Vocabulary
Description of how close a measurement is to the actual or true value
What is accuracy?
What is biology?
The unit of measurement for the volume of a solid object.
What is cubic centimeters?
This is the variable that is being manipulated or changed in an experiment
What is the test/independent variable?
What you use to record and display your data when looking for relationships among the variables.
What is a data table or graph?
After makings observations you begin to draw these conclusions.
What is an inference?
The type of data the scientists record from making observations based on measurements in science?
What is quantitative data?
Tool used to measure mass.
What is triple-beam balance?
This is the variable that is being measured or recording due to the change.
What is the outcome/dependent variable?
After making observations and inferences you create this which is a possible explanation of your observations and can be tested.
What is a hypothesis?
The amount of space an object occupies
What is volume?
A representation of something in the natural world, typically too small or large to study up close.
What is a model?
The unit of measurement for the density of a solid object.
What is g/cm3 (grams per centimeters cubed or cubic centimeters)?
The variables that remain the same for all trials in an investigation so that the experiment can be VALID.
What are constants?
If your hypothesis is supported by your data, this is the next step in the process.
What is repeat the test again or to have another scientist replicate the experiment?
A well-supported explanation of the natural world (hint: explains WHY something happens).
What is theory?
DAILY DOUBLE: Name three forms of collecting scientific data. When you want to change something, when you do not want to change something and when you cannot simply observe.
What are controlled experiments, observational investigations and scientific models.
The formula for density.
The name of the group that is observed before any changes are made to an experiment. This group is used to compare your results.
What is the control group?
The axis that is used to plot the outcome/dependent variable.
What is the y axis?
Describes a basic principle of nature that always occurs under certain conditions (hint: explains HOW something happens).
What is a law?
You can only have one of these in a valid controlled experiment.
What is a test/independent variable?
The type of graph that is used to shows changes or trends over a period of time.
What is a line graph
DAILY DOUBLE: How is the rate of a falling object effected by the size of the parachute. The independent variable. The dependent variable.
What is the size of the parachute for the independent variable?
What is the rate of a falling object for the dependent variable?
This is a visual representation of a scientific concept that is too difficult to study because it is either to dangerous, too far away, does not exist anymore or happens too slowly.
