Add to listGo to activity
In this activity, learners use pinecones to create a hygrometer, a device that measures the moisture content of the air. Learners discover that in dry air, pinecones open their scales to disperse seeds. In dampness and rain, they close them to protect the seeds. Use this activity to discuss how both plants and animals are affected by their environments.
