Science / Tech Competition
On March 2, 2013, the Central Western Section of the Science Teachers Association of NYS will sponsor the thirty sixth annual Science Congress at St. John Fisher College. Students (grades 6-12) from the region represented by Central Western Section present their research projects to scientists and educators who judge their understanding, research methods, and ability to communicate. Many student projects are recognized with awards, such as Honorable Mention, Honors, High Honors, and Highest Honors. In addition, special awards are presented by organizations for exceptional work in particular subjects. The highest reward is to be chosen to present at the STANYS State Science Congress or at the prestigious Intel International Science and Engineering Fair (ISEF)*. Some participants may be eligible to participate in a special middle school program entitled Broadcom MASTERS * (a competition in Math, Applied Science, Technology and Energy for Rising Stars). It is a joint effort of Broadcom and the Society for Science and the Public (SSP). The ISEF and Broadcom MASTERS opportunities offer our students horizon broadening experiences at the national level. It is only through the support of area businesses, local professional organizations, St. John Fisher College, the military, scientists, teachers, and other individuals, that Central Western Section is able to hold a Science Congress and to make these unique opportunities possible.
* Funding for 2013 has not been assured to enable STANYS-CWS to participate in these national and international programs.
The Science Congress Committee is composed of members from education and industry. Some people volunteer their time to find judges, mentors, sources of awards, and donations. Other volunteers register the students, make educational connections, or review student work for conformity to ISEF regulations. If you are interested in being a member of the Committee, a judge, or have ideas about sources of donations, please contact Director Dr. Jutta Dudley (juttasd@aol.com) or Co-Director Sheila Root (sroot@sjfc.edu).
No such thing as “No Gravity”
A great clip from Al Worden, command module pilot for Apollo 15. Entire interview is good, but recommend forwarding ahead to 19m 50s into the video for the specific “no gravity” information.
Independent Unit: Oscillations and Gravity
AP-C Independent Unit: Oscillations and Gravity
As AP-C students in a college course, you have the skills and ability to work and learn independently. Toward that end, starting today we will engage in our second independent work unit, tying up our Oscillations and Gravity units. Between now and ______________________, you are to:
- Read textbook sections 14.1-14.3, 11.1-11.4.
- Watch all APlusPhysics AP-C videos in the “Oscillations” and “Gravitation” sections.
- Watch Walter Lewin MIT OpenCourseWare Videos #11, 13, 14, 22 from course 8.01 Mechanics.
- Complete the attached SHM Equation Analysis Practice worksheet.
- Complete the Oscillations On An Incline Lab Activity.
- Complete the Oscillations WebAssign homework by midnight 12/17 and turn in all work.
- Complete the Gravitation WebAssign homework by midnight on 12/20 and turn in all work.
- Complete the four free response questions in your packet and achieve a score of 100% (answers available to check your work).
- Catch up on your APlusPhysics blog posts (target is one per week), comment on at least one other blog post per week, and rate at least three blog posts.
You may work alone or in groups, and the order and scheduling of your activities is completely up to you. At the beginning of class on ___________________, prior to taking the exam, you are to place your work for items #4 through #8, all stapled together with your name, into the INBOX.
I will be available for guidance if you get stuck, but will recommend you utilize the available resources (including each other) to help you independently first. These resources include, but are not limited to:
- Textbook sections 14.1-14.3, 11.1-11.4
- APlusPhysics AP-C Physics Videos (available from APlusPhysics.com or YouTube)
- Physics Podcasts / Videos: MIT’s OpenCourseWare Physics (Walter Lewin) available on iTunes, YouTube, and other online locations.
