Scholarship students sitting their chemistry exam at the end of last year were asked to explain the reaction process that takes place in a date-rape drug. In the NCEA exam administered by the New Zealand Qualifications Authority (NZQA) students were told rohypnol, commonly known as roofies, was a "controversial sedative which has sometimes been used to spike people's drinks". An NZQA spokeswoman said the exam papers were written by a team including experienced teachers who were currently teaching at scholarship level. "All examination papers undergo a sensitivity check and this examination did go through that process." While the question referring to the date-rape drug raised some concern during the screening process, it was deemed appropriate and published because most of the students sitting the exam would be 18. "The candidates sitting the examination are considered the brightest senior secondary school chemistry students. The question and answer did not involve or require any value judgment being made, and no information about the making of the drug was provided," an NZQA spokeswoman said. While no complaints had been received about the chemistry question it was "noted" by one other person on the day of the exam.

How do your clothes go from filthy to grunge free? Through the chemistry of laundry detergent. In the latest installment of our Appliance Science column, we look at the chemistry of clean clothes. Sunlight Laundry Detergent ad from the 1920sWellcome TrustThere's one thing that most people don't realize about the past: it was a filthy, filthy place. Even ignoring the people themselves, the clothes that we have worn for most of human history have been stained, dusty and crusted with all sorts of unpleasantness. We've worn them for a long time, getting them sweaty, dirty and generally covered in all sorts of icky stuff. Fortunately, much of humanity doesn't have that issue anymore, thanks to the discovery of laundry detergents. Today, we can throw some socks in a washing machine and have them clean in a few minutes, thanks to the remarkable efficiency of laundry detergents at getting the dirt out of your clothes. Modern laundry detergents contain a huge array of chemicals that help the cleaning process and make your clothes look nice, including chemicals that digest stains, clean the water and perform many other tasks. We'll discuss more of these in future columns, but for right now, let's … Continue reading →
