Closing Up Shop

Today was the last time, in the 2009-2010 school year that the Vernier lab equipment will be used. Now, time to pack everything away and wait for September.

Honors Physics and Physics worked on their circuit projects. Good time being had by all.

Physical Science B conducted their radiation investigation. Students tested how both distance and shielding affect radiation intensity. For both factors, an inverse relationship was seen, with the distance relationship very nicely playing out as an inverse-square relationship. /for the shielding experiment, more shielding definitely lowered the number of counts/time interval, but the relationship was more linear. We';; discuss the lab tomorrow and finish up with radiation by discussing fission, fusion and radiation uses and safety,

Physical Science E returned to radioactivity with a description of gamma rays and the nature o decay series. Attention was then turned to radioactive half-life an dhow it can be used to assess the age of materials. Tomorrow, we'll go over the half-life problems assigned for homework and finish up with our radiation unit.

Both Physical Science sections received a copy of last year's final exam and the solution key. With the extensive preparation for MCAS that we recently completed, students have already had their final exam review. Take the exam, score your test and make note of items and topics for which you need extra help. Schedule time with me between now the and your exam period to get the help you need and email me if you have questions.
