MOS 3 E McCall Outdoor Science School Sustainable Energy

McCall Outdoor Science School Program MOSS is the only publicly operated K-12 residential outdoor school in the state of Idaho. Offers a unique place in which students participate in hands-on projects and outdoor field activities that appeal to different learning styles. Helps students develop an understanding of the natural and cultural history of Idaho ecosystems.

MOSS Energy Problems Campus power usage is excessive Campus is reliant on non- renewable sources for both heat and electricity It can be difficult to educate students about renewable energy and power generation

Educate students about solar and mechanical power generation Educate students about energy storage Allow students to experience “hands-on” power generation Deliverables

Deliverables: -Mobile Solar Cart -Power Display -Multiple Solar Panel Angles Educational Solar Cart Purpose: Capture Solar Energy Display Power Generation Educate students about solar energy

Solar panel angle adjustment allows students to see power changes during different angles at different times of the day throughout different months of the year. Educational Solar Cart The cart will be constructed using a small solar panel with LED display for monitoring power generation of the panel. This will enable students of all ages to easily distinguish changes in power produced by the panel.

Purpose: Convert Mechanical Work to Electrical Energy Turning shaft of an electrical motor creates an output voltage Hand-Crank Electric Generator
