Models in Science
A copy of a real object that is built to look like the real one. It can be smaller, larger, or the same size.
What is a physical model?
An imaginary line about which an object rotates around and around
What is an axis?
Caused by the Earth’s tilt and orbit around the Sun. 4 times in the year marked by similar weather patterns and daylight hours.
What are seasons?
A celestial body moving in an elliptical orbit around a star and is larger than a moon.
What is a planet?
The first planet from the sun.
What is Mercury?
Using graphs, charts, or other visual representations to simplify data.
What is a graphical model?
Leans to one side, and doesn’t sit straight up. The angle between the rotating axis and the north pole of a planet if it was straight up,
What is an axial tilt?
The force by which a moon, planet or sun draws objects towards its center. Due to an object’s mass.
What is a gravitational pull?
The celestial bodies that orbit around planets.
The second planet from the sun.
What is Venus?
The number used to multiply the dimensions of one object to get an object that looks the same but is larger or smaller than the original.
What are scale properties?
A regular, repeating path that an object in space takes around another one.
What is an orbit?
A sun’s gravitational pull causes objects to orbit around it (planets, moons, asteroids) creating this
What is a solar system?
The phases of the moon caused by the changing positions of the Moon, Earth, and the Sun.
What are lunar phases?
The third planet from the sun.
What is the Earth?
A way of describing and representing a real-world system to make it easier to understand.
What is a conceptual model?
The distance from an object in space to the body which it is orbiting around.
What is an orbital radius?
HUGE collection of solar systems, gas, and dust that are held together by gravity.
What is a galaxy?
The blocking of light from one celestial (space) object that goes between the sun and an observer.
What is an eclipse?
The fourth planet from the sun.
What is Mars?
Happening in cycles. Repeating over and over again.
The shape of an ellipse, which is an elongated circle stretched into an oval.
What is an elliptical?
A HUGE spiral system of several hundreds of billions of stars, one of them is our sun. It’s the galaxy we live in.
What is the Milky Way Galaxy?
Small, rocky objects that orbit around the Sun.
What are asteroids?
The fifth planet from the sun.
What is Jupiter?
