I have copied, from the NCEA site, details where the logbook is mentioned and I guess, if he has all his data processing in his report, then that would be OK to achieve the standard? Were the 6 students all in the same class or were they randomly distributed throughout different classes.

The models are wrong about feedbacks and the hotspot. I now am looking at the moderation report we recieved last year and find that the comment for 1 student's report was that "It is not good practice to use sodium thoisulphate as a primary standard". Surplus opened stock is usually discarded at the end of the investigation.

The Shell Game — pretend evidence for 1 degree is really evidence for 3 degrees The unskeptical Guide claims there are multiple lines of evidence that show humans cause global warming.

Do you take the lower of the two teacher values, which rewards low titre values but penalises larger ones and those "colourblind" students? For professionals, we now have a business center fully furnished and equipped internet, video conferencing room, etc.

Page 78 suggests 4 is the minimum for Merit, with at least 3 determinations titration for each. Even though the content of Mg or Ca may not change, students don't seem to realise this.

Madagascar, agri-food hub for the Indian Ocean. Instead they must modify a variable to produce a possible trend eg temperature to quote the standard. On posture as a modality for expressing and recognizing emotions. Provided they are measuring the changing concentration quantitatively with a spectrophotometer or colorimeter and not just by eye, and it meets the other criteria for the standard I can't personally see a problem myself.

Thanks for the feedback. In those interactions, the energy gained by electrons in the solid is often sufficient to ionize them; the electrons thus ionized are called secondary electrons SE.

And the same sort of thing with opened wine bottles and hypochlorite bleach.

Please remind me why the aspirin investigation would not be suitable, yet the acetic acid in vinegar would. I have come across the heating effect with my own students previously and my best bet is that heating cause some of the organic molecules present in the sample to be hydrolysed or in some way broken down into simpler molecules that the iodine is able to oxidize — hence producing increasing titre values when a direct iodine titration is used or a reducing titre value if the back titration method is used.Search the world's information, including webpages, images, videos and more.

Google has many special features to help you find exactly what you're looking for. One of the oft-cited objections to the term “greenhouse effect” is that it is a misnomer, that a real greenhouse (you know, the kind you grow plants in) doesn’t work by inhibiting infrared energy loss.
