Grade level
Grade 3 Science
Grade 3 science courses about forces, ecosystems, life cycles, traits, weather, and climate.
How to use this grade page
Grade 3 science focuses on observing patterns and explaining what students can see in the world around them. Students review forces and motion, animal groups, habitats, life cycles, inherited traits, weather, and climate. These courses and quizzes are useful for building early science reasoning with simple evidence.
Students can move between topic pages, course pages, and quizzes without losing the larger learning path. Course pages give lesson context, while quizzes provide quick practice and score tracking for logged-in users.
