Chat Day!

Included in General Admission | What does science tell us about substance abuse and addiction?  Find out by talking with experts in the field!  As part of National Drug and Alcohol Facts Week, OMSI is partnering with several local and national organizations to answer questions and clear up misinformation.


Partners: The Methamphetamine Abuse Research Center, The National Drug Abuse Treatment Clinical Trials Network, CODA, The Northwest Addiction Technology Transfer Center, and The Portland Alcohol Research Center.

Cheese Making

Explore the wonderful world of cheese making! We’ll learn the art and science of making cow’s milk fresh mozzarella cheese in this class. Participants will sample a variety of cheeses, make their own mozzarella, and learn several recipes using their homemade cheese. Recommended for ages 8 and up.


One batch of cheese per ticket. One ticket per batch of cheese, maximum three participants per ticket. 

Cow Eye Dissection

Participants are led through the anatomy of the cow eye while finding out how this sensory organ allows us to see. This class is a follow-up to Squid Dissection. It is recommended that participants take the Squid Dissection Lab prior to Cow Eye Dissection.


One cow eye per ticket, maximum two people per ticket.

Game Masters in Training

Do you have what it takes to be a Game Master? Test your skills in this class that explores the creative and strategic planning required for video game story and character development. Participants will storyboard their own game segments and imagine new characters for classic games. Ages 8+, families and/or groups strongly encouraged.


This is a limited edition class designed to accompany our featured exhibit, Game Masters.

LED Wearable Workshop

Circuits and crafting combine in this hands-on workshop. Learn about sewable soft circuits, and use assorted textiles, conductive thread, electronic components, and your own artistry to make a light up LED cuff to take home. Participants should know how to sew a running stitch, but no electronics experience is necessary.

My 5 Senses

What are the basic scientific tools we carry with us every day?  How do they help us understand the world around us? This lab is designed to explore an assortment of materials designed to stimulate all five senses! We will also explore several senses beyond the basic five.  Students make and take home Flubber.


PLEASE NOTE | An edible fingerpainting activity in this class involves milk, sugar, gluten, and food colorings.  If a student has food allergies or sensitivities, please email scienceplayground@omsi.edu to indicate any specific restrictions at least one week before the class day so we can substitute appropriate non-allergenic materials.

Simple Machines

How does a seesaw work? What makes wheels on a bike go around? How can you lift heavy objects? Playing with gears, wheels, levers, and inclined planes, students learn the ways simple machinery makes our lives easier.  Students take home spoon catapults.


Ages 4 – 7

Bugs & Butterflies

Who are the scientists that study insects, and how do they do it? What are some of the unique features of insects? In this basic introduction to insects, their bodies, and scientific investigation, students will meet live insects and explore the answers to these questions.  Students will create and build an original insect to take home with them.  


For ages 3-6

Be A Naturalist

What does a naturalist do? What does an owl eat? Children discover answers to these questions and more as they practice science skills including observing, taking measurements, and investigating specimens.  An owl pellet dissection is included and students take home their owl pellet artifacts.


Ages 4 – 7
