In this activity, learners will build a ball run contraption. Marble Machines are made from familiar materials, designed to send a rolling marble through tubes and funnels, across tracks and bumpers, and into a catch at the end. The larger the variety of materials available, the more creative innovation is possible! This activity works well as an individual activity, or in groups of two.
