  • Middle school geologists analyzing different soil samples in groups and collaborating to develop a list of characteristics for classifying them.

  • High school political scientists working together to write a constitution and answer questions related to criminal and civil cases.
  • High school physicists working on a group project involving force, energy, gravitation, and velocity.

Students make impact in community during Service Week

February 24th, 2017|

Middle schoolers serve others

Middle School Happenings:

Last week was Service Week. Students were assigned to one of several service groups as we put some practical application to the things we have been learning in Bible class. One great way of loving others is to provide some sort of service to them. Our students were able to experience a variety of opportunities to do just that. Service week is always a wonderful opportunity to step out of the classroom and to see the world from a different perspective. We certainly had a memorable, perhaps even life-changing, experience! Check out the OCSI Facebook page or search OCSI Service Week on Youtube for more videos and pictures of Service Week.

Each month the middle school teachers are focusing on a particular character trait among our students. To go along with Service Week, this month’s character trait is service. In addition to the service we are doing for Service Week, we are looking for spontaneous acts of service in middle school. Hopefully, we see many examples—not only this month, but even beyond!

Students use their learning to serve

OCSI Connections:

At OCSI, we want our students to use their learning to serve God and others. And that’s what our students are doing. Students are helping each other in the classroom and on the playground. And last week, students in grades 6-12 were involved in Service Week. They sang at a retirement home, developed web pages for churches, cleaned up beaches, collected clothing donations, and more!

Thanks to all parents and community members who helped with Service Week, including those who provided clothing donations!

P.S. Road construction continues along the far end of the playing field. Through our PlaySafely Campaign, we are raising funds so we can install poles and netting between the playing field and new road. We invite you to give a gift to the PlaySafely Campaign in Japan or the US.
