Celebrate the first day of spring with STEM in Bloom, an all-day program where young scientists and engineers explore the science of the changing seasons, plant growth, balance in nature, and the engineering marvels inspired by springtime. Students will engage in hands-on, project-based lessons that combine environmental science, engineering design, and creative technology. Through these activities, learners will investigate how sunlight, temperature, and ecosystems change during spring, build models that mimic natural systems, and design innovative ways to protect and celebrate our planet. Classes are nonrefundable, but rescheduling is available for missed classes.

Flowers aren't just pretty, they play an important role in our ecosystems and in providing food and medicine for humans. In this badge workshop, Junior Scouts discover the science behind flowers. Using our GROW and Life Science Lab Galleries, explore medicinal plants and create a bouquet to take home. All requirements of this badge will be met.

Educational Program focusing on forest canopy ecosystems and animals. Part of the 2025-2026 Homeschool Days series exploring Environments Around The World.

Part of the 'Life in Balance. Exploring the Diverse Ecosystems of the World' series. Through expert talks and hands-on activities, this program explores temperate ecosystems, showcasing the diversity of life and the unique ways organisms adapt to their habitats.

Engross yourself in science as you investigate icky, sticky, slimy, and smelly experiments! Get an up close look at worms, bugs, slugs, and other gross parts of our Arboretum ecosystems. Multiple sections: June 15-19, July 13-17, August 3-7. All camps currently sold out with waitlist available.

Campers will be immersed in a captivating exploration of Earth science and ecology. Throughout the week, campers delve into the intricate systems of our planet, studying ecosystems, biodiversity, and natural resources. This week was formerly 'EcoDetectives'; Some elements of EcoDetectives will still be part of this week. Camp runs 9:00 AM - 3:00 PM daily.

Discover and explore the natural world that exists within five local ecosystems that make up Maine's ecology. Campers will learn the basic ideas of ecology and how living things interact with each other and their nonliving environment. Each day will have a different theme focusing on the habitats around us including forests; freshwater, coastal, and peatland wetlands; and open field habitats. Through daily field trips and activities, campers will observe and study the natural environment of plants and animals typically found within habitats located in our community. Campers will gain an understanding of how plants and animals use physical and behavioral adaptations, as well as interactions with other species, to live in these habitats. Through self-guided and group projects, campers will build a strong foundation for an understanding of ecosystem ecology. Open to ages 9 to 12, no experience needed. Camps run Monday through Friday, 9:00 am until 3:30 pm.

Dive into the world of dinosaurs through the lens of engineering and science in this immersive LEGO®-powered STEM course. Campers will apply critical thinking and problem-solving skills to design and build secure habitats for herbivorous dinosaurs and go on expeditions to discover elusive species. This course challenges campers to collaborate, innovate, and deepen their understanding of biology, engineering, and prehistoric ecosystems, all while bringing the Jurassic world to life, brick by brick. 5 sessions of 3 hours each. Registration opens January 28, 2026 at 12:00 PM. 17 openings remaining.

Campers will explore the captivating realms of biology and health sciences! This week, young scientists will delve into the wonders of the human body, the intricacies of ecosystems, and the marvels of cellular life. Through hands-on experiments and engaging activities, they'll uncover the secrets of living organisms and learn how to keep our bodies healthy. This week was formerly 'BioBuzz' and has been re-imagined for summer 2025 to include brand new bio and health sciences content! Camp runs 9:00 AM - 3:00 PM daily.
