Unit 1 - Sci Inquiry
| Term | Definition |
|---|---|
| Observation | information gathered using the five senses |
| Qualitative Observation (QL) (Definition) | an observation that describes an object with words |
| Qualitative Observation (QL) (Examples) | color, taste, texture |
| Quantitative Observation (QT) (Definition) | an observation that uses measurements to describe an object |
| Quantitative Observation (QT) (Example) | a temperture of 5 degrees Celcuis, My house is 5 miles from the school. |
| Inference | an interpertation from observations |
| Scientific Method (Definition) | a series of steps used to solve a problem |
| Scientific Method (Steps) | 1. Identify the problem 2. Make a hypothesis 3. Experiment (collect data) 4. Draw conclusions 5. Communicate results |
| Controlled Experiment | an experiment where only one variable is changed and all others remain constant |
| Independent Variable (IV) | the variable that is changed by the scientist |
| Dependant Variable (DV) | the variable that reponds to the change, what is being measured |
| Hypothesis | an educated guess about the solution to a problem |
| Control Group | This is what would naturally occur, used to compare your data too |
| Experiment | organized process used to test a hypothesis |
| Conclusion | a claim based on the results of an experiment |
| Data | Observations and measurements recoreded during an experiment |
| The metric system | a uniform system of measurement which allows for easy comparison of data |
| Length - definition - instrument - unit | - the distance between two points - ruler - meters (m) |
| Volume of a Regularly Shaped Object - definition - instrument - unit | - the amount of space an object takes up - ruler - cm *3 |
| Volume of an Irregularly Shaped Object - definition - instrument - unit | - the amount of space an object takes up - graduated cylinder - mL |
| Water displacement method | This is when you fill a graduated cylinder and record the measurement (old), then slide the object in and record the new measurement. Lastly you subtract New - Old to get the volume of just the object. |
| Mass - definition - instrument - unit | - the amount of matter in an object - scale - grams |
| Weight (Definition) | the force of gravity pulling on an object |
| Density (Definition) | the concentration of matter in an object |
| Explain why some materials float in water | A material with a density less than the density of water will float (less than 1 gram/cm*3) |
| Explain why some materials sink in water | A material with a density more than the density of water will sink (more than 1 gram/cm*3) |
