Students complete nine fill-in-the-blank problems about Mercury's orbit length, Olympus Mons on Mars, and Saturn's density. The matching activity pairs Mercury, Venus, Jupiter, and Saturn with their distinctive features — rings, storm, temperature record, and extreme temperature swings.
Matching each planet to its most distinctive feature — rings, storm, temperature record, or extreme conditions — consolidates planet-by-planet knowledge into a memorable set of identifiers for each world.
Style:
Solar System
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Mercury takes about 88 Earth days to complete one orbit around the Sun.
2. The largest volcano in the solar system, Olympus Mons, is found on Mars.
3. Saturn is the least dense planet and could theoretically float on water.
4. Venus rotates in the opposite direction from most planets, which is called retrograde rotation.
5. Jupiter's Great Red Spot is a massive storm that has raged for hundreds of years.
6. Neptune appears blue in color because methane in its atmosphere absorbs red light.
7. Uranus is tilted on its side at about 98 degrees, making its seasons extreme.
8. Earth's protective atmosphere shields living things from harmful radiation from the Sun.
9. Mars has two small moons named Phobos and Deimos.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
