Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

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).

Coffee to Carbon
Source Institutions
In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

Paper Cutting
Source Institutions
In this activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.

Exploring Materials: Ferrofluid
Source Institutions
In this activity, learners discover that a material can act differently when it's nanometer-sized.

Invisible Sunblock
Source Institutions
In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

Invisible Sunblock
Source Institutions
This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.

Exploring Forces: Gravity
Source Institutions
In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

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.

Soap-Film Interference Model: Get on our wavelength!
Source Institutions
By making models of light waves with paper, learners can understand why different colors appear in bubbles.

Volume, Mass, and Density Boxes
Source Institutions
This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

Ready, Set, Fizz!
Source Institutions
In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

Space Jell-O
Source Institutions
Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

Exploring Properties: Surface Area
Source Institutions
This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA
Source Institutions
Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

Magic Sand: Nanosurfaces
Source Institutions
This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).
