Make ObservationsObservation prompts scientists to beginan Ask QuestionsThough any type of question is good, the answers shouldalso be able to measure Construct a HypothesisA hypothesis is a possible for whysomething occurs. The experiment should be able toprove whether the hypothesis is true or false. Test the HypothesisA good experiment controls as many factors as possible, so that a single factor, called the canbe tested. the experiment ensures thatthe variable causes the change observedin the experiment. Analyze the ResultsAn experiment always give the same results as the hypothesis. A hypothesis is accurateonly when scientists get the same results by repeating the experiment several times. Repeat, or RetestMary’s first trial her hypothesis. She repeated the experiment two more times with new plants, and she saw the same results both times. ConcludeAfter completing their experiments and analyzing theresults, scientists form a Communicate the ResultsScience is a collection of Scientists conduct experiments and publish results inscientific

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.
