Simple MachinesThe 15 lessons in this module introduce students to simple machines, including levers, wheels and axles, gears, pulleys, inclined planes, screws, and wedges. Students investigate how these simple machines work together in systems and use this knowledge to design and construct their own device containing a system of simple machines.Also included:materials lists activity descriptions questioning techniques activity centre and extension ideas assessment suggestions activity sheets and visuals The module offers a detailed introduction to the Hands-On Science program (guiding principles, implementation guidelines, an overview of the skills that young students use and develop during scientific inquiry), a list of children's books and websites related to the science topics introduced, and a classroom assessment plan with record-keeping templates. |
