Question | Answer |
Capacity | The greatest amount of fluid a container can hold. |
Line of Best Fit | Shows the trend of the data in a graph; it tries to "average" the data in the graph. |
Density | The measure of the amount of mass (matter) per volume. ~m/v~ |
Volume | The amount of space an object occupies. |
Mass | Amount of matter in an object. |
Dependent Variables | The info learned during an experiment. It can be measured and goes on the y-axis. |
Water Displacement | The amount of water pushed aside or moved by the boat. The mass of water that is pushed aside is equal to the mass of the boat. |
Two-Coordinate Graph | A drawing showing the relationship between two sets of data consists of two axis, the x-axis and the y-axis. |
Independent Variable | The known info at the beginning of an experiment, ban be measured, and is on the x-axis of a graph. |
What variables might affect the # of pennies a paper cup can hold? | ~ Penny placement ~ Water movement ~ Size of cup |
Is there a relationship between the capacity of lifeboats and the # of pennies they hold? | No, the greater the capacity, the more pennies a boat can hold. |
How were you able to predict the # of pennies a new boat would hold? | Using the two coordinate graph and the line of best fit. |
Did any results surprise you? If so, what do you think happened. | Unexpected results may have come from changing more variables than just boat capacity. |
Scientific Inquiry Steps in order | 1. Making observation 2. Ask a question 3. hypothesis 4. test hypothesis/ experiment 5. analyze data/ results/ make a conclusion 6. publish data |
