| Question | Answer |
|---|---|
| What are the foundations of science? | Order, Reality, Experience, Curiosity. |
| What is an observation? | The process of observing someone/something to gain information. |
| What is an inference? | The process of drawing conclusions based on evidence and reasoning. |
| Difference between observation and inference? | Observation= something easily seen ( use of 5 senses ), Inference= guess/idea that needs to be supported |
| What is a manipulated variable? | A variable found in experiments. Changing the variable to learn how other variables in the experiment respond. |
| What is an independant variable? | A variable that stands alone/variable that isn't changed. |
| What are constants? | The factors that do not change during experiments. |
| Difference between theories and laws? | Theory= answers why/tested repeatedly/been approved, Laws= mathematical/scientific statement/tell how it happens |
| What do laws/theories do? | Theory= allows scientists to make predictions of what they should observe if a theory is true, Laws= describe how something happens |
| What are the limitation of science? | Not being able to answer questions that deal with opinions, beliefs, values, and feelings. |
| Difference between precision and accuracy? | Accuracy= refers to how close a measurement is to the true or accepted value Precision= refers to how close measurements of the same item are to eachother |
| Difference between qualitative and quantitative data? | Qualitative= descriptive, related to language data Quantitative= number-based/measureable data |
| Remember meaning of precise and accurate= | Precise= close together, not exactly on target Accurate= in the target, may not be precise though |
| steps of scientific inquiry? | 1. Question/observation 2. describing/explaining 3. Hypothesis 4.experimenting 5. Analyze Data 6. Conclusions 7. Communicating |
| identify theories and laws. | Theories= theory of gravitiation, explains why apples fall from trees and why astronauts float in space, they explain Laws= The law of conversation of energy, they describe |
| noticing difference between observations and inferences. | Observation= using 1 or more of your 5 senses to gain information, can be easily seen inference= drawn conclusions based on evidence, ex: guessing what or when |
| be prepared to determine measurements on images | look closely, memorize amounts and what they look like, ex: 1/4 cup |
