Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

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).

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

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.

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

“Exploring the Solar System: Big Sun, Small Moon” is a hands-on activity that explores the concept of apparent size and allows visitors to experience this phenomena using familiar objects—a tennis bal

In this activity, learners examine nanoscale structures of common things.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

"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.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

Build and test a scale model of a rainforest canopy walkway.

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).

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.
