Connecting Motion to Scientific Theory: Presentation Walkthrough

Section role: supports the formalization of student discoveries in Section 3 while the teacher guides the class discussion from hands-on lab findings to scientific concepts. Slides: (1) Title — 'Forces, Work, and Mass'; (2) Turning Forces — bullets: twisting a soda bottle lid, examples of rotational force in daily life; (3) The Scientific Definition of Work — bullets: work requires motion, riding a bicycle vs. pushing a heavy brick wall; (4) Mass in Action — connection back to the coin and heavy book lab from Section 2, showing greater mass requires greater force; (5) Contact Forces — bullets: friction, air resistance, and physical touch; (6) Non-Contact Forces — bullets: gravity pulling objects down, magnetism pulling iron; (7) Mass vs. Weight — definitions in 5th-grade terms; (8) Closing slide — 'When you push a wall and it does not move, have you done work?' — hands control back to the teacher to set up the Section 4 mission check.
