Craters and Science Skills
During a laboratory investigation, a student spills an unknown chemical. This should be the student's first action.
Tell the teacher
This is the galaxy that contains our Solar System.
Milky Way Galaxy
This region around a star may have temperatures suitable for liquid water to exist on a planet's surface.
What is the Goldilocks zone, or habitable zone?
A student changes the height from which a ball is dropped. The drop height is this type of variable.
Independent variable
This unit is approximately the average distance between Earth and the Sun.
Astronomical Unit
If Earth were moved near Neptune's current distance from the Sun, Earth would receive much less of this
Solar energy
Earth has fewer easily visible ancient impact craters than Mercury because processes like these gradually change Earth's surface.
weathering, erosion, vegetation, and other surface processes?
Despite its name, a light-year measures this rather than time.
Distance
A rocky planet with moderate temperatures, a stable atmosphere, and possible liquid water would be considered a stronger candidate for this.
Earth-like or potentially habitable conditions?
When a meteorite crashes into the surface of a planet or moon, it can create this bowl-shaped feature.
Impact Crater
The Sun is not located at the center of the Milky Way. Instead, the Sun does this
Orbit the milky way
If Earth suddenly lost its atmosphere, more small meteoroids could do this instead of burning up or breaking apart high above the surface.
Reach Earth's surface?
Students increase drop height from 0.5 m to 2.0 m and crater diameter increases from 4 cm to 10 cm. This conclusion is best supported.
greater drop height was associated with larger crater diameter?
This massive collection can contain billions of stars, along with gas, dust, planets, and other objects held together by gravity.
Galaxy
A young star system has rocky worlds close to its star and gas- and ice-rich planets farther away. This difference occurred mainly because the inner and outer regions had different amounts of this
Heat, or different temperatures?
