Grade 3-5 students participate in activities that compare the properties of regular play sand to that of hydrophobic nano sand, observing the different effects water has on each and how nano has influenced each. They are then asked to formulate ideas on why hydrophobic sand is beneficial and in what ways it can be utilized to solve real world problems such as oil spills and water retention during farming. Teachers completing this workshop will be NEATEC certified to borrow the "Nano-Sand" module kit.
