The "Chemistry Makes Scents" lets participants use their noses to distinguish between chemicals with very similar structures. Some molecule pairs contain all the same elements, arranged the same way but flipped in a "mirror image." While these chemicals can behave...

This online presentation and discussion covered the science behind three of the 2017 Explore Science: Earth & Space toolkit activities - Rising Seas, Investigating Clouds, and Orbiting Objects. After a brief overview of each activity and associated materials, Laura Peticolas,...

"Exploring the Universe: Orbiting Objects" is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well. The activity models gravitational attraction in space. Participants investigate how changing conditions can cause...

This lesson introduces scale by demonstrating scales as factors of ten. This facilitates the introduction and reinforcement of the metric scale and paves the way to the discussion of lengths that are smaller than what can be seen with the...

"Nanotube Models" is a facilitated tabletop program aimed at educating the public about the properties and applications of carbon nanotubes. Visitors will be able to use Molecular Visions model kits to build carbon nanotubes. The models can be started by...

Using LEGO® models to show various physical and chemical principles related to nanoscale science and technology
