Overarching Concepts in GK-12: One Universe; Many Worlds

System Dynamics

System Dynamics

Time scales is a concept that scales with size. Thus, time scales in the nano world are measured in nanoseconds to minutes; while the time scales for ecosystems are in the range of hours, years, and decades. Nano: Fabrication or self-assembly of nano particles depend on: diffusion rates, dep... Read More

Self-Assembly - Organization of Complex Systems

Self-Assembly - Organization of Complex Systems

Bottom-up; Self-Assembly/Organization: Results from self-assembly/self organization of system that is controlled by the range, spatial orientation, range of interactions, and by the system’s dynamics. Top-Down: Result from the intervention of human technology and intelligence. The resultin... Read More

Size and Scale

The concept that unites the worlds of Nano and Environment under one Universe. Nano: will model the concept of size and scale in the atomic, molecular, and nanoscale. Environment: has several scales of observation: hectare (e.g. forest), ten meter scale (e.g. trees and large plants... Read More

Fractals

Fractals

Fractals: Is the geometry of nature resulting from bottom-up formation that under random conditions tend to produce fractal structures. In the environmental regime, a bottom-up formation always generates fractal geometries; this is not necessarily the case in the nano world. Nano: Self-a... Read More

Dominant Interactions-Forces

Dominant Interactions-Forces

  In the nano world, the rules of forces and interactions are very well defined; so is the strength of the force and its range. While in the environmental regime, the strength and range of interaction depend on abiotic and biotic factors. •magnitude of interactions-forces at the scale o... Read More

Surface to Volume Ratio

Surface to Volume Ratio

The Surface-to-Volume Ratio is important when the process is surface dependent; and the surface is the rate-limiting step (e.g. catalysis, drug delivery, respiration, absorption of water and nutrients). Nano: One of the most valuable properties of nanostructures is the enormous surface-to-volume... Read More

 

GK-12 Project

The GK-12 ProgramFrom Hectares to Nanometers: GK-12 Multidisciplinary Explorations of Tropical Ecosystems and Functional Nanoscienceis an interdisciplinary strategic partnership between the two largest and most developed research institutes of the University of Puerto Rico System: the Institute of Tropical Ecosystem Studies (ITES) and the Institute for Functional Nanomaterials. “One Universe, Many Worlds” is the unifying theme based by the comparison of the macro world with the nano world that will illustrate to our GK-12 Program fellow-teacher teams the recurring patterns in nature. The subject matter of these diverse fields spans 1011 orders of magnitude and to the untrained minds there seems to be no relation between them. This Program exploits this huge difference to introduce to the fellow-teacher teams “that the universe is a unified system” and that knowledge gained from studying one part can be applied to other scales and help understand what apparently seems to be very diverse worlds. It also increases the knowledge through multidisciplinary explorations of tropical ecosystems and functional nanoscience while improving fellows’ abilities to communicate and teach science.

The kernel of the project is the fellow-teacher teams.

The Resource Center for Science and Engineering (RCSE) of the University of Puerto Rico is one of the highest producers of Hispanic Ph.D. degrees in the nation and uniquely prepared to ensure that each year, 8 doctoral students in STEM fields will perfect their communication, teaching, team building, and collaboration skills as well as to improve in eight intermediate and superior level public schools teachers’ and students’ knowledge of and excitement about the multidisciplinary fields of nano and environmental sciences.
