6th Grade Science Worksheets

Middle school science goes deeper into the physical, life and Earth sciences. Students model matter as particles, study chemical reactions, forces, energy and waves, explore cells, genetics and ecosystems, and investigate plate tectonics, weather and climate. Designing investigations and analyzing data matter as much as learning facts. Many sixth grade programs start with Earth and space science: the water cycle, weather, plate tectonics and the solar system. These sixth grade science worksheets are free printable PDFs at easy, medium and hard levels, good for homework practice or review, many with answer keys.
