Investigation 2 Life

vocab./content/scientific inquiry

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
