01
Unit 1: Our Solar System
Map the Sun, planets, moons, and smaller objects.
Solar System Map
The Sun is the center of our solar system.
Open LessonPlanet Order
Planets can be identified by their order from the Sun.
Open LessonSpace Distances
Space is much larger than classroom models can show.
Open Lesson
02
Unit 2: Earth, Sun, and Moon
Explain day, night, shadows, seasons, and Moon phases.
Day and Night
Earth spins once each day.
Open LessonMoon Phases
The Moon looks different because we see different sunlit parts.
Open LessonShadows and Seasons
Sunlight angle changes shadows and helps explain seasons.
Open Lesson
03
Unit 3: Planet Detectives
Compare planets by surface, atmosphere, size, and clues.
Rocky Planets
The inner planets have solid surfaces.
Open LessonGiant Planets
The outer planets are large, cold, and far from the Sun.
Open LessonPlanet Clues
Scientists use evidence to identify planets.
Open Lesson
04
Unit 4: Stars and Sky
Learn why stars shine and how sky patterns help observers.
Stars and the Sun
The Sun is the closest star to Earth.
Open LessonConstellations
Constellations are star patterns people named.
Open LessonSafe Sky Observing
Observe the sky safely and carefully.
Open Lesson
05
Unit 5: Space Tools and Missions
Discover telescopes, satellites, probes, rockets, and rovers.
Telescopes
Telescopes collect light to help us see faraway objects.
Open LessonSatellites and Probes
Spacecraft collect information from orbit and deep space.
Open LessonRovers and Rockets
Rockets launch missions, and rovers explore surfaces.
Open Lesson
06
Unit 6: Review and Space Scientist Skills
Use models, evidence, and communication like a scientist.
Science Models
Models help explain things that are too large, small, far, or slow to observe directly.
Open LessonSpace Report
A good science report uses evidence and clear labels.
Open LessonFinal Review
Review the whole course before the final exam.
Open Lesson
07
Unit 7: Space Data Lab
Read simple data, graphs, and evidence from space missions.
Moon Data Patterns
Moon observations form patterns that can be recorded and compared.
Open LessonOrbit Graph
Graphs help compare planet distances and orbit times.
Open LessonSpace Claim and Evidence
Science explanations connect a claim to evidence and reasoning.
Open Lesson
08
Unit 8: Earth From Space
Use satellites to study weather, water, land, and change.
Weather From Space
Weather satellites help people observe clouds, storms, and patterns.
Open LessonWater From Space
Space images help scientists track water on Earth.
Open LessonEarth Change From Space
Comparing images helps scientists notice change over time.
Open Lesson
09
Unit 9: Mission Engineering
Plan spacecraft with goals, constraints, tests, and teamwork.
Design a Rover
Rover parts are chosen to solve a mission problem.
Open LessonSatellite Design
Satellites need power, instruments, communication, and a stable orbit.
Open LessonMission Budget
A mission plan balances choices with limited resources.
Open Lesson
10
Unit 10: Deep Space and Careers
Explore galaxies, exoplanets, and space science careers.
Galaxy Map
A galaxy is a huge group of stars, gas, dust, and dark matter.
Open LessonExoplanet Hunt
Scientists find planets around other stars by looking for evidence.
Open LessonSpace Careers
Space work needs many skills, not only astronauts.
