Scientific Method Used to answer a question using an experiment Steps Question Research Hypothesis: educated guess of what you think is true, in a statement form Experiment Data analysis Conclusion Independent variable: what scientist is changing Dependent variable: what we measure Control: used to compare Constants: factors that we keep the same across all treatment groups Theory: hypothesis that has been tested over and over and is now considered true. Characteristics of life Made of cells and DNA Metabolism Cells are basic unit of life All require and use energy DNA is the genetic material in the cell Plants: use photosynthesis to build food Unicellular: 1 cell big Multicellular: made of (autotroph) many cells Animals: break down food to release energy (heterotroph ) Reproduction: produce offspring Growth and development Asexual: 1 parent and offspring identical to Grow and chaing during life cycle parent Sexual: 2 parents and offspring unique Adapt and change Maintain homeostasis Respond to environmentCactus adapted to desert
