I’m excited about science at OCSI

IMG_1623I’m excited that our student scientists are…

  • Posing and testing hypotheses about the effect of the height of a ramp on force and movement (kindergarten).
  • Classifying mammals, birds, fish, reptiles and amphibians and researching the characteristics of each (elementary).
  • Collaborating with partners to create models for teaching classmates about geological formations in the ocean (middle school).
  • Calculating acceleration and velocity of road bikes vs. mountain bikes in their unit on motion (high school).

I’m also excited that OCSI teaches social studies from the perspective of the Bible’s overarching story of creation-fall-redemption-restoration:

  • Creation (What’s God’s purpose?): God created the universe to operate in an orderly system to show His nature and to provide a hospitable home for people. God created people in His image to live in grateful, dependent relationship with Him and to care for His creation as His regents.
  • Fall (What’s wrong?): Because of sin, our relationships with God, creation, and each other are broken. We glorify the creation (including ourselves) over the Creator. We abuse creation (out of arrogance or ignorance) for our own profit. The creation is not hospitable to us.
  • Redemption (What difference does Jesus make?): Jesus submitted Himself to physical laws (He was tired and hungry; He suffered and died) and rose above them (He did miracles and rose from the dead). Because Jesus died and rose again to free us from the power of sin, we are free to live in grateful, dependent relationship with the Creator, to delight in and care for creation as His regents, and to further develop creation’s potential in order to serve God and our neighbors.
  • Restoration (What will you do?): The Science Department equips students to walk with God and impact the world for Him. To do this, we help students to understand how creation operates and to apply scientific inquiry to learn more in order to develop creation’s potential for God’s glory and to help our neighbors.


Mrs. Cashon arrived in Okinawa in late November and began teaching high school biology, chemistry, and marine biology in late January. What does she like about teaching at OCSI? “I love the students,” she says.

Students make impact in community during Service Week

Enjoy the view from OCSI

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 involved in hands-on learning

High School Happenings:

Mr. Lloyd’s Intro to Computer Science students are currently learning how to program microcontrollers to control servo motors and read information from sensors. Advanced Computer Science students have recently made a self-watering hydroponics system growing chili plants with fish and are currently working on an “Internet of Things” motion-activated light with LEDs.

We are excited about the hands on learning that will be taking place in some of the middle and high school science classes during the 3rd and 4th quarter. Different classes will dissect such things as earthworms, fish, crawfish, frogs, and pigs. Pictures to come!

This week high school students and teachers are saying farewell to Mrs. Reihle. Mrs. Reihle has served faithfully at OCSI and will truly be missed. We also are welcoming Mrs. Lesley Cashon to the OCSI family. Mrs. Cashon recently moved to Okinawa and will be covering the Biology, Chemistry, and Marine Biology classes for the remainder of the year.
