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 |
