Puzzled by ETS?

Article excerpt

Engineering, Technology, and Applications of Science (ETS) is one of the Disciplinary Core Ideas in the K-12 Framework. Use our puzzle to review the similarities, differences, and interconnectedness of science and engineering. Consult chapters 3 and 8 in the Framework for help. Good luck!
