Item # P1-2080
This nanotechnology STEM kit gives your students the opportunity to apply revolutionary manufacturing technique to grow nano-scale and micro-scale copper wires.
|Activity 1 - Making a Wire Lithograph|
(GUIDED – MODEL EXPERIMENT)
Students incorporate the UNCD electrode in a traditional electroplating apparatus and apply a 9V potential to electroplate star wire patterns. Dependinguponelectroplating time (minutes), students create and transfer invisible (nanoscale) or visible (microscale) wires in a star pattern onto sticky tape. In the process, they learn directly about scale (nano to macro) scale perspective.
Your students observe these wire patterns placed on microscope slides under low (<100X) magnification. They assess how electroplating time (electrodeposition) affects wire length (and corresponding wire pattern visibility) and how wire patterns can be consistently produced and reliably transferred onto a flexible support medium (sticky tape).
These learned skills form the basis for future student design applications – such as incorporating copper wire lithographs into sensors or creating light diffraction gratings.
|Activity 2 - Making a Conductive Pressure Sensor|
(GUIDED – INQUIRY EXPERIMENT)
Students apply their knowledge of nanomanufacturing (E&L) to create nanowire and microwire patterns that can be used to create a pressure sensor.
Students learn what a sensor is and use their observational electro-deposition data (from the previous activity) to design, manufacture, and test a conductive ‘bridge’ (pressure ‘sensor’) allowing illumination of a 9V LED lamp
Nanotechnology Kit Concepts
Developed in partnership with Argonne National Laboratory, this kit gives your students the opportunity to apply a revolutionary nanotechnology manufacturing technique to grow nano-scale and micro-scale copper wires. Using a unique ultra-nanocrystalline diamond (UNCD) electrode, students use traditional electroplating and lithography (E&L) techniques to grow pattern-shaped wires that become the essential components that can be used to fabricate optical and electrical sensors and other devices.
This kit covers the following concepts:
Designed for use by 40 students working in groups of 4.
