9G Test 1 - Study Guide - Scien fic Method and Ecology Scien fic Method 1. Be able to explain the steps of the scien fic method including ○ defining a problem/ asking a ques ons ○ observa ons ○ hypothesis ○ data collec on - through qualita ve or quan ta ve data ○ independent and dependent variables ○ control and experimental groups/setups ○ conclusions ○ Be able to list constants if given an experiment ○ Be able to dis nguish between an observa on and an inference 2. Know how to graph data (graphs include: appropriate tle, labeled axes with units, equal intervals, independent variable on the X axis and dependent variable on the Y axis). Know how to determine what the range is for your axes and data in order to calculate intervals. 3. Be able to explain when to use a line graph or bar graph. 4. Be able to explain how you can ensure that the results of an experiment are accurate 5. Be able to state the range of data in an experiment Ecology 1. What is ecology?

Be able to explain, iden fy, and give examples of the following rela onships between organisms: compe on, herbivory, preda on, and symbiosis (mutualism and parasi sm). Know the terms applied to the members of each interac on (e.g. predator, prey, parasite, host). a. Be familiar with adapta ons/ characteris cs that predators and prey have 6. What is a food chain/web?
