Image inspiration! Create a scavenger hunt for a hike during which you collect a variety of pine cones which you later use to create a piece of art for the home or classroom using string and a fallen branch (which can also be collected on our hike). Talk about nature as art and/or diversity in nature.
Create this cool natural mobile-- locating items in under or around a log. (See Life under a Log lesson and resources.) Then, use a calendar to predict how it will decompose. Record observations every two or three days.
