Circling the planet
Concept 01
What is a Satellite?
A satellite is anything that orbits a larger body in space!
Natural Satellites
Made by Nature
These are celestial bodies that orbit planets without human help.
Prime Example:
The Moon
Earth's Moon takes about 27 days to travel all the way around us!
Artificial Satellites
Built by Humans
Machines launched into space on rockets to do special jobs.
Key Parts:
Solar Panels & Antennas
Panels catch sunlight for power; antennas send signals down to Earth!
Did You Know? Over 8,000 active human-made satellites are orbiting Earth right now!
Concept 02
How Do They Stay in Orbit?
The Perfect Cosmic Balance
Force 1
Super High Speed
Rockets boost satellites to speeds over 17,000 miles per hour, zooming sideways!
Fast forward push
Force 2
Earth's Gravity
Earth's invisible gravity pulls the satellite gently downward toward our planet.
Downward pull
The Result
An Orbit!
The satellite keeps falling around Earth's curve without ever hitting the ground!
Endless loop in space
Formula: High Forward Speed + Gravity Pull = Continuous Orbit!
Concept 03
Three Big Satellite Jobs
How they help us down on Earth
Weather Eyes
Track storm clouds, hurricanes, and wildfires from high above to keep communities safe.
Daily weather forecasts!
GPS & Maps
Send signals to phones and cars to show exactly where we are and give directions.
Never get lost!
Space Science
Space telescopes like Hubble snap crystal-clear photos of distant galaxies and planets.
Cosmic discoveries!

Reading Passage Read carefully, then answer the questions on Page 2
Look up into the night sky! You might see stars, clouds, and the glowing Moon. Did you know the Moon is a satellite ? A satellite is any object that travels around a larger object in space. The curved path it follows is called an orbit . Because nature placed the Moon in space, scientists call it a natural satellite .
Humans have also built thousands of their own machines to send into space. These are called artificial satellites . Powerful rockets launch them high above Earth's atmosphere. Satellites move extremely fast—over 17,000 miles per hour! Earth's gravity pulls them inward while their high speed pushes them forward. This perfect balance keeps satellites looping around our planet without crashing to the ground.
Artificial satellites have special parts to survive. Large, wing-shaped solar panels soak up sunlight to make electricity. Sensitive metal antennas send radio signals down to scientists on the ground. Satellites do many important jobs. Weather satellites track dangerous storms and hurricanes. Navigation satellites help GPS maps guide our family cars. Other satellites carry giant telescopes to photograph distant stars and colorful galaxies!

Student Exemplar Paragraph (Grade 3 Model) Title: High-Flying Helpers
[Intro/Hook] Did you know that thousands of high-tech machines are zooming through space right now? [Focus Statement] Satellites are amazing objects in orbit that help humans on Earth in many important ways. [Details] First, artificial satellites travel at super fast speeds of over 17,000 miles per hour, staying in a balanced loop around our planet called an orbit. Next, they soak up sunlight using solar panels to power their radio antennas. In addition, weather satellites track dangerous storms, while navigation satellites guide cars and ships using GPS maps. [Conclusion] In conclusion, satellites are incredible flying helpers that keep our world connected and safe every day.
