4th Grade Science Worksheets

In the upper elementary grades, science becomes more systematic. Children plan fair tests that change one thing at a time, measure, and explain results with evidence. Topics span forces and motion, energy, life cycles and ecosystems, rocks, water and weather, and the solar system, with models and diagrams for what can't be seen directly. Fourth grade science studies energy and waves, how plant and animal structures work, and how rocks, erosion and earthquakes shape the Earth. Download any of these fourth grade science worksheets free as a PDF, at easy, medium and hard levels, many with an answer key for grown-ups.
