While you are out looking for signs of Spring in your yard/ neighborhood see if you can identify any trees by the shape and color of their buds!
Take it a step further by becoming a citizen scientist and logging your data at budburst. org! This data contributes to Phenology, the study of cyclic and seasonal natural phenomena, especially in relation to climate and plant and animal life. If you want to do some art too try printing out a phenology wheel template and drawing pictures to represent the seasons. Check out some examples of phenology wheels here!
