Amanda Beseda Scientific Method/Pendulum Exercise Worksheet 1. What is the difference between an observation and an inference? Observations are based on collecting knowledge through our senses. An inference is making an educated guess based on observation. 2. In doing science‚ why are hypotheses either supported or not supported‚ but never proved beyond all doubt? There are many other factors that could be unknown and new data could be found in the future to support or not support a hypothesis

EXPERIMENT 11: DETERMINATION OF DISSOLVED OXYGEN IN A WATER SAMPLE (WINKLER METHOD) INTRODUCTION In an alkaline solution‚ dissolved oxygen will oxidize manganese(II) to the trivalent state. 8OH-(aq) + 4Mn2+(aq) + 2H2O(l) －－＞ 4Mn(OH)3(s) The analysis is completed by titrating the iodine produced from potassium iodide by manganese(III) hydroxide. 2Mn(OH)3(s) + 2I-(aq) + 6 H+(aq) －－＞ 2Mn2+(aq) + I2(aq) + 6H2O(l) Sodium thiosulphate is used as the titrant. Success of the method is critically

Introduction In this experiment I aim to find out if caffeine has an effect on the heart rate of daphnia. Daphnia are water fleas that have a sort of heart that we can see in magnification. We can count the number of heart beats in a minute of a regular daphnia and try and get a new one with the same specifications as the old one that may have died. It is also a good idea to get a new one as we want to see how much it affects it from ordinary instead of adding the caffeine one after another

The Bandura et al experiment in 1961 conducted research into how we can transmit aggression through imitating aggressive models. 36 boys and 36 girls aged between 37 and 69 months were subject to this experiment. There were 3 conditions‚ the control group‚ the group exposed to the aggressive model and the group exposed to the passive model. In the standard condition‚ a child was settled in a corner with a small table and chair‚ potato prints and picture stickers. An adult model was then escorted
