| Cells | The basic unit of life that consist of DNA and is surrounded by a Cell Membrane |
| Tissue | A group of similar cells that work together |
| Organ | A group of tissues that work together |
| Organ Systems | A group of organs that work together |
| Organism | A complete living thing |
| Life Processes | Things that living have to do |
| Growth | An increase in size or number of cells |
| Excretion | Getting rid of metabolic wastes |
| Transport | Moving needed materials around also known as circulation |
| Metabolism | The sun of all life Processes (not an actual life process) |
| Respiration | Turning food into energy called ATP and releasing |
| Synthesis | To make or build |
| Regulation | Controlling the internal environment |
| Homeostasis | Maintaining a stable internal environment called equilibrium |
| Reproduction | Making more organisms of the same kind |
| Nutrition | Obtaining needed materials called nutrients |
| Dichotomous | To divide into two groups |
| Modern Classification | Grouping things according to their similarities and structure |
| Domain | The largest classification category. More Organisms with more differences |
| Species | The smallest classification category. Less organisms with more similarities. |
| Scientific Names | Genus then Species. Genus is always capitalized and species is always lowercase. ALWAYS TYPE IN ITALICS OR UNDERLINE |
| Scientific Method | Process scientists use to logically solve a problem |
| Observation | Use the five senses to gather information |
| Question | Describes the problem and determines what you want to know about the situation |
| Hypothesis | Based upon what you've learned from observations and prior knowledge to form a logical explanation |
| Experiment | Tests that hypothesis by doing a controlled experiment |
| Conclusion | Analyze the data |
| Inference | Logical conclusions based on observations |
| Qualitative Observations | Observations that use your senses (touch, hear, sight, smell, taste) to observe the results |
| Quantitative Observations | Observations that are made with equipment such as rulers, balances, graduated cylinders, beakers, and thermometers |
| Hypothesis | Possible explanation that accounts for a set of observations. Worded as If, Then statement. |
| Controlled Experiment | To test a hypothesis scientists set up a controlled experiment which must have two groups that are the same except for one thing |
| Experimental Group | The group being tested and receives the independent variable |
| Control Group | The group that does not get the independent variable being tested by the scientist. Used for comparison. |
