2024-2025 Changes!

Yes! You requested “more” so we will change the program back to semesters and add more homeschool-focused classes. Labs will remain 90 minutes. The Middle School (7-9th) students will stay 2 hours long. We will keep the science fairs, planetariums, films, and assemblies. Things are still being tweaked so keep an eye on the newsletters. We might even bring back our favorite Amtrak to the Seattle-Pacific Science Center trip.
