STEAM EXPO presented by:



The SCOPE STEAM Expo is a fun, engaging, educational area featuring free hands on activities in science, technology, engineering, arts and math. Check out the video capturing all the fun SCOPE had at last year’s Fair Saint Louis.

The SCOPE STEAM Expo will be located in the teardrop on the south side of the Arch.


2018 SCOPE STEAM Expo Exhibitors!

National Geospatial-Intelligence Agency (NGA) – come visit the NGA and do hands-on activities focusing on science associate with geospatial analysis.

National Society of Black Engineers – build Lego robots and see how electric current flows

SCOPE – come by to make 3D glasses. Use your inner creative innovator for 3D plant science, space, and find ways to keep all the STEAM fun and inspiration going after Fair St Louis! Design your own 3D art at home, along with other activities for all ages…on SCOPE’s free resource website. Stop by, interact  and experience Science, Technology, Engineering, Art, and Math-STEAM, then…EXPLORE pathways, opportunitues and partners SCOPE brings to teachers, homeschoolers, students, families and community. @ExploreFutures

St. Louis Community College Plant & Life Sciences – decoding can be fun – see how you can decode your name, nursery rhymes build a monster decoing the pattern of color dots.

DNA Bracelets
A codon is a sequence of three nucleotides (a combination of A, T, C, or G) that together form a unity of genetic code in a DNA. Each codon gives us the secret code to make an amino acid. Students will explore the basis of DNA sequences and complementary base pairing: A pairs with T, C pairs with G. For this activity, students will break the genetic code of their first name with color coded beads for base pairs.

Bioinformatics Activity
The DNA language consists of billion letters of A’s, T’s, C’s, G’s and it is hard for us to decode the hidden message. In this activity, students will align puzzle pieces of short reads of nursery rhymes to model the understanding of how gene expression are determined.

Monster DNA
Students will use an online computer program to build a monster by decoding the pattern of color dots using a table to show the combinations we can make with different colors and string lengths. Students will decode the monster genome and add parts to their monster through a computer game/simulation.  This illustrates how even a small number of gene combinations can combine to present 100s of phenotypic results.

Saint Louis Science Center – Explore space and the moon with the Saint Louis Science Center. We will have a 3D printed moon and Saturn V rocket, Saturn V blueprints and hands-on activities about caters and volcanoes. Check out how we could be able to grow food in space with the “Mars Farm!” Then, come to the Science Center to see Destination Moon: The Apollo 11 Mission, featuring the Command Module Columbia and 20 artifacts from the historical mission that landed humans on the moon. See more here. For information about the Saint Louis Science Center, please visit

United States Air Force – Check out this fully immersive VR experience where users realistically assume the role of a Special Operations Airman facing daily challenges. From feeling the exhilaration of a H.A.L.O. (High Altitude Low Opening) free fall to entering “Jump School,” learning to use vital equipment and master required skills such as parachute control and night landing. Air Force Special Ops Nightfall is both tangible and educational part of inspiring the community.

University of Missouri – Kansas City – look how fun science can be:

  • A bicycle on a stand with a generator (kids pedal and light an incandescent lamp)
  • A demo of non-Newtonian fluid (cornstarch and water on a speaker)
  • Wireless electricity demo (low powered, people can light a fluorescent tube held in their hand)
  • Electromagnetic tug of war (visitors can try separating an electromagnet that is powered only by a single “D” cell)
  • Whimshurst machine (static electricity generator)
  • Jacob’s ladder (scary movie prop fully encased in plastic so no worry of people getting shocked)
  • A magnetic levitation display (small cube magnet that floats magically in the air)
  • A cathode ray tube that visitors can deflect an electron beam with a magnet and see the result on a phosphor screen (how the old school television worked)
  • A plasma popper (this uses a small amount of propane or MAPP gas to create the illusion of a sci-fi plasma gun)
  • Some kinetic art to attract visitors.
  • A Bernoulli demo (beach ball with a high velocity air blower, the ball stays in the airstream)
  • An infinity mirror (optical illusion)

USS ST LOUIS (LCS-19) Sea Perch – Play with Underwater Robots!   Maneuver the underwater Robotics “Sea Perch” submersible.   Learn about the Navy ship, USS St. Louis being constructed right now and the USS St. Louis STEAM Initiative.   Watch a video of how students all over St. Louis are participating in this program: building Sea Perch kits and competing in the annual St. Louis competition each year.  Talk with kids and mentors who are part of this program from Pattonville, Parkway and Jennings School Districts.
