Sniffing for a Billionth
Source Institutions
This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

Comparing Sizes of Microorganisms
Source Institutions
In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

Sliding and Stuttering
Source Institutions
Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

Model Wind Tunnel
Source Institutions
In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

Construction and Destruction
Source Institutions
In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

Slide Rules
Source Institutions
Learners make their own simple slide rules out of paper and learn how they work.

Exploring at the Nanoscale
Source Institutions
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

Size Wheel
Source Institutions
In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

Castle Basics
Source Institutions
In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha

Exploring Size: Measure Yourself
Source Institutions
In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

Gravity Fail
Source Institutions
In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

Cutting it Down to Nano
Source Institutions
This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

A Place in Space
Source Institutions
Learners construct and use a "real" 3D coordinate system out of balsa wood and foam core. They will then be able to locate coordinates in space.

The Search for Secret Agents
Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

What am I?
Source Institutions
In this activity, learners examine nanoscale structures of common things.

Exploring Tools: Mitten Challenge
Source Institutions
In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

Be a Scanning Probe Microscope
Source Institutions
In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

Mitten Challenge
Source Institutions
In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

Postcards from Space
Source Institutions
Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the
