| Term | Definition |
|---|---|
| Curiosity | One of the two C's of being a scientist. |
| Creativity | One of the two C's of being a scientist. |
| Qualitative | Observations that focus on descriptions and using the 5 senses. |
| Quantitative | Observations that focus on measurements and numbers. |
| Metric System | A system of weights and measures. |
| Meter | The base unit used for measuring length in the metric system. |
| Liter | The base unit used for measuring volume in the metric system. |
| Gram | The base unit used for measuring weight/mass in the metric system. |
| Triple-Beam-Balance | A tool used to determine the weight/mass of one or more objects. |
| Graduated Cylinder | A tool used to determine the volume of a liquid. |
| Meniscus | the curved upper surface of a column of liquid. |
| System | a group of objects or units so connected as to form a whole and work, interact, or move interdependently and harmoniously |
| Input | The entrance or changes that go into a system |
| Output | An exit or changes that leave a system |
| Processes | Interactions that you can see in a system. |
| 3 Benefits of Systems | 1. Helps us understand/process the world around us 2. Makes complicated things more simple 3. Helps us solve and identify problems |
| Physical Model | these models are smaller and simpler representations of the thing being studied. |
| Conceptual Model | These models tie together many ideas to explain a phenomenon or event. |
| Mathematical Model | these models are sets of equations that take into account many factors to represent a phenomenon. They are usually done on computers. |
| 3 Benefits of Models | 1. Lets us see what something large or small looks like in smaller form 2.Helps us predict the future 3.Helps us visualize a complex idea |
| Scientific Method | a process for experimentation that is used to explore observations and answer questions. |
| Step #1 of the scientific method | Ask a question |
| Step #2 of the scientific method | Do background research |
| Step #3 of the scientific method | Construct a hypothesis |
| Step #4 of the scientific method | Test with an experiment |
| Step #5 of the scientific method | Analyze data and draw conclusions |
| Step #6 of the scientific method | Communicate results |
| Hypothesis | a possible answer or tentative solution for a question. |
| 3 Requirements for a hypothesis | 1. Must be based on observations and logical reasoning 2. Must explain a natural phenomenon 3. Must be testable through scientific investigation |
| Variables | things that vary or change |
| Independent Variable | the variable that you change |
| Dependent Variable | the variable that you measure |
| Control Variable | the variable that stays the same |
| Accuracy | how close the measurement is to the correct value |
| Precision | how close the measurement is to the other measurements |
