This outdoor activity (on page 2 of the PDF) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing there. Groups of learners will scout at least two locations in a sandy area, count the number and types of plants in contact with a 10 meter line, and then sample the moisture in the top 30 cm of sand in each location, graphing their results to analyze their data. Relates to linked video, DragonflyTV: Sand Dunes.
