- observations of living organisms are recorded in the lab and in the field;
- hypotheses are formulated based on direct observations and information from scientific literature;
- variables are defined and investigations are designed to test hypotheses;
- graphing and arithmetic calculations are used as tools in data analysis;
- conclusions are formed based on recorded quantitative and qualitative data;
- sources of error inherent in experimental design are identified and discussed;
- validity of data is determined;
- chemicals and equipment are used in a safe manner;
- appropriate technology including computers, graphing calculators, and probeware is used for gathering and analyzing data, communicating results, modeling concepts, and simulating experimental conditions;
