Materials World Modules

An Inquiry & Design-Based Science, Technology, Engineering, and Mathematics (STEM) Education Program

Mini Nanotechnology Module

Changing the Properties of Materials by
Amplifying the Nanoscale to the Macroscale

Design Project
Designing a Nanoscale Imaging Apparatus

Through the following key select activities, students discover that physical and chemical properties of materials can depend on their size, investigate how nanoparticles can be made, and determine how to amplify small features at the nano scale to the macroscopic scale. They are then challenged to design a working model of a nanoscale imaging apparatus or model a nanoscience phenomenon.

MWM will give students an opportunity to understand the world around them in a way they have never experienced before. The modules promote an awareness of the roles science and technology play in society and guide students to take increased control of their work.

Activity 1: Changing the Properties of Materials by Changing Their Size
The purpose of this activity is for students to discover that the physical and chemical properties of materials can depend on their size. In Part A students examine how the catalytic activity of manganese dioxide (MnO2) can be increased by reducing the size of the MnO2 particles. In Part B students use a colloid consisting of nanometer-sized gold particles to examine how the size of the gold particles in the colloid solution can be modulated and how this affects the optical properties (color) of the colloid. This color change is due to a physical change of the substance, not a chemical change.

Activity 4: Amplifying the Nanoscale to the Macroscale
In this activity students determine how to amplify the atomic scale to the macroscopic scale, a key feature of the atomic force microscope. They also learn about calibration and create a calibration curve by moving a cantilever on the millimeter scale and measuring its movement in the centimeter or decimeter scale.

Design Project 1: Designing a Nanoscale Imaging Apparatus
Students are challenged to build a nanometer-scale imaging apparatus using what they have learned in the previous activities.
