Play "Would You Rather" with your physical science class as an anticipatory set. Each game question is related to the pressure put on an area of the body. Let this activate a discussion on forces, pressure, and area. Give your class Newton's second law of motion and the formula F=ma. With the concept in mind, your class will explore pressure using a variety of hands-on materials. Finally, they apply their learning to the real-world scenario of deep-sea diving. A video about James Cameron's ocean exploration, handouts, detailed teacher's notes and background information, and a link to an online mapmaking activity combine for a richly detailed lesson plan!
