Overview

Exploring Size - Ball Sorter (NanoDays 2012)

Description:

"Exploring Size - Ball Sorter" is a hands-on activity in which visitors use sieves with different-sized holes, to sort balls by size. They learn that researchers are developing new technologies that can sort nano-sized things, including filters with nano-sized holes.

Objectives

Big Idea:

A nanometer is a billionth of a meter.

Learning goals:

A nanometer is a billionth of a meter.
New nanotechnologies include water filters with nano-sized pores and medications that use the human body’s natural filtration system.

NISE Net Content Map:

Nanometer-sized things are very small, and often behave differently than larger things do.

Nanoscience, nanotechnology, and nanoengineering lead to new knowledge and innovations that weren't possible before.

Nanotechnologies have costs, risks, and benefits that affect our lives in ways we cannot always predict.

Universal design:

Repeat and reinforce main ideas and concepts.

Provide multiple entry points and multiple ways of engagement

Provide physical and sensory access to all aspects of the program. Visitors can touch, see and hear different elements of the program.
