The big world is full of tiny surprises. Classes discover all things big and small while completing the second lesson of a five-part series comparing macro- and micro-objects. Learners collect items from around the room including things they can and cannot see with their eyes alone. They use magnifying lenses and microscopes to find the micro specimens in their collections.
