AICE marine science AS Level Exam review paper 1, 2 Questions and Answers 100% Pass scientific method - Correct Answer ️️ -1. for valid experiments, data should be collected numerous times (the more times, the more accurate) 2. only one variable (independent) should be changed in an experiment. All others should be controlled. The deponent variable is dependent upon what you changed-it will be what you are measuring in n experiment 3. quantitative results- numbers (qualitative=descriptive words) outlining/designing an experiment - Correct Answer ️️ --state amount of containers e.g. 5 tanks of each -state constants (at minimum 3) (light, salinity, amount of water, how often results are calculated, amount f exposure/days etc.) -what is the amount of independent variables used? pick a quantity suitable for the experiment appropriate to the experiment -state the duration of the entire experiment -state the calculating results. most common is simple counting -state repeat experimentation and calculate mean/average from all trials describing results of an experiment - Correct Answer ️️ --state the most with reference to data -state the least with reference to data -manipulate data by finding range creating or working with graphs - Correct Answer ️️ --use the entire graph -correctly label the x and y axis -use correct intervals. do not use breaks to begin at certain number. each interval is equally spaced. use appropriate scale the divide the total number of spaces on the graph by the range. this will give you your interval. -when constructing a graph, make sure your scale is appropriate to show a relationship- you may need to have values on the axis to the left and to the right -plot all points correctly -line of best fit explain what would be needed to turn an experiment into a theory - Correct Answer ️️ - -rigorous testing -repeated testing by many/other scientist -scientist get similar results but with the same conclusions no exception symbiosis - Correct Answer ️️ -remember that aice looks at symbiosis and mutualism one in the same. it is a close relationship between 2 different species where both benefit. make sure you explain what both are getting/giving. examples: coral and zooxanthellae; tube worms and chemo. bacteria arrows in a food chain - Correct Answer ️️ -or food web represent: transfer engery and biomass -do not use the words "eats," instead, use consumes
