Chemistry 5-3-10 (Mon.)

// May 3rd, 2010 // 1 Comment » // Chemistry

Today we went over the Ch 16 test. We will be skipping to Ch 19 next in case you want to start reading and doing the vocab.
Ch 19 will be the last chapter for the semester.

If you are reading this, you may be interested to know that next fall Byng Schools will have a new interface for the school website.

I have been testing, reviewing and assisting with the implementation of the new system. Hopefully it will be an even better tool for communication between the school, families and community.

If you have been checking in recently I apologize for not updating the blog daily. It has been slipping my mind during the day due to track meets/practices, being sick, and trying to spend every other spare second at school getting my advisory students enrolled.

Chemistry is still working on Ch 14. We did demos on Boyle’s Law today as well as work problems for the combined gas law. Worksheets may be due as early as Tuesday.

Physics is nearing completion of Ch 14 also (Waves). Today we covered superposition (constructive and destructive interference). We watched some applets demonstrating interference. We also took 10 minutes to learn how to juggle –Hey, I read where there is a connection between learning to juggle and cognitive functioning so it seemed like a good idea. LOL Worksheets will be due Tuesday for Physics also.

Chemistry 3-24-10 (Wed)

// March 24th, 2010 // No Comments » // Chemistry

Today we discussed Ideal vs Real gases, Dalton’s Law of Partial Pressure, and Boyle’s Law.

These topics are in the Ch 14 Powerpoint file.

My photos. Now you know me.

Vitamin D is a prognostic marker in heart failure, study finds September 5, 2010
Survival rates in heart failure patients with reduced levels of vitamin D are lower than in patients with normal levels. This is the finding of a major study carried out in the Netherlands. […]
New pump created for microneedle drug-delivery patch September 5, 2010
Researchers have developed a new type of pump for drug-delivery patches that might use arrays of "microneedles" to deliver a wider range of medications than now possible with conventional patches. […]
Mothers matter! High social status and maternal support play an important role in mating success of male bonobos September 5, 2010
The higher up a male bonobo is placed in the social hierarchy, the greater his mating success is with female bonobos, researchers have found. But even males who are not so highly placed still have a chance of impressing females. A new study finds evidence of direct support from mothers to their sons in agonistic conflicts over access to estrous females. […]
Did Viking Mars landers find life's building blocks? Missing piece inspires new look at puzzle September 5, 2010
Experiments prompted by a 2008 surprise from NASA's Phoenix Mars Lander suggest that soil examined by NASA's Viking Mars landers in 1976 may have contained carbon-based chemical building blocks of life. […]
New bee species discovered in downtown Toronto September 5, 2010
A doctoral student who discovered a new species of bee in Toronto has completed a study of 84 species of sweat bees in Canada. Nineteen of these species are new to science -- never before identified -- including the new Toronto bee, which is actually quite common in eastern Canada and the US. The new research will help scientists track bee diversity, and und […]

Iron deficiency in heart failure September 5, 2010
Iron deficiency is a relatively common nutritional disorder that affects more than one third of the general population, and is often associated with chronic diseases such as inflammatory bowel disease, Parkinson's disease, rheumatoid diseases and renal failure.

Move over, Sunbelt. The New North is coming through, a geographer predicts in a new book. As worldwide population increases by 40 percent over the next 40 years, sparsely populated Canada, Scandinavia, Russia and the northern United States will become formidable economic powers and migration magnets, Laurence C. Smith writes. […]
