Activity 01
Small Groups: Model Road Construction
Provide trays with sand and sticks for old dirt roads, plus playdough or cardboard for modern tarmac bridges. Groups build paths, add toy vehicles or carts, and test for bumps or speed. They record one difference in a class chart.
What do you notice about how roads were built a long time ago?
Facilitation TipDuring Model Road Construction, circulate and ask each group to explain their choices of materials to uncover their thinking about strength and durability.
What to look forShow students two images: one of a historical road (e.g., Roman road, cobbled street) and one of a modern highway. Ask: 'What is one thing you notice that is different about these two roads?' Record their answers.
