A nationwide festival celebrating nanoscale engineering and technology.

1. The Nano Research Facility at Washington University
and the Saint Louis Science Center present NanoDays™ 2010
A nationwide festival of
educational programs and
hands-on demonstrations
about nanoscale science
and engineering and its
potential impact on the
future.

2. The Saint Louis Science Center hosts NanoDays™ and promotes the
event to local and underserved school districts.
Over twenty St. Louis schools participated on Friday, April 23 with assistance from the St. Louis Science
Center’s Emerging Technologies Director, Christine Roman. Picture by Vikram Singh.

3. Hands-on demos were provided to the Nano Research Facility via a grant
and kits provided by the Nanoscale Informal Science Network (NISE).

4. The NISE kits promoted the NRF’s goal of providing and developing
hands-on Process-Oriented Guided Learning activities for K-12.

5. The NanoDays™ festival also offers networking opportunities for the
NRF and local school teachers.

demonstration with NRF Administrative Coordinator Dee Stewart. Picture by Vikram Singh.

6. NRF staff member Kate Nelson leads the Measuring Molecules
demonstration.
Measuring Molecules uses balloons filled with a scent extract to introduce the concept of diffusion, molecules
and size.

8. The Magic Sand™ demonstration led by McKelvey scholar Becky
Strubberg, was popular with kids and adults.

9. Nano –Tex™ provided samples of their hydrophobic fabric for the
Nanotextiles demonstration, which students could test with water.

10. NRF User Maureen McKiernan demonstrates ferrofluids (left) with
Administrative Coordinator Dee Stewart (right).
The Ferrofluid demonstration teaches the concepts of nanoscale properties, colloids, and superparamagnetics.

11. NRF User Maureen McKiernan and the Gravity demonstration.
The Gravity demonstration uses different-sized cups of water to show how force interaction can vary with size. The
size of the cup- and amount of water it holds- determines which force is more important, gravity or surface tension.

12. NRF Staff Member Kate Nelson with the Scanning Probe Microscope
demonstration
The SPM demonstration uses magnets to model a scanning probe microscope, allowing the user to “feel” a
magnetic field.

13. Students participate in the NISE StretchAbility demonstration.

14. A participant folds a “bucky ball” model provided by the St. Louis
Science Center with help from the NRF.
