Intro to Science
The control variables are the things you...
keep the same
Particles are spread apart, move in straight lines and fill their container.
Gas
A friction force caused by air pushing against a moving object.
Air Resistance
Used to pick up or hold hot objects
Tongs
Boiling point of water
100 degree Celsius
Another word for a hypothesis is...
a prediction
Liquid turning into a gas
The size or strength of a force.
Magnitude
Used to measure volume very precisely
Graduated Cylinder
How many days does it take for the earth to orbit the sun?
365.25 days
The independent variable is the thing you...
change
In high temperatures, particles gain energy and push apart. For example, a balloon getting bigger in the sun.
Expansion
Forces that are not equal, causing an object to speed up, slow down, or change direction.
Unbalanced forces
Used to heat objects
Bunsen Burner
Fourth planet from the sun
Mars
The dependent variable is the thing you...
measure
Particles are in a uniform pattern and vibrate in fixed positions.
Solid
Forces that are equal in size and opposite in direction, causing no change in motion
Balanced forces
Protects benches from burns and stains
Heat Proof Mat
How long do blue whales live for?
80-90 years
What is Quantitative data?
Measurements using numbers
the passive movement of particles from an area of higher concentration to an area of lower concentration
Diffusion
The force of gravity acting on an object.
Weight
Separates tripods and glassware.
