A design for a new, inexpensive tidal simulation unit enables researchers to investigate tidal marsh plant growth in a controlled setting. The unit costs less than US$27 to build, takes up less than two square feet of space, and does not require external plumbing; the protocol is now available. The system could be an important tool for researchers working to preserve and restore environmentally important wetlands.
Perhaps a similar sort of simulation unit could be the basis of practical enquiries in schools?
