# Nanotechnology - Small Things Bring Big Change

Scientists have discovered that materials at the nanoscale, measured in billionths of a meter, behave differently than at the macroscale. In this session, students will learn about the size of a nanometer and how properties can be varied by making changes at the nanoscale.

Vocabulary: Nanometer, order of magnitude, nanotechnology, carbon allotropes (diamond, graphite, graphene, nanotube, buckminsterfullerene), conductor, index of refraction, thin film, light interference

Session Information:

• Flexible instruction whether students are in the classroom or at home.
• Interactive, instructor-led session facilitated with students using materials from school or home.  Can also be demonstration-based if students do not have access to materials.
• Teachers will receive a detailed Teacher Notes guide upon booking.
• Secure link to ZoomGov videoconferencing platform will be provided.
• \$360 (BOCES-aidable)
• Time: 90 minutes

Standard 4, 1 Follow safety procedures in the classroom and laboratory.

Standard 4, 2 Safely and accurately use the following tool: metric ruler.

Standard 4, 3 Use appropriate units for measured or calculated values.

Physical Setting Skills, 15 Determine the electrical conductivity of a material using a simple circuit.

Standard 1, M1.1c Apply mathematical equations to describe relationships among variables in the natural world.

Standard 1, S2.1a Demonstrate appropriate safety techniques.

Standard 1, S2.1b Conduct an experiment design by others.

Standard 1, S2.1d Use appropriate tools and conventional techniques to solve problems about the natural world, including: measuring, observing, describing.

Standard 1, T1.3a Generate ideas for alternative solutions.

Standard 1, T1.2b Evaluate alternatives based on the constraints of design.

Standard 6, 2.2 Use models to study processes that cannot be studied directly (e.g., when the real process is too slow, too fast, or too dangerous for direct observation).

Standard 6, 3.2 Use powers of ten notation to represent very small and very large numbers.

3.1a Substances have characteristic properties. Some of these properties include color, odor, hardness, and boiling and freezing points.

3.1h Density can be described as the amount of matter that is in a given amount of space.

3.3a All matter is made up of atoms. Atoms are far too small to see with a light microscope.

3.3c Atoms may join together in well-defined molecules or may be arranged in regular geometric patterns.

4.4b Light passes through some materials, sometimes refracting in the process. Materials absorb and reflect light, and may transmit light.

4.4e Electrical circuits provide a means of transferring electrical energy.
