Summary A structured bridge building activity, followed by a free-experimentation one. Science content Physics: Motion and Forces, Newton’s Laws, Gravity (K, 2, 6) Activities in this lesson Bridge building challenge Bridge shapes and forces Structure from triangles Procedure Start with the bridge challenge, to introduce the structural and fastener component of bridges, followed by the bridge structures to explore different shapes of bridges, ending with structures from triangles to reinforce how triangles can make a structure self supporting. Notes Champlain Heights Annex did Bridge Shapes and Forces, then Bridge Challenge. Tyee intermediates did Bridge Challenge then Bridge Shapes and Forces, and one division also did Structure from Triangles with sticky Q tips Tyee Ks did bridge shapes and forces (no graph) then Structure from triangles with toothpicks and marshmallows Shaughnessy 2s did Bridge building challenge then Bridge shapes and forces Grades taught Gr K Gr 1 Gr 2 Gr 3 Gr 4 Gr 5 Gr 6 Gr 7 Teaching Site Champlain Heights Annex Shaughnessy Elementary Tyee Elementary
