Build a model water catchment

The activity Building a model water catchment provides students with a three-dimensional experience of water catchments. Students can build a large outdoor model or smaller catchments using tote trays.

The activity provides a useful context in which to discuss models in science – why scientists use them, the similarities and differences between the model and a real catchment and the benefits and drawbacks of using a model.
