Exploring Materials: Nano Gold
Source Institutions
In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.
Exploring Products: Nano Sand
Source Institutions
In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.
Exploring Tools: Special Microscopes
Source Institutions
In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.
Exploring Materials: Thin Films
Source Institutions
In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.
Exploring Materials: Hydrogel
Source Institutions
In this activity, learners discover how a super-absorbing material can be used to move a straw.
Exploring Products: Nano Fabrics
Source Institutions
In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.
Exploring Size: Ball Sorter
Source Institutions
In this activity, learners use sieves with different-sized holes to sort balls by size.
Exploring Materials: Graphene
Source Institutions
In this activity, learners investigate the properties of graphene and graphite.
Exploring Forces: Static Electricity
Source Institutions
In this activity, learners investigate what happens when you build up static electricity on plastic balls.
Exploring Structures: DNA
Source Institutions
In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.
