11/24/09 Alpha & Beta Radiation and Nuclear equations


Tests were returned. There is a makeup test available for the test we took on 11/20. To sign up you need to log onto the castlelearning.com website. Students may go there to review for tests and as study guides. Students will have to log in with "averillpark.studentid" where studentid is their id number in 9 digit format, with leading zeros, if needed. The first time students log in they will be prompted to set up a password. Follow the instructions to enter a password.

You have until Wednesday 12/2 to complete the makeup test. If you get an 80% or higher, on the combined two parts, I will average the makeup and your original test for a grade. If you do not get at least 80% your original test score will stand.

If you have difficulty logging on or any other difficulties you can email me at aphsbio at gmail.com.

11/19/09

This week we talked about atomic structure. Specifically, we discussed Lewis dot diagrams, electron energy levels, orbitals, ground and excited states, the EM spectrum and properties of waves.

I collected the Spectroscopy lab report.
We did the Flame Test lab. The report is due on Friday, 11/20.

We will have a test on Friday, 11/20.

Coming up
  • We will do the Flame test lab.
  • We will continue the Nucleus unit. The material from this unit will not be on the test this Friday.
Homework:
  • The Flame Test lab report is due on Wednesday, 11/18.
  • Study for the test.

Students need to complete one project each month. The current project is the first of two choices. If both are completed, it will count as extra credit. Click here to see the project.
Note pages from the complete PowerPoint can be found here: 2 slides per page in color or 6 slides per page in black & white.

11/17/09 The nucleus


This week we talked about atomic structure. Specifically, we discussed Lewis dot diagrams, electron energy levels, orbitals, ground and excited states, the EM spectrum and properties of waves.

The Rutherford's experiment and the Isotopes of Kandium lab reports were collected.

We did the Spectroscopy lab. This report is due on Wednesday, 11/18.

We will have a test on Friday, 11/20.


Coming up
  • We will do the Flame test lab.
  • We will begin the Nucleus unit. The material from this unit will not be on the test this Friday.

Info from the page of the graphic for this entry: The atomic nucleus consists of nucleons—protons and neutrons. Protons and neutrons are made of quarks and held together by the strong force generated by gluon exchange between quarks. In nuclei with many nucleons, the effective strong forces may be described by the exchange of mesons (particles composed of quark-antiquark pairs). A proton consists of two up quarks and one down quark along with short-lived constituents of the strong force field. A neutron is similar except that it has two down quarks and one up quark. Although scientists are convinced that nucleons are composed of quarks, a single quark has never been isolated experimentally. Energy brought into a nucleus to try to separate quarks increases the force between them. At high enough energy, the addition of energy creates new particles rather than freeing the quarks.

11/13/09 Atomic structure


This week we talked about atomic structure. Specifically, we discussed Lewis dot diagrams, electron energy levels, orbitals, ground and excited states, the EM spectrum and properties of waves.

On Thursday we did two labs. The first was Rutherford's experiment and the second was Isotopes of Kandium. Both lab reports are due Monday.

We will have a test on Friday, 11/20.


Coming up we will have the Flame test and Spectroscopy labs.

11/4/09 Explore Castlelearning


Test: We will have a test on Thursday, 11/5. This will primarily be on material from the Matter & Energy unit.

I have set up classes for the castlelearning.com website. Students may go there to review for tests and as study guides. Students will have to log in with "averillpark.studentid" where studentid is their id number in 9 digit format, with leading zeros, if needed. The first time students log in they will be prompted to set up a password. I have set up a review test.

Today we:
  • Continued with notes from the unit on atomic structure.
  • Dis some stoichiometry practice questions and handed out a worksheet.
  • Collected the elements and ions lab reports.
Coming up:
  • Continue with the notes on Atomic structure.
  • More practice stoichiometry problems.
Homework:
  • Review the notes.
  • Study for the test.


Students need to complete one project each month. The current project is the second of two choices. If both are completed, it will count as extra credit. If you weren't one of the six students that did the last project, you need to complete this one. Click here to see the project.
