In this Bob the Builder(TM)-themed activity, learners go on a nature walk outside and describe what they observe using their senses. Learners discuss everyone's responsibility of taking care of the world. Then, learners use stickers and nature cutouts to create a collage displaying the items they sensed outside, such as wind, sun, flowers, rocks, trees, squirrels, or birds. Learners can also collect small items for the collage while on the nature walk. This activity is featured on page 12 of the "Bob the Builder(TM) — Project: Build It" unit of study.
