(i) The lesson plan is for a 6th grade science class about investigating force and energy through analyzing friction. It involves showing students videos and pictures to understand friction's advantages like staying stationary and disadvantages like wearing things out. (ii) Students will do activities like observing a ball not moving on a table due to friction, an eraser wearing out, and the difficulty of pushing a heavy object. They will also list friction's advantages and disadvantages. (iii) The lesson concludes by having students summarize in their worksheets and mind maps what they learned about friction's advantages like walking without slipping and disadvantages like the need for more effort to move objects.
