In physical science, third graders explore the properties of light and color. Worksheets introduce key concepts like how objects appear a certain color depending on how they reflect and absorb light, and how materials interact with light to appear transparent, translucent, or opaque. Additional materials focus on forms of energy, including sound, heat, light, electrical, and motion energy, helping students connect energy concepts to real-life situations and scientific principles. Life and Earth science activities guide students through topics like habitats, fossils, and rock classification. Worksheets such as Habitat Highlights: Desert Plants help students compare desert adaptations, analyze diagrams, and infer survival strategies. Investigative lessons like Exploring Fossils: Clues from the Past teach the differences between body and trace fossils and help students make evidence-based inferences. Learners also practice identifying igneous, sedimentary, and metamorphic rocks, developing observation and classification skills. In space science, students explore the solar system through interactive worksheets like Planets in Our Solar System, where they label planets and learn interesting facts about each one. To build digital literacy, the collection includes typing games that help students practice writing complete sentences and paragraphs.

All materials are available in both digital and print-friendly formats, supporting a range of learning styles. Use our easy filters to find the right third grade science worksheets for introducing new topics, reinforcing lessons, or preventing learning loss. Ready to keep exploring?
