one type of act science<\/a> passage, research summaries, will present descriptions of one or more related experiments and will require you to answer questions about one or both experiments. to compare them accurately, answer the following questions as you read:<\/p>\n how is each experiment set up?<\/b> make sure you understand the method for each experiment. what tools\/processes\/chemicals are used?<\/p>\n what does the data show?<\/b> pay close attention to the results of each experiment. usually this is presented in tables or charts. how do the different variables relate to one another? draw arrows on the tables to show the trends.<\/p>\n how do the experiments differ?<\/b> there will be certain elements common to both experiments, and one or more elements will change from experiment 1 to experiment 2. circle the new information. then focus on the results \u2013 do the variables interact similarly or differently in the 2nd<\/sup> experiment? is the range of data greater or smaller?<\/p>\n try a sample passage and practice question!<\/p>\n <\/p>\n a student wishes to discover for herself what effects, if any, pressure and temperature have on the solubility of various solutes in water.\u00a0 the solute of a solution is the substance that is dissolved by the solvent.<\/p>\n <\/p>\n at a constant pressure of 770 torr, a student tested the solubility of five compounds at different temperatures.\u00a0 in order to do this, the student started with 100g of water and gradually added the solutes, in five separate trials, until no more of that solute could dissolve.\u00a0 all of the solutes tested in this experiment were in the solid state unless otherwise indicated.\u00a0 the results of this experiment are summarized in table 1.<\/p>\npassage i<\/h2>\n
