Solar System
This is the star at the center of our solar system.
What is the Sun?
This force pulls objects toward each other.
What is gravity?
This object in space gives off its own light.
What is the Sun?
This technology orbits Earth and collects data.
What are satellites?
Astronauts live and work in this place while in space.
Astronauts live and work in this place while in space.
These are large rocky or gas bodies that orbit the Sun.
What are planets?
This changes depending on gravity: mass or weight?
What is weight?
The Moon is visible because it does this with sunlight.
What is reflect light?
This technology allows astronauts to travel to space.
What are rockets?
Name ONE challenge astronauts face in space.
Isolation / no gravity / limited space
This object orbits a planet (like the Moon orbits Earth).
What is a natural satellite?
Why would you weigh less on the Moon?
What is less gravity?
Give ONE example of something that reflects light in space.
Moon / planets
Give ONE way satellites help Earth.
Weather tracking / climate monitoring
How do astronauts stay healthy in space?
Exercise / healthy food
These are small rocky objects mostly found between Mars and Jupiter.
What are asteroids?
This movement of Earth causes day and night.
What is rotation?
Stars are visible because they do this.
What is emit light?
This tool lets scientists see far into space.
What is a telescope?
Give ONE benefit of space exploration.
New technology / learning about Earth
Describe ONE difference between a comet and an asteroid.
Comets have ice and tails; asteroids are mostly rock
A ball weighs 10 N on Earth. On the Moon, it weighs less. Explain why its weight changes but its mass stays the same.
Mass stays the same because the amount of matter doesn’t change. Weight changes because gravity is weaker on the Moon.
Explain the difference between emitting and reflecting light.
Emitting = making light; reflecting = bouncing light.
Explain what the Canadarm does AND why it is important for space missions.
The Canadarm is a robotic arm used on spacecraft and the International Space Station. It helps move equipment, repair satellites, and assist astronauts during spacewalks. It is important because it makes space work safer and more efficient.
Give ONE negative impact of space exploration
Cost / pollution / space debris
