Surface Area
Source Institutions
In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.
Exploring Materials: Liquid Crystals
Source Institutions
In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.
Liquid Body Armor
Source Institutions
In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.
Which Powder is It?
Source Institutions
In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.
Checking For Starch
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.
What's In Your Breath?
Source Institutions
In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.
Forms of Carbon
Source Institutions
In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.
DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
Pickle-oh!: Musical Pickle Instrument
Source Institutions
What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.
Enzyme Action
Source Institutions
In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.
Nature of Dye
Source Institutions
"Nature of Dye" allows participants to create their own dyes and art while exploring how chemicals interact and how these interactions can have real-world applications.
Changing Colors
Source Institutions
In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.
Finding Colors
Source Institutions
In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.
Mars from Above: Carving Channels
Source Institutions
In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.
Carrying Charges: Testing for Conductivity
Source Institutions
Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
Bubbles: Using Controls
In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.
Sand, Plants and Pants
Source Institutions
In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.
Biomimicry: Synthetic Gecko Tape Through Nanomolding
Source Institutions
In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
Paper Whites
Source Institutions
Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.
