video: Beautiful Elements http://www.youtube.com/watch?v=h4XIOpKWc1Y&feature=relmfu
- Play video: Most Dangerous Chemicals http://www.youtube.com/watch?v=u6MfZbCvPCw
- Students take notes from textbook & turn in
- Chapter 1 pages 28-33
- Chapter 1 pages 34 – 44
- Quiz
- Reactions of potassium http://www.youtube.com/watch?v=pPdevJTGAYY&feature=relmfu
- When done, students may work on research project.
Monday Sept 10 – Reviewed the requirements for lab notebook. Students then re-wrote the Salt Water / Fresh Water Density lab. Continued with separations techniques. Next class will be a quiz.
Thursday Sept 6 – Reviewed classifying matter packet. Discussed types of separation techniques and principles on which they are based. Started lab activity on separations. We will continue this activity next class.
Tuesday Sept 4 – Density quiz. Turn in Chapter 1 notes (p14 – 27). Discussion: types of pipettes. Lab activity: pipetting for accuracy. HW: classifying matter packet (due NEXT class).
Thursday Aug 30 – Fake Pop Quiz on density. Kitchen Chemicals lab. Completed lab in this class period. Talked about how to write up lab in notebook. Notebooks are due next Tuesday (Monday is a day off). Quiz next class on density & other basic information we have covered so far.
Tuesday Aug 28 – Review density. In class assignment: density worksheet. Density worksheet answer key is here. Lab: finish density lab. Review key concepts: density = mass / volume, 1 cubic centimeter = 1mL, volume can be found by calculating or by water displacement, don’t forget to account for the mass of your container. HW: Reading Chapter 1 (p14 – 27).
Friday Aug 24 – Students showed videos they found online showing chemistry demonstrations / experiments. Discussed what was happening and safety procedures that were or were/not followed. Density Lab: solids, liquids. Part 3 will be completed Tuesday. HW: Home-Lab – Design and conduct experiment using cornstarch & water. Might be useful to look up terms like “oobleck” or “non-newtonian fluid”
Wed Aug 22 – Several Videos were shown highlighting safety, terminology, and applications of chemistry.
Monday Aug 20 – Logistics: Course objectives, where to hand in assignments. Review lab safety, map of the lab (safety features, safety concerns). Observation of reactions. Name & describe reactants, predict products, describe result. Safety concerns with each reaction. HW: find an interesting chemistry demo on youtube, prepare a description of experiment & analysis of safety concerns.
Wed Aug 15 – Review of schedules. Intro to applied chem. List 3 safety rules and 3 things you would like to do / learn in chemistry. Homework: safety contracts, video permission form.
