No Prep Sub Plans – Solar System: Inner Planets | STEM Design Series: (4th-8th)

STEM Design Series: No Prep Sub Plans – Solar System: Inner Planets | Scale Model Project (Grades 4–8)
Looking for an engaging space + STEM lesson that helps students understand how our closest planetary neighbors compare?
In this STEM Design Series: Research + Group Project, students explore Mercury, Venus, Earth, and Mars and design a proportional scale model to show their relative sizes and distances from the Sun. This hands-on challenge builds deep understanding of planetary differences and the concept of scale.
What Students Will Do:
- Research the inner (terrestrial) planets
- Compare key features (surface conditions, atmospheres, temperature)
- Investigate why each planet is so different
- Analyze distances from the Sun and relative planet sizes
- Choose a scale for size and distance
- Design a proportional scale model layout
- Create a “wow” comparison to show scale
- Present their model and explain what surprised them
What’s Included:
- ✔️ Teacher Directions (clear, simple, and easy to implement)
- ✔️ Student Research Page
- ✔️ Student Planning / Scale Model Organizer
- ✔️ Black & White versions of all student pages (printer-friendly)
STEM Skills & Concepts Covered:
- Scale and proportional reasoning
- Astronomy & planetary science
- Comparing planetary environments
- Data interpretation (size and distance)
- Problem-solving & critical thinking
- Visual modeling and design
Perfect For:
- Sub plans (Print & Go – no prep required!)
- Space or astronomy units
- STEM/STEAM lessons
- Project-based learning (PBL)
- Cross-curricular math + science integration
Why Teachers Love It:
- Makes abstract space concepts concrete and visual
- Strong connection to math (scale & proportion)
- Encourages comparison and deeper thinking
- Works for independent or sub-led instruction
- Easy to implement with minimal prep
