Educational Opportunities

National Arbor Day is April 28, 2023. Arbor Day was started in 1872 in Nebraska City, Nebraska. It is estimated that over 1 million trees were planted on that day. People from all over the country have enjoyed planting trees with friends and family to help make our world a little bit better, one tree at a time.

Many people plant trees in dedication of someone special, to help make a neighborhood more beautiful, or to simply have an opportunity to help something grow. Whatever the reason, Arbor Day is a special day to recognize and remember one of our greatest treasures - trees.

Use these resources to help you celebrate trees near you throughout the year.

Developed with preschool educators and early childhood specialists, this guide is designed for educators who work with children ages 3 to 6. It offers over 130 experiences that engage children in outdoor play and exploration. Topics include exploring nature with five senses, meeting neighborhood trees, and experiencing trees through the seasons. An accompanying CD features music from children's musician Billy B. Brennan that encourages children to sing, dance, and move.

Activities adhere to the guidelines set forth in the national standards for early childhood education – NAEYC Criteria for Curriculum, Head Start Child Outcomes Framework and the NAAEE Early Childhood Environmental Education Guidelines for Excellence. Additional correlations have been drafted to Iowa Early Childhood program and curriculum standards – Quality Preschool Program Standards, Iowa Early Learning Standards, and the Iowa Core Curriculum.
