The very first step of the scientific method.
What is observation?
Tool that measures mass.
Matter is anything that has __________ and ________________.
Mass and Volume
The question we investigated with paper airplanes.
Which design flies the farthest?
True or False: Air is matter.
True
An observation-based prediction that can be tested.
What is hypothesis?
What is a graduated cylinder?
State of matter that has a definite shape and volume.
What is a solid?
The independent variable in the airplane experiment.
What was airplane design?
Which mass weighs less on the moon: your mass or your weight?
Data that uses numbers and measurements.
What is quantitative data?
What is a centimeter?
State of matter with a definite volume but not a definite shape.
What is a liquid?
Dependent variable in the airplane experiment.
What is distance flown?
Which is larger: a liter or a millileter?
A liter.
Variable that is changed intentionally (on purpose) in an experiment.
What is the independent variable?
This is where you begin measuring when using a ruler.
Process when a gas transforms directly into a solid.
What is deposition?
One constant we kept the same during the airplane experiment.
What is the same thrower / same paper / same starting line / same number of throws?
Which state of matter is steam?
Gas
Reasons for scientists repeating experiments.
What are verifying results and increasing reliability?
Method used for finding the volume of a small irregular object.
What is water displacement?
The process of a solid directly becoming a gas.
What is sublimation?
Why did we use the same thrower each time in the paper airplane distance experiment?
To keep the experiment fair by controlling variables.
A scientist wants to test whether sunlight affects plant growth. What would be the independent variable?
Amount of sunlight
