6) The results are quantitative. For something to be quantitative it must be of, relating to, or susceptible of measurement. The students counted the number of living organisms, which they observed in the local park each day. Therefore there results are quantitative.


7) Between weeks 6 & 7 and weeks 9 & 10 the number of bees increased the most.


8) The statement that Demelza said to Jess is an hypothesis. In the results the number of birds and butterflies seem to be linked. The higher the number of birds, the more butterflies. There is no full evidence to support this hypothesis except for the results from the girls observations throughout the week.


9) Palaeontology is the study of the forms of life existing in prehistoric or geologic times, as signified by the fossils of plants, animals, and other organisms.

Scientific Method II
1) The essential piece of the apparatus, which is missing, is a thermometer.


2) This piece of equipment it used to measure the temperature of the water to determine the rate at which it cools


3) The 250mL glass beaker could be replaced


4) A measuring cylinder


5) To ensure a more accurate reading and therefore results


6) The factors, which would need to be controlled during this experiment, would be: a) the position of the flasks. Whether they are all in the sun, all in the shade.


b)


7)


8)

10) 80 Celsius 11) 25


12) The results for the white aluminium beaker


13) Water, which contained in silver containers tends to keep its temperature for a lot longer than water, which is not. The amount of time for which a liquid is kept at a certain temperature therefore relies on the colour of the container in which it is kept.


14) A vacuum flask or Dewar flask has the remarkable capacity to hold extremely cold liquids like liquid nitrogen for a considerable length of time. This is due to the fact that it is able to effectively block heat transfer from the outside either through the walls or through the open top. The silvered vacuum jacket effectively blocks all three standard heat transfer mechanisms.
