Experiments
A thing that changes (or "varies") in an experiment
What is a VARIABLE?
This is the SI unit of force (and weight)
What is the NEWTON?
This is an eclipse that makes the moon seem to disappear
What is a LUNAR ECLIPSE?
The imaginary straight line the Earth rotates around
What is the EARTH'S AXIS?
A three dimensional round object
What is a SPHERE?
The variable the experimenter changes
What is the independent variable?
This is Newton's law that says an object in motion tends to stay in motion and an object at rest tends to stay at rest.
What is NEWTON'S FIRST LAW, (A.K.A. THE LAW OF INERTIA?)
This is an eclipse that seems to blot out the sun and create darkness in daytime
What is a SOLAR ECLIPSE?
The reason there are seasons
What is the TILT OF THE EARTH'S AXIS?
This means "half of a sphere" in Greek
What is HEMISPHERE?
The measurement that changes in response to what the experimenter changes
What is the DEPENDENT VARIABLE?
This is Newton's Law that says every action has an equal and opposite reaction
What is NEWTON'S THIRD LAW OF MOTION?
This is the darkest part of the Earth's shadow in an eclipse
What is the UMBRA?
The season when Earth's axis is tilted MOST toward the sun
What is SUMMER?
The hemisphere where Tulsa is
What is the WESTERN or NORTHERN HEMISPHERE?
The thing the experimenter keeps the same
What is the CONTROLLED VARIABLE?
This is Newton's law that says Force equals Mass times Acceleration (F=m*a)
What is NEWTON'S SECOND LAW?
This is the lighter part of the Earth's shadow in an eclipse
What is the PENUMBRA?
The season when Earth's axis is tilted LEAST toward the sun
What is WINTER?
This is the hemisphere Antarctica is in
What is the SOUTHERN HEMISPHERE?
The new information an experimenter gets from an experiment?
What are DATA or RESULTS or FINDINGS?
This is the way to write Force equals Mass times Acceleration as an equation
What is F=ma or F=m*a?
What is a PARTIAL ECLIPSE?
The seasons when the earth's axis is inbetween WINTER and SUMMER
What are SPRING and FALL?
This is the hemisphere the North Pole is in
What is the NORTHERN HEMISPHERE?
