Homeschool Science Classes at OMSI

Welcome to the Oregon Homeschool Science Club!

Homeschooling in the Chemistry Lab, not our kitchen.
Homeschooling in the Chemistry Lab, not our kitchen.

Our club has been in existence for twelve years.  We meet 24 weeks of the year at OMSI, taking the most incredible classes with amazing OMSI Science Educators, hold science assemblies, head out to OMSI’s Coastal Outdoor School, or take trips to reciprocal science museums, like Seattle’s Pacific Science Center or the Smithsonian’s in Washington D.C..


To join:

  1.  Read through our Science Classes/Activities on upper bar.

Oregon Homeschool Science families come together from all over the Portland Metro area, from Ridgefield, The Dalles, Salem, Oregon City, Seaside, and Hillsboro.  There is no single style of homeschooling that guides our families, only that quality instruction and high academic experiences are common goals.


Discovery Scientists at OMSI
Our youngest scientists in the Discovery Lab are using the concepts of mixtures in a basic chemistry experiment involving lots of paint.

We have families with students that have learning differences/difficulties, families with TAG students, homeschoolers blending schooling approaches (traditional and homeschooling siblings), and families in hybrid-homeschooling charter schools.

We are eclectic!

We are homeschoolers.


Intermediate homeschooling scientists have the opportunity each year for dissections. (We also provide alternative dissection opportunities to those that request.)


Classes are 60 minutes long, meeting Tuesdays from mid September to the end of April, with a long Winter holiday break and a two week Spring vacation.  Students often take two classes and the program is set up with a 15 minute passing time.

Events are scheduled throughout the year.  Watch the calendar.


The Fabulous Fossils class is an annual hit with our Discovery and Beginning homeschool scientists.

Our program remains a coop as we strive to keep the costs down for everyone.  Each classroom has a dedicated parent volunteer for the entire year as well as a rotating second parent helper.  Each family is asked to sign-up once per child.   Per our partnership with OMSI, this is not a “drop-off” program.  Families are required to stay on the OMSI campus.  After delivering your child to their class, you are free to enjoy a cup of coffee, find a quiet corner to read or write your grocery list, or enjoy a conversation with other homeschooling parents.

Events are family activities.  Parents and students travel together, explore together, and go home to continue the learning.


  • OMSI Membership $75 per family
  • OHSC Registration $25 per student
  • Lab tuition $100 per 12 week term/one hour class
  • or $200 per 12 week term/2 hour class
  • Events are individually priced per student and adult.  See announcements.
Starting in the Advanced Science courses (5th/6th/7th grades), students start learning to take notes, develop research journals, and begin writing different parts of a lab report. By Middle School Challenge, they are conducting their own research project.


Classes and trips do fill up early. New events are added throughout the year, watch the email announcements.  Please contact the coordinator to check on availability.  Some changes do happen right before the school year, as families do change their plans about homeschooling and end up dropping their spot.
