DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
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.
Wash Away Germs
Source Institutions
Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.
Battle the Baby!
Source Institutions
In this interactive game, learners compare their music-listening skills with that of a three-month-old baby.
Learning the Land
Source Institutions
In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.
Soil Density
Source Institutions
In this activity, learners will test soil content using their sample, some water and a container that seals.
Biobarcodes: Antibodies and Nanosensors
Source Institutions
In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
The Great Plankton Race
Source Institutions
In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.
Exploring Size: Scented Balloons
Source Institutions
In this activity, learners use their sense of smell to explore the world on the nanoscale.
Strong Bones, Weak Bones
Source Institutions
Most people will break a bone in their body at some point in their life, but how much force does it take to break one?
DNA Extraction from Wheat Germ
Source Institutions
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.
Squash Dissection
Source Institutions
In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.
Crayfish Investigations
Source Institutions
This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.
DNA Extraction from Cheek Cells
Source Institutions
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.
Design a Grabbing Tool
Source Institutions
Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
Magnification vs. Resolution: Can you see the flag on the Moon?
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.
Clam Hooping
Source Institutions
In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.
See the Light
Source Institutions
Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.
