Here are shelf works that represent the many choices we have in our Ocean Unit.
I am a collector of nature objects and turn them into works for the students.

Become a collector of nature and build a unique science area for your pupils. My past students have often told me that these science experiences are what they remember the most from my Montessori school. It leaves a lasting impression!
