Mission Statement: It is the mission of the Elba Central School District to actualize the phrase “Elba Equals Educational Excellence for Everyone.” We are committed to providing both quality and equity. Every student will have the opportunity to develop to the best of his/her ability.
Elba Standards: In addition to the knowledge and basic skills they need in order to participate in society, graduates of Elba Central School will develop:
1. Empowering skills: decision making, goal setting, creative thinking and problem solving abilities;
2. Communication and social interaction skills;
3. Technological literacy;
4. Total wellness (social, physical, emotional health and self-esteem);
5. The values necessary to participate in society.
As a result of achieving these outcomes, our students will embrace lifelong learning.

Scope: This is an introduction to anatomy and physiology on the 2-stroke and 4-stroke engine. Students will learn the parts of the engine and carburetion system, both through photos and reading, and the manual disassembly and reassembly of each type of engine. The different systems that make the engine work will be explored, such as the ignition system, lubrication system, and carburetion system. A history of the engine will be presented and discussed, as well as other engine designs that are not prevalent in society today.
