Traveling on a magic-powered passenger train or sending a message to someone via a magical equivalent of a telegraph is seen as perfectly normal by most people. So, in summary, the key change is that the purpose of the investigation must be related to a possible trend.
A practical example of this is the use of copper bowls to stabilize egg foams. As a rough guide, one of my students measured the titratable acidity of milk as 0.
What are you going to measure? One example is to react it with an acidified sulfanilamide and N- 1-naphthyl ethylenediamine dihydrochloride to form an intensely coloured dye having maximum absorption at nm. The density can also be used as an index. However, I do sympathise with them because of the wide variation in the nature and type of extended investigations carried out and the need to retain some flexibility for moderators to allow moderators to apply common sense and use a holistic approach to specific cases.
However, as the requirements have changed we're finding it difficult to assist our students with recommendations involving trends.
One of her triumphs was discovering the exact breed of apple and type of knife to use in the old "predict your future husband's name with a thrown apple peel" if you wanted it to actually work; otherwise it would inevitably spell SCSSSC.
Your EEI could be to measure the ammonium ion concentration after a period of time say a week under different conditions that may affect the bacteria temperature, oxygen availability, pH, salinity, light.
After two hours, to allow the dye to diffuse into the agar final concentration 0.
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.
If completely dry they go into hibernation - but what is optimum? However, assuming that a student decides to investigate the levels of total acid in white wine it seems this would probably have to be with respect to one other variable.
No I have never calibrated, by which I assume you mean weighed the liquid that came out of them?? Have just received back moderation report for this standard.
As the light from the light source is increased and the light coming through the condenser is decreased, stronger contrast will be achieved.
Netchurch is analysing the effects of all sorts of supernatural effects for science. An example here may involve the use of Bromelain found in pineapples to assist in the digestion of proteins.
In Smoke and ShadowsArra comes from an Alternate Universe where humans have developed magic to a greater extent than technology, but still combine it with the physical sciences and employ it in a scientific manner. Due to balance issues, this never really gives them much of an advantage.
The minimum and maximum 'gates' set will critically affect the number of spots counted.
Supposedly they can lower the amount of "bad" bacteria in your digestive system that can cause infections or other problems. As there are lots of organic molecules present in fruit juice or similar that are capable of being oxidized e.
Folding rollfilm cameras were preceded by folding plate cameras, more compact than other designs. I have done CO2 previously by expelling CO2 heating works well as gas solubility reduces hugely with temp into known excess base and then back titrating with standardized acid.
Kellhus learns the Gnosis, a school of magic more dependant on language and possibly mathematics, and promptly becomes even more godlike than he already was. So, no problems with these EDTA titrations, they fit the standard. Aquarium operators have a rule of thumb that says: The agar pad should adhere to one of the slides usually the bottom one.
However, the student could get around this by obtaining tablets of the same brand but with significantly different expiry dates.
Potting mix is usually pH No single disinfectant is ideal. Measure the size of the colony after a few days and then place a square of filter paper on the agar with various amounts of clove oil added and note the growth over the next week.
Tadpoles should hatch out of eggshells. A determination of optimum wavelength for absorption to read at i. Generally, the technique of interaction is determined by the size of the object.
What amount of teacher assistance can be tolerated during the investigation? In the context of a rate investigation this doesn't matter but perhaps it could be a problem wrt meeting the requirements of 3. J ust a check, I have a student who is analysing iron tablets for his investigation, Do you know if the permanganate required to titrate against is 0.Many of the suggestions below involve the use of animals.
Various laws apply to the use of animals in schools particularly any "live non-human vertebrate, that is fish, amphibians, reptiles, birds and mammals, encompassing domestic animals, purpose-bred animals, livestock, wildlife, and also cephalopods such as octopus and squid".
