Mars, the fourth planet from the Sun, is famed for its towering Olympus Mons, vast Valles Marineris canyon, and the tallest volcano in the solar system. Crafting a papier‑mâché model helps students visualize these features and deepens their understanding of planetary geology.
Step‑by‑Step Instructions
- Inflate a red balloon until it measures approximately 11 cm in diameter.
- In a plastic container, mix two parts white glue with one part warm water. Stir until the solution is smooth and homogeneous.
- Dip newspaper strips into the glue mixture and apply them to the balloon—one strip at a time—until the balloon is completely covered. Repeat this coating process two more times to create three paper‑mâché layers. Allow the structure to dry overnight.
- Use a needle to carefully puncture and deflate the balloon.
- Paint the entire papier‑mâché globe a uniform red base color. Let it dry fully.
- Using reference maps of Mars, add topographical details—mountains, valleys, and volcanoes—by painting in shades of black, brown, and other contrasting colors.
Materials Needed
- Red balloons
- White glue (e.g., PVA)
- Warm water
- Plastic containers for mixing
- Strips of newspaper
- Poster paint (red, black, brown, etc.)
- Paintbrushes
Quick Tips
Add a string to the top of each finished globe so students can hang their models—an easy way to display their work in the classroom.
Safety Notice
Use extra newspaper on desks to minimize cleanup. Students should wear smocks or old clothing to protect against glue and paint stains.
