Explain It
Explain why we can see the Moon
It reflects sunlight
If the Sun disappeared, what would happen first?
Darkness
Compare a meteor and meteorite
Atmosphere vs surface
Why do scientists track meteors?
For our safety and survival
What tool would you send to Jupiter? Why?
Probe / satellite that can orbit it since it has no surface
Explain what happens when a meteoroid enters Earth’s atmosphere
Burns → meteor
What happens to orbit if gravity increases?
Tighter orbit
Compare rover vs satellite
Surface vs orbit
Why are satellites important for weather?
Data collection
What can a satellite help us with?
Tracking weather / communication
Explain how satellites help us daily
GPS, communication
If the Sun disintegrated, what happens to Earth?
Life is lost
Compare Earth vs Moon gravity
Earth's gravity is stronger
Why can’t humans live on gas giants?
No solid surface
What do you call the largest telescope in space? What has it done so far?
The Hubble Telescope has determined the universe's age (13.8 billion years), confirmed the accelerating expansion of the universe, and identified supermassive black holes at the center of most galaxies.
Explain why gravity is essential for life on Earth
Holds atmosphere, keeps orbit
If a meteor reaches the surface of the Earth, what is it called?
Meteorite
Which is better for exploring distant galaxies: rover or telescope? Why?
Telescope
What problem would occur if satellites stopped working?
GPS/communication loss
How long do astronauts spend in the International Space Station? What is one challenge that they face?
Up to 6 months
Explain how light helps scientists understand space
Reflection/emission reveals objects
If a planet reflects no light, can we see it? Why?
No — needs reflected light
Which is more important: gravity or light? Justify.
Both!
How could a meteor impact affect Earth?
Damage, climate effects
You discover a new celestial body. How would you know if it is a planet or dwarf planet?
