Discover / Explore / Investigate

The science department at Lincoln Academy offers a wide selection of courses in both physical and life sciences. There are introductory, honors, and AP level courses in a variety of subjects. The science faculty are creative and dedicated teachers. They have a diversity of teaching experience and background in scientific research and careers. The courses include frequent hands-on experience in our fully equipped lab classrooms. Science field trips, both local and international, are part of our science courses. The science program also offers students the opportunity to apply their learning through clubs and activities like the Climate Action Club, Marine Explorers, and Science Olympiad. We also regularly connect students with field research experiences which abound in the area.


A core value at Lincoln Academy, exploration is the goal of every science class


the LA science curriculum encourages all students to discover new ideas in real time

Celeste Mosher

Celeste Mosher grew up in western Maine where trips to the coast were the highlight of summer. Two educational voyages aboard the Schooner Harvey Gamage as a teen affirmed her interest and love of all things marine. Celeste received a Bachelor of Science degree from the University of the Virgin Islands where she began her marine conservation efforts working on coral reefs in the Caribbean. She returned to Maine to pursue graduate work at the Darling Marine Center and received her Masters in Oceanography from the University of Maine in 2008. Her professional experience includes oceanographic and marine biological research, science education, and community outreach. Besides being on the water, she enjoys hiking and finding great books to read. She currently resides with her family in Newcastle, working and playing in the unique beauty of coastal Maine.

Prema Long : Science Faculty
Prema Long

Growing up in Fort Kent, Maine with four brothers meant that Prema spent a lot of time outdoors collecting, befriending, and taming any living thing that she could find. She attended the University of Maine at Farmington where Ecology became her passion. After a short stint working in the Forest Service's Entomology Lab, Prema moved to Wiscasset to work at The Chewonki Foundation where she spent five years teaching, guiding wilderness trips, and doing environmental monitoring. Prema decided to transition into teaching full time and attended the University of Southern Maine's ETEP program to earn her Master's degree in Education. Prior to working at Lincoln Academy, Prema taught Science at Wiscasset High School. She lives in Topsham with her partner Matt, two moderately well-behaved dogs, and a flock of unruly chickens. In her free time she enjoys reading, canoeing, fishing, cooking, and spending as much time outside as possible.

Seth Platukis : Science Teacher
Seth Platukis

Growing up in the northeastern region of Pennsylvania, Seth Platukis found many opportunities to be immersed in the natural wilderness by searching for fossils, minerals, life-forms, and stars in his backyard. He found himself heavily drawn to the beauty of life and preserving the natural world, while sharing this information with others. He decided to dig into his consistent calling of being a teacher after graduating from the Hazleton Area Academy of Sciences and attending Wilkes University. From there, Seth moved to the midcoast region, where he still resides, living in Bath. For the first two years of his career, he taught a variety of 6-12 STEM and CTE courses at Wiscasset Middle High School. In addition, Seth loves to spend his free time swimming, taking photos, cooking, and hiking the great Maine outdoors.
