4. Formation of the Solar System Reading Comprehension
To help students explore planetary formation, this reading comprehension activity walks them through the nebular theory and the step-by-step process of how our solar system came to be. This is a great addition to your solar system activities, reinforcing key concepts while building reading comprehension and critical thinking skills.
This formation of the solar system reading comprehension is a guided reading, meaning that the content is chunked with short questions between each subtopic. The reading is accompanied by 2 pages of practice questions.
Formation of the Solar System Topics:
✔ Nebular theory and solar nebulae
✔ Protostars, protoplanetary disks, and planetesimals
✔ Inner and outer planet formation
✔ Characteristics of the inner and outer planets
By incorporating this reading-based approach into your solar system activities, students will gain a strong foundation in planetary formation while improving their analytical and comprehension skills!

5. Alien Life Hypothesis Challenge: A Cosmic STEM Adventure
Are we alone in the universe? Spark curiosity and critical thinking in your students with this Alien Life Hypothesis Challenge, one of the most engaging solar system activities! This STEM-based exploration encourages students to research real exoplanets and design a hypothetical alien species that could survive in an extreme extraterrestrial environment.
How to Implement This Mission Challenge:
1. Assign an Exoplanet – Have students select a real exoplanet using websites like NASA Exoplanet Archive or Exoplanet Exploration.
2. Investigate Planetary Conditions – Students analyze the temperature, atmosphere, gravity, and distance from its star to determine habitability.
3. Create an Alien Life Form – Based on their research, students design an alien species adapted to the planet’s unique conditions.
4. Present the Alien – Students can draw their creature, create a digital slideshow, or write a “discovery report” detailing its adaptations.
5. Showcase Their Work – Organize a gallery walk or compile designs into a classroom “Galactic Bestiary”!
This hands-on approach to solar system activities blends science, creativity, and problem-solving, making it an engaging, cross-disciplinary lesson that students will love!
6. STEM Mission: Design a Mars Rover for Exploration
Looking for hands-on solar system activities that engage students in engineering and space exploration? The STEM Mission: Design and Create a Rover to Explore Mars is the perfect way to challenge students to think like NASA engineers while reinforcing space science concepts!
Mission Objective:
After reading the included background reading about conditions on Mars, student will follow a mission directive to design and build a manned Mars rover (on paper) that can withstand the harsh Martian environment and assist scientists in collecting data. Using a combination of over 70 included clip arts, hand-drawn components, or even cutouts from magazines, students will construct a customized Mars rover equipped with four scientific instruments for planetary research.
After completing their rover, students will answer five mission follow-up questions, explaining how their design supports safe exploration and data collection on Mars. With clear step-by-step directions and a detailed rubric, this project is student-led and easy to implement!
I like to display my students’ designs in a gallery walk or have students present their rovers. It’s also fun to host a “Best Mars Rover” contest. This make an excellent group project!
So Easy to Implement!
✔ Engaging, hands-on learning that integrates STEM and space exploration
✔ Easy prep—just print and go! Minimal supplies needed (scissors, glue, paper, colored pencils)
✔ Flexible use: Works as a standalone STEM challenge, space enrichment lesson, or even a sub-plan
This activity has everything you need to bring space exploration and engineering into your classroom. The teacher lesson plan covers standards, objectives, pacing, and materials, while the student handout provides background information, a step-by-step procedure, and analysis questions. A rubric is included for easy assessment. Perfect for astronomy lessons, STEM challenges, or cross-disciplinary activities, this Mars Rover Challenge fosters critical thinking, creativity, and hands-on learning in an exciting way!
7. Build a Scale Model of the Solar System
One of the best ways to help students visualize the vastness of space is through a hands-on activity that allows them to construct a scale model of the solar system. The Exploratorium’s Build a Scale Model of the Solar System activity is a fantastic resource for demonstrating the relative sizes and distances of planets in a way that makes space science more tangible.
Using this activity, students will first calculate a scale to represent the enormous distances between planets. They can use grains of sand, marbles, or sports balls to model each celestial body. After determining their scale, they will map out the solar system, measuring distances and positioning planets accordingly. This can be done in a classroom, hallway, or even outdoors for a more dramatic visual effect. Once the model is complete, students will compare their expectations with reality, leading to discussions about why planetary distances vary so much and how this affects space exploration.
This activity is a great addition to your solar system activities, as it provides a meaningful, interactive approach to understanding astronomical distances. With minimal materials and easy setup, it’s an engaging way to reinforce key concepts in planetary science while making learning fun and memorable. Whether you’re introducing the solar system or reviewing planetary relationships, this model-building activity is sure to captivate your students.
Final Space Thoughts
Teaching the solar system is already a blast (pun intended), but adding interactive, hands-on solar system activities makes it even more out-of-this-world! Whether your students are designing rovers, discovering alien life, or planning their next space vacation, these solar system activities will keep them engaged and excited.
