Lesson Plans
Grades 3–645–60 minutes
Scale of the Solar System
Students build a scale model of the solar system using everyday objects to understand the enormous distances between planets. This hands-on activity connects mathematics (ratios and proportions) with space science.
Grades 4–740–50 minutes
Why Is Mars Red?
Students investigate why Mars appears red by conducting a simple rust experiment with steel wool and vinegar. They connect the chemical process of oxidation to the iron-rich Martian surface.
Grades 2–530–45 minutes
Phases of the Moon
Students use a lamp and a ball to model the phases of the Moon, learning why we see different shapes throughout the month. They keep a Moon journal to track real observations over two weeks.
