Physics - Grade 9

This three-week Main Lesson introduces the students to the basic phenomena and laws of pressure-related phenomena (heat = thermodynamics, air = acoustics, water = hydraulics). Through demonstrations the students observe and then derive the fundamental laws of air pressure, fluid pressure, waves, and sound and then proceed to an exploration and understanding of the steam engine and internal combustion engine. During this course, students are required to take careful notes, draw demonstrations, sum up key ideas, and disassemble and reassemble one or more internal combustion engines.
