2023 Wyoming State Science Fair Activities 

This page contains information about two extracurricular activities in conjunction with the Wyoming State Science Fair.  

The first is the popular Pizza and Planetarium, returning on Sunday, March 5th. For those who have participated in this event before, please note that we have changed the ticketing system to a pre-registration process.  See below for more details.

The second is Teacher STEM Experiences. In the past, we have provided hands-on STEM activities for students, however since students will not need to be away from their projects for pre-judging this year (as all material will be available virtually to the judges prior to the science fair) we have decided to open this opportunity up to teachers!  These activities will take place on Monday, March 6th from 10:15 – 11:15am. We are asking teachers to pre-register for the activities, see below for more details!

 Pizza and Planetarium

Pizza and planetarium is BACK! Join the Wyoming NASA Space Grant and the Physics and Astronomy Department on the evening of Sunday, March 5th for pizza, physics demos, and a planetarium show.

This year, we will be PRE-REGISTERING attendees online. (Please note this is a change from the ticketing system at registration in previous years.)

In order to pre-register your students, visit  

Note that we do have enough space for all attendees, but time preferences will be given on a first-come, first-serve basis.

Pre-Registration will open at 7am on Wednesday, Feb. 22nd

 Pizza & Demos

You may sign up for pizza & demos at 5:30, 6:30, or 7:30.


You may sign up for the Planetarium at 6:30, 7:30, or 8:30

You may sign up for both the Pizza and Demos session AND the Planetarium show, but be sure to not sign up for them at the same time!

 Teacher STEM Experiences

For teachers, parents, and chaperones of students at the Wyoming State Science Fair

While your students wow the judges, take an hour (10:15-11:15am) on Monday, March 6th to participate in one of our STEM experiences!

 Activity Options:

“Seeing” Science: Exploring Technology Used to Answer Questions in STEM

Come explore the new state-of-the-art Science Initiative Building on the UW campus and experience two of the instruments we use to answer various STEM research questions, the Micro-CT Scanner and the X-Ray Diffractometer. You may be familiar with a micro-CT if you or someone else you know has ever had a CAT scan at the hospital. A micro-CT is just a ‘micro’ version of a CAT scanner! It collects information about millimeter-sized objects by taking many X-ray images from different rotation angles. This allows us to generate a 3D rendering of the object, which can then be further analyzed and studied. This technology is useful to many different STEM fields, including biology, materials science, geology, archaeology, paleontology, and engineering. It allows us to see an object’s composition at the micrometer scale without cutting open or damaging a sample. You will be able to meet the researchers working with this technology who will demonstrate how we can use micro-CT scanning to help us understand the biology of the brain and the study of human diseases such as Alzheimer’s and other related dementias. The X-Ray Diffractometer can provide detailed information about the internal lattice structure of crystalline molecular solids, including unit cell dimensions, bond-lengths, bond-angles, and details of site-ordering. Overall, it can help determine the 3D structure of molecules by examining how X-rays interact with the crystals of those compounds. This technique is used widely in chemistry, molecular biology, pharmacy, physics, and chemical engineering. Teachers in this workshop will get to experience the Micro-CT scanner from 10:15-10:45am and then head up to the X-Ray Diffractometer from 10:45-11:15am. Come explore STEM with us!

Scanning Electron Microscopy (SEM) of Materials for Science Research

Introduction to the scanning electron microscopes we have on the UW campus, what kind of research can be done, and what samples/signals “look” like on the SEM

Explore the UW Geological Museum and Learn how to Prep a Fossil Fish!

Wyoming has one of the best fossil records in the world. Join our session for a tour of them museum followed by a session on how to prep a fossil fish piece, and take this knowledge back to your classroom!

Origami Circuits with the Innovation Workshop

Combine the ancient art of origami with modern technology in this fun and quick activity. Create interactive, glowing, paper designs using LEDs, origami art pieces, and some simple circuits.

All workshops require pre-registration!  Sign up TODAY as many have limited capacity!
