3A Task 1 Aim: the aim of the experiment is to find the best temperature to ferment yeast at. Hypothesis: the yeast will ferment the best at 60 degrees Celsius. Independent variable: the temperature of the water the yeast is put in to ferment. Dependent variable. The amount of air bubbles the yeast produces. Controlled variable: the amount of yeast and glucose in each syringe. Uncontrolled variables: human error in counting. Materials : Plastic soft drink bottle cut to size Marking pen

PROBLEM STATEMENT: What affect does water temperature have on the amount of light given off from a fishing glow-stick? RESEARCH: Some advertisers claim that glow stick products can attract greater numbers of fish thus increasing their catch. It has been known for centuries a number of aquatic organisms are attracted to light. Some advertisers claim that the use of ’glow stick’ type porducts attract greater numbers of fish. They are attached to the fishing line near the fishhook. Many of the Washington

Elena Mesa Nov. 15‚ 2013 Ms. Lelacheur IB Biology HL The Effect of Temperature on Beet Root Membranes What is the affect of temperature on beetroot membranes? Hypothesis: It is hypothesized that as the temperature increases‚ the deeper red the beetroot water will be. At higher temperatures the proteins in the beetroot plasma membrane will denature‚ leaving holes in the membrane and allowing the red pigment in the cell sap to seep out into the water around it. Variables: Dependent-The

Yeast Experiment – Temperature Yeast fermentation is affected by temperature as an outcome of the many different temperatures that yeasts are exposed to. The accepted value for yeasts optimum temperature is approximately 66.667 degrees Celsius. If yeast is exposed to their optimum temperature‚ then this would create the most amount of fermentation. In this experiment however‚ the yeast were exposed to temperatures below their optimum. The chemical reactions within yeast are facilitated by enzymes;

The doctrine of fundamental change of circumstances‚ (rebus sic stantibus) is a principle of customary international law allowing a part to an agreement to withdraw or terminate it where there has been a fundamental change in circumstances. The main justification for this principle is that treaties often remain in force for many years‚ during which time fundamental changes may occur in the political or international environment which may require a departure from the provisions set out in the treaty

Peter Goldsworthy’s Maestro demonstrates the importance of setting in understanding characters such as the protagonists Paul Crabbe and Eduard Keller. Written in a retrospective narrative from Paul Crabbe’s point of view and how the settings of ‘steamy’ Darwin‚ ‘suburban’ Adelaide and ‘hypocritical’ Vienna affected him.

The use of techniques to create distinctively visual images which help us to convey an understanding and form a meaning is evident in the novel Maestro by Peter Goldsworthy‚ the film Blade Runner directed by Ridley Scott‚ and the poem Mending Wall by Robert Frost. The clear visual images that Goldsworthy uses in Maestro through his techniques affect the interpretation and help shape the meaning of the characters and blossoming setting which reveal aspects of these characters.
