St. Anthony Tri-Parish Catholic School

St. Anthony Tri-Parish Catholic School St. Anthony Tri-Parish Catholic School was established in 1927 to provide students with a Christ-centered education. Today, St.

Anthony's Catholic School was dedicated on September 27, 1927, in the belief that education is one of the most important ways that the Catholic Church fulfills its commitment to bring about the kingdom of God. Anthony's Tri-Parish Catholic School educates over 200 students, from preschool through eighth grade, meeting and/or exceeding all Wyoming state academic standards while offering students a Gospel-based perspective. All SAS teachers have degrees and are highly qualified in their fields. Multiple teachers have their master's degree. Three students from the 2021 graduating high school class at Natrona County High School earned Valedictorian status and the Salutatorian from Kelly Walsh High School was also a SAS Archangel. 🥰

We are proud of our 90+ years of academic excellence while striving to learn and teach in a Christ like environment. Students of all religious faiths are welcome and financial aid opportunities are available.

The preschoolers had an exciting Bike Day this week! They brought their bikes from home and enjoyed multiple trips outside throughout the day to ride with their friends.

Bike Day gave students the opportunity to practice balance, coordination, and safety skills while having plenty of fun in the fresh air. There were lots of smiles, laughter, and happy riders as they zoomed around and enjoyed this special activity together! It was a wheel-y great time!

The second graders are studying summer and wanted to find out the best material to wrap a popsicle in to keep it from melting. They tested a paper towel, a paper bag, aluminum foil, and a plastic bag.

The students discovered that aluminum foil worked best because it reflects sunlight and does not absorb as much heat as the other materials. Next time you're taking popsicles on the go, try wrapping them in aluminum foil to help keep them cold!
