A. LESSON PREVIEW/REVIEW
1) Introduction (2 mins)
Welcome our dear students to our new lesson for this day. We will deal with Nanotechnology. How small is nano-
small? We will continue to explore the effect of technology as we were done discussing about Information Age
during our previous meetings. Stay connected!
B.MAIN LESSON
1) Activity 1: Content Notes (13 mins)
Nanotechnology is the convergence of science, technology, and engineering where the observation,
characterization, design, and controlled fabrication of materials and devices are at the scale of less than 100 nanometers (1
nanometer = 10-9 m). The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s
Plenty of Room at the Bottom” by physicist Richard Feynman (the father of nanotechnology) at an American Physical
Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, long before the term
nanotechnology was used. In his talk, Feynman described a process in which scientists would be able to manipulate and
control individual atoms and molecules. Over a decade later, in his explorations of ultraprecision machining, Professor
Norio Taniguchi coined the term nanotechnology. It wasn't until 1981, with the development of the scanning tunneling
microscope that could "see" individual atoms, that modern nanotechnology began. There are two fundamental approaches
to NANOMANUFACTURING:
1. Bottom-up fabrication – it manufactures products by building them up from atomic- and molecular-scale components.
However, this method can be time-consuming. Scientists and engineers are still in search for effective ways of putting
up together molecular components that self-assemble and from the bottom-up
organized structures.

2. Top-down fabrication – it trims down large pieces of materials into nanoscale. This process needs larger amounts of
materials and discards excess raw materials.
