Hello,
You just learned about rockets, planets, satellites, astronauts, ISRO, NASA, and the mysteries of our universe.
Now it’s your turn to explore.
In this challenge, you become a scientist, an engineer, an artist, and a storyteller all at once. Your mission is to build a mini Solar System museum exhibit and share something amazing about space.
This page is your mission control. Forgot the instructions? Need ideas? Have a question? Everything you need is right here.
And remember: science starts with curiosity. Ask questions. Be brave. Have fun!
Your Mission: Build a Mini Solar System Museum Exhibit
Build a tabletop model of our Solar System that teaches others about the planets and how humans explore space.
βοΈ 1. The Sun and Eight Planets
Put them in the correct order from the Sun:
- The Sun
- Mercury
- Venus
- Earth
- Mars
- Jupiter
- Saturn
- Uranus
- Neptune
πͺ 2. Planet Labels
Every planet needs a clear label so judges know which is which. You can use:
- Small paper flags
- Cardboard signs
- Popsicle sticks
- Printed names
- Your own creative decorations
π 3. One Amazing Fact About Each Planet
Every planet needs one interesting fact β about its size, temperature, moons, weather, exploration missions, or special features.
| Planet | Example Fact |
| Mercury | The speed champion zooms around the Sun in just 88 days! |
| Venus | The hottest planet hot enough to melt lead (about 465Β°C). |
| Earth | The only planet we know that has life and liquid water on its surface. |
| Mars | Home to Olympus Mons, a volcano 3 times taller than Mount Everest! |
| Jupiter | The giant so big that over 1,300 Earths could fit inside it. |
| Saturn | Its stunning rings are made mostly of ice and rock. |
| Uranus | The oddball it spins on its side, like a rolling ball. |
| Neptune | The wind champion β its winds can blow faster than 2,000 km/h! |
These are only examples find your own facts too.
π 4. Add a Space Technology Connection
Space exploration is also about the amazing technology humans build. Include one space technology object, such as:
- π A rocket
- π°οΈ A satellite
- π A telescope
- π€ A Mars rover
- π¨βπ An astronaut
- π A Moon lander
Think like an engineer: How would humans explore this world?

Your Two-Week Mission Timeline
| Days | Phase | What to Do |
| Days 1β2 | Research | Learn about each planet. Choose one fact for each. Decide your technology object. |
| Days 3β5 | Planning | Plan your layout, materials, and what makes yours unique. |
| Days 6β10 | Building | Make the Sun, all eight planets, labels, fact cards, and your technology object. |
| Days 11β12 | Explaining | Practice explaining your favorite planet and why you designed it this way. |
| Days 13β14 | Final Prep | Check labels, confirm facts, add final details, prepare your explanation. |
Scientists and engineers always plan before they build and a great scientist explains their work not just makes it.

β FAQ
Can I work with a friend?
Yes alone or in pairs if your teacher allows it.
Do I need expensive materials?
No! Simple, free, and recycled materials are encouraged. Use what you have at home.
