Sand, Plants and Pants

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties. Learners investigate the hydrophobic properties of plants, nano-fabric pants and magic sand.

Materials List (per group of students)

  • Assortment of hydrophobic plant leaves, such as lotus leaves, nasturtium leaves, mustard greens, leafy kale, broccoli, or Chinese cabbage and an assortment of non-hydrophobic plants (iceberg lettuce, etc.). At minimum, 4-5 TOTAL leaves (note that more leaves will extend the length of the program)
  • Trays for plants
  • Beaker of Water
  • 1 cup of cocoa mix and spoon or small strainer
  • 1 Beaker filled with a purple liquid (water with food coloring will come out in the wash)
  • Swatch of non-treated fabric
  • Swatch of nano-treated fabric (search online for “stain resistant pants,” then check for the word “nano” in the garment description)
  • Miniature Pants made of nanotechnology stain-resistant fabric (search online for “stain resistant pants,” then check for the word “nano” in the garment description)
  • Regular-sized nano pants (search online for “stain resistant pants,” then check for the word “nano” in the garment description)
  • Water guns filled with purple liquid (to resemble grape juice) - optional
  • Tray and hanger for miniature and regular-sized Nano Pants, respectively
  • Magic Sand®
  • Regular Sand
  • Demo Tank, small aquarium, or large bowl
