Demonstrations and Activities for ALL Ages

Play (and learn) at the Robotics and STEM Showcase at CenterPlace Regional Event Center. This FREE event, brought to you by Horizon Credit Union, Exploring Families and Events On Fire, will entice all ages to engage in STEM (science, technology, engineering, and math) and robotic activities! This year’s theme is chemistry because we are celebrating the 150th birthday of the Periodic Table of the Elements!

150th birthday of the Periodic Table of the Elements

IYPT logoThe Periodic Table of Chemical Elements is one of the most significant achievements in science, capturing the essence not only of chemistry, but also of physics, medicine, earth sciences and biology. 1869 is considered as the year of discovery of the Periodic System, and Dmitri Mendeleev was a major discoverer. 2019 is the 150th anniversary of the Periodic Table of Chemical Elements and has therefore been proclaimed the “International Year of the Periodic Table of Chemical Elements (IYPT2019)” by the United Nations General Assembly and UNESCO.


  • Learn all about the Eastern Washington Regional Science and Engineering Fair held in Spokane in the spring.  It’s for all students in grades 6-12 to learn about companies in Pullman, UW Medical School, WSU Health Sciences campus, Spokane School District and about 40 local teachers. It is a research project competition for students in STEM as well as a STEM festival.
  • Joshua Johnson of Objects Unlimited, makes aircraft parts, primarily drone wings and frames. His company also makes their own manufacturing machines. Joshua and his father both worked for or with NASA so he has lots of artifacts to see and touch, including a piece of brick made for the space shuttle, A Prandtl-M wing meant to demonstrate unmanned flight on Mars, printed circuit boards from the computer that calibrated the replacement o-rings on shuttles that flew post Challenger, seats from several historic but unfortunately fatally crashed aircraft and a wing he designed using data from the NASA Prandtl program.

  • Imagine, design, create, and build with a floor full of LEGOs.

  • Watch 3D Printers in action! RoboSprout is devoted to opensource/openhardware. Their focus is on 3d printers, rapid prototyping, and small batch contract manufacturing. You won’t believe what they can print! 

New this year! STEM Shows!

Chemical Reactions
Radical Rick of Extreme Science
12:00 and 2:00 pm

If you look up the definition of a chemical reaction, you may get so bored that you don’t even finish reading the definition! Radical Rick will bring chemical reactions to life in this fun filled and (literally) EXPLOSIVE show! When they say that there are three indicators of a chemical reaction but Radical Rick tells us that the fourth, and most important indicator, is the fun and exciting reaction he gets from the crowd when he demonstrates liquids that change colors by shaking them, producing golden pennies just by adding heat and exploding a hydrogen bubble in an audience members hand!

Fun With Air
Radical Rick of Extreme Science
1:00 and 4:00 pm

This is one of Radical Ricks favorite shows! Come explore the fun you can have using the air that is around us every day. Some say that we need air to survive but Radical Rick will show us how to use the air around us to learn about pressure, Bernoulli’s principal, the states of matter in a fun and exciting way! Radical Rick will also show you how to make your own voice activated laser generator and show you how you can get your lasers to dance to the music!

Chemistry and the Periodic Table
Patrick Nurre of Northwest Treasures
12:00 and 2:00 pm

We will have some fun with a few elements and observe some active properties of elements that you consume in your foods each day. The Periodic Table was a wonderful invention given to us in 1869. Chemistry makes so much more sense when you can understand the Periodic Table and the interplay of elements and why they behave the way they do. Knowing this Table is the key to enjoying and understanding chemistry. This presentation will focus on helping you figure out how and why the elements are arranged the way they are. Chemistry is fun!

Geology and the Periodic Table
Patrick Nurre of Northwest Treasures
1:00 and 4:00 pm

Part of the mystery in understanding rocks and minerals is understanding what role the elements play in the make-up of the rocks. Atoms make up elements. Elements make up minerals. And minerals make up the rocks. Once you grasp this simple concept, you will gain a new interest in the rocks all around us that we take so much for granted. In this presentation we will explore the answer to questions like what gives rocks their color and why do they have various properties? We will discover why certain rocks contain fossils and others do not and how we can easily identify and organize the rocks – all with the help of the Periodic Table.

NASA Ambassador presentation
Joe Bruce
12:00, 1:00, 3:00, 4:00 pm

Meet NASA Ambassador Joe Bruce! Touch his amazing artifacts, like his space glove, piece of Mars, space vehicle tire, and space shuttle tile. He wants to answer your questions! The NASA Solar System Ambassadors (SSA) program works with motivated volunteers across the nation to share the latest science and discoveries of NASA’s missions through a variety of events that inspire their communities. Joe received a BA in Secondary Science Education from Central Washington University in 1981. Joe has been a member of the Planetary Society and Rotary Club 21, Spokane. He is an educator, lecturer, and artist who offers programs in Washington and Idaho.
