Warrior Leadership In Action

Ontario Spring Clean Up

Today, several of our Warrior Leadership students traded books for trash bags and hit the streets of Ontario to give back to the community!

From trash to triumph, these Warriors proved that leadership isn't just taught—it's lived.

From Class to Cocina

Spanish 4/5

What happens when you take a group of upper-level Spanish students, throw in a table full of tacos, and challenge them to speak only Spanish? Magic!

The Spanish 4/5 class trip to Pancho’s Tacos wasn’t just about food--it was a living classroom. From ordering in Spanish to navigating salsa preferences and tortilla choices, students got a taste of both language and culture in the most flavorful way possible!

Cabaret 2025

Hosted by the Ontario Music Boosters with outstanding performances by the jazz band and show choir, Rhapsody in Blue

Brains, Bonds, and a Bit of Humble Pie

Academic Challenge Competes At Primrose

The Ontario Academic Challenge team took on the brilliant minds at Primrose Retirement Home in the 3rd Annual Dan "The Trivia Man" Henige Memorial Challenge—and let's just say the residents still run the trivia game! ??
Three rounds, three wins for Team Primrose! ????

Our students had an amazing time connecting with the residents, sharing laughs and a love of learning. We’ll be back next year for a rematch!

Powering the Future, One Experiment at a Time!

Environment & Society CCP

This week, the Environment & Society CCP class turned up the energy—literally!
Students explored alternative energy solutions, breaking down how each source is created, its pros and cons, and what the future might hold.

Then it was time to bring the science to life:

Brewed their own biodiesel from vegetable oil
Built a working wind turbine that generates power
Activated a hydrogen fuel cell—yes, it works!

The future of clean energy might just be in this classroom!

Turn Up The Volume

History of Rock & Roll Class

Students in Mr. Coley's History of Rock and Roll made Hall of Fame displays for genres of 1970s rock -- Glam, Southern, Heartland, Metal, Punk, Progressive, Yacht, FM Hits, or Underground. They had to make displays for the genres and feature an artist of their choosing. Students put together playlists, videos, and artifacts. The artifacts could be pieces of clothing, jewelry, etc. Some brought actual tickets and merch from home. And some students decided to become the artifact himself! Well-played Gene Simmons :)
