Understanding Celestial Phenomena and Forces

Mumu Math and Science presents an educational course on Earth Science, focusing on astronomy. The course covers topics such as geocentric and heliocentric theories, the structure of the universe, planets, gravity, inertia, comets, asteroids, meteoroids, moon phases, eclipses, and Earth's seasons. Each video includes worksheets and activities for self-assessment. Upon completion, students will understand astronomical theories, differentiate between solar system, galaxy, and universe, and explain celestial phenomena. The course encourages kindness and offers resources for further learning.
