"Exploring Products - Nano Sand" is a hands-on activity exploring how water behaves differently when it comes in contact with nano sand and regular sand. Visitors learn about the hydrophobic properties of nano sand.
“Magic Sand” is a cart demo that demonstrates how changing nanoscale changes in a material can affect how that material behaves at the macroscale. Visitors learn that hydrophobic surfaces repel water and that “magic” sand repels water because of a nanoscale hydrophobic coating on the grains of sand. During the program, compare how magic sand and regular sand interact with water.
Purpose of the lesson is to: • Explore the properties of molecular bonding • Introduce students to the engineering of hydrophobic surface. • Demonstrate the concepts of hydrophobic and hydrophilic behavior.
These 'Do It Yourself' Nano activities and experiments allow families to experience and learn about nanoscale science, engineering, and technology at home or on the go! They are are designed to be done in the comfort of your own home. Each activity includes lists of widely available, inexpensive materials, step-by-step instructions, and detailed explanations.
