In our hypothesis we predicted that the enzymes in the pineapple will denature when the temperature is changed. The prediction was partly correct. Pineapples have special enzymes that denature gelatin molecules. Which is the reason why the pineapple and gelatin test tube remained filled with liquid‚ instead of turning into jelly which gelatin does when it’s molecules are not disturbed.

10. Errors and Redesign. Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways.

The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by

Compare and contrast expectancy and goal setting theories of work motivation. Which do you find the more useful and why? Two of the best known approaches to work motivation are the expectancy theory introduced by Victor Vroom (1964) and the goal-setting theory introduced by Edwin A. Locke (1968).

The mass of the fan cart was the independent variable and acceleration was the dependent variable. We kept the speed of the cart on medium‚ and calculated the acceleration and motion. As a result‚ we had figured out that the bigger the mass the slower the acceleration‚ as we all should have known. To calculate this we used
