Looking for a fun outdoor project? Take a cue from Swam Rust and calculate a tree’s age.

What does this project explore? You can learn about a tree’s growth and history by observing its rings. Scientists have been able to use the information from the sizes and spacing of tree rings to identify climate change. These studies can also identify trees that are suffering from the early stages of pollution effects or can identify an area that is not getting enough irrigation. Past climate conditions can be discovered and future climate patterns can be predicted from the study of tree rings.
