Nature-based Early Learning Program  (3–5 years)

Play, explore, discover and learn in this tree-centered early childhood program where children are spontaneous STEM learners with adult staff as their guides.  We take advantage of our institution’s extensive outdoor collections and programming resources to immerse children in a variety of outdoor exploratory experiences in a stimulating, rewarding environment. Our program will allow children the opportunity to play and observe nature throughout the changing seasons while developing literacy skills, social and emotional communication and intelligence, and growing their self-confidence through exploration of their surroundings.  Children will grow strong alongside the trees here at The Morton Arboretum!

The mission of Little Trees is to help young children develop a deep and meaningful relationship with nature through outdoor play and child-directed discovery, creating a foundation for a lifetime of stewardship working towards a greener, healthier, and more beautiful world.

Our curriculum is designed to promote learning by providing an environment that encourages discovery and experimentation while cultivating kindness and empathy, building a growth mindset, and sprouting student scientists.  While exploring several different STEM-focused inquiry units throughout the year, children will have the chance to help shape the content by communicating their interests in each theme.  We investigate each theme by taking nature walks, studying natural phenomena, and engaging in activities that build physical, social-emotional, and cognitive skills.

The Morton Arboretum provides an unparalleled location for nature-based learning.  Children will discover the wonder and beauty found within the arboretum’s 1,700 acres.  Situated on the rolling Valparaiso moraine and bisected by the East Branch of the DuPage River, the Arboretum is home to forests, creeks, savannahs, prairies, and lakes, all of which provide a rich natural environment for exploration and learning.  Experienced instructors trained in nature-based education will share their enthusiasm for the natural world with the children on their daily explorations through the varied environments.  During outdoor exploration, children frequently have the opportunity to observe native wildlife, including white-tailed deer, red-eared sliders, sunfish, bullfrogs, red-tailed hawks, monarch butterflies and hundreds more.  Our quaint classroom, tucked inside the historic Thornhill Education Center, will serve as our home base and provide space for learning stations, dramatic play, art, reading, writing, blocks, and science experiments.
