| 465568034 | Scientific Investigation | The process by which a scientist asks a question about the natural world, collects and analyzes data to help answer that question, and communicates the results to the scientific community | 0 | |
| 465568035 | Homeostasis | maintaining a stable internal environment | 1 | |
| 465568036 | Cells | The basic unit of all living things | 2 | |
| 465568037 | Eukaryotic Cell | cell with a nucleus (surrounded by its own membrane) and other internal organelles | 3 | |
| 465568038 | 8 Characteristics of Life | 1. Made of one or more cells 2. Displays organization 3. Grows and Develops 4. Reproduces 5. Responds to stimuli 6. Requires Energy 7. Maintains Homeostasis 8. Adaptations evolve over time | 4 | |
| 465568039 | Hypothesis | an educated guess to the problem or a prediction of the results; usually written as an IF .... THEN statement | 5 | |
| 465568040 | Independent Variable | The one factor changed by the scientist. The IF part of the hypothesis, graphed on the x-axis | 6 | |
| 465568041 | Dependent Variable | The variable being affected, observed and/or measured. The THEN part of the hypothesis, graphed on the y-axis. | 7 | |
| 465568042 | Control Group | in an experiment, a group that serves as a standard of comparison with another group to which the control group is identical except for one factor | 8 | |
| 465568043 | Constants | conditions that stay the same in the experiment | 9 | |

| 465568046 | Pie Graphs | shows how facts and figures relate to each other by presenting them as portions of a circle | 12 | |
| 465568047 | Line Graphs | Visual display that show how two variable are related, independent variable platted on horizontal x axis, dependent variable platted on the vertical y axis | 13 | |
| 465568048 | Bar Graph | a type of graph in which the lengths of bars are used to represent and compare data in categories | 14 | |
| 465568049 | Theory | A well tested explanation of many scientific observations | 15 |
