Search: Cart demonstration, Spanish

This is a cart demo about how nanoparticles behave differently, in part because they have a high surface area:volume ratio. Visitors learn that smaller particles have a much higher proportion of their atoms on the surface. Visitors unfold paper cubes, drop alka-seltzer in water, turn potatoes black with iodine, and see fireballs to understand how surface area changes as you get small.

This is a card game which can be played with museum visitors. Visitors will learn the relative sizes of various objects. They compete against each other (or you) to organize their hand of cards into lists of objects from largest to smallest.

This cart demonstration reviews the basics about nanotechnology. Visitors learn that nanoscale objects are very small and have surprising properties because of their size. They also learn about some of the possible technologies that may lead to. They mix chemicals, turn potatoes black, generate electricity, and see invisible light in their exploration.

"Nanotechnology: Small Science, Big Impact!" provides an overview of nanoscale science, engineering, and technology, and includes a variety of hands-on activities and demonstrations.
