K-5 Forest Lessons

Science

Experiencing science phenomena is central to science instruction, and a schoolyard forest is a wonderful opportunity for students to directly experience phenomena in the natural world. We have provided a curated collection of lessons and activities that support life sciences education in three main strands: (1) plant structure and function, (2) ecosystem interconnections, and (3) the carbon cycle. This is just the start! Many other connections will emerge for students and teachers as they engage with trees in a spirit of inquiry.

The Carbon Cycle and Climate Literacy

Understanding the carbon cycle is a key part of understanding the science of climate change. Schoolyard trees are an opportunity to directly explore photosynthesis and carbon uptake and storage by plants. Younger and beginning students can start with basic concepts, such as learning about leaves, photosynthesis, and gas exchange. Older and more advanced students can build on this knowledge to tackle these concepts in greater detail and calculate carbon storage by their schoolyard’s trees. This will help students better understand and value how their schoolyard forest is part of the solution for mitigating carbon emissions. 

Trees and Climate Change — Canopy
This activity guides students in calculating carbon storage in a tree based on its diameter and height. It also includes basic background information on photosynthesis and greenhouse gasses. Please note that this activity depends on the tree being at least 2 meters/6 feet high and 0.25m/25 cm in diameter.

Mathematics

Trees and their parts—leaves, twigs, seeds, and flowers—can be used for applying the mathematical skills of sorting, measuring, classifying, counting, estimating, data collection, and understanding patterns. The sensory nature of these materials can make math lessons appealing to a broader segment of the student population and give them an opportunity to collect real-life data to analyze and represent. Below you will find a curated collection of lessons and activities that use schoolyard forests to support math education.

Social Science

Schoolyard forests provide easy and powerful ways to connect students to a place. Mapping activities on school grounds, for example, are a way in which teachers can make connections to the geography curriculum. In addition, teachers can make connections to the schoolyard forest when studying topics such as human modifications to the landscape and resource use, local indigenous knowledge and relationships with trees, the current and historic economic value of different tree species, and trees in ancient civilization mythology. We have provided some curated lessons below that focus on students learning outdoors.

Schoolyard Forest System℠

The Schoolyard Forest System℠ Resource Library is a set of practical tools for schools and districts working to increase tree canopy on public school grounds to shade and protect PreK-12 students from extreme heat and rising temperatures due to climate change. Funding for the first phase of this initiative was provided by a grant administered by the California Department of Forestry and Fire Protection (CAL FIRE) Urban and Community Forestry Program, and private philanthropy.
