Lower School Environmental Ambassadors are reducing energy consumption here at Ellis by raising the funds to install an automatic light for the bathroom by the computer lab. The light, which uses motion sensors, will reduce energy usage and costs, both of which are important issues to the student leaders involved.  Lower School Environmental Ambassadors are students in grades 2 - 4 who meet weekly over lunch to discuss environmental issues that concern them. They then plan and execute projects to make a difference with those issues. Environmental Ambassadors have demonstrated leadership potential and a personal interest in sustainability.
