8th 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 eighth grade programs focus on physical science: atoms and chemical reactions, forces and motion, energy and waves. These eighth grade science worksheets are free printable PDFs at easy, medium and hard levels, good for homework practice or review, many with answer keys.
