For a creative writing activity, have the students write the biography of the tree. Concrete poems are poems that are shaped like the object they describe. Find pictures of patterned objects such as seashells, leaves, trees and flowers, or bring in examples of these items that students can touch and feel. Talk about the different kinds of patterns students observe. After making lists of adjectives that could describe each item, have students create a poem in that object's shape.
Snowflakes contain some of the most delicate, intricate patterns in nature.
Those patterns can be preserved by making snowflake slides. During a snowstorm, spray the slides with clear acrylic paint. Hold each slide until it catches a few snowflakes and place it in a sheltered place outside until the paint has dried. This can take 4-12 hours depending on the temperature. Note that materials must be kept outside or in the freezer until you are ready to use them.
