Field Notes
We are happy because we found many sea potatoes. Some still had saltwater in them so we could squish them. We had no problem finding the sea potatoes, there were sea potatoes every few feet on the beach, but on the rocks there were none. While we searched we could smell the salty ocean, we could hear other students yelling, and we could see the boats on the ocean. We were surprised because we expected the sea potatoes to be much bigger. The ones that we found were all relatively small.

Supporting Evidence
Photo of my evidence.
We knew it was a sea potato because it was fairly small. Sea cauliflower looks similar to a sea potato. We knew it was a sea potato, not a sea cauliflower because it had thin walls that we could see through. But sea cauliflower has thicker walls and look more like a brain.

We knew this is a sea potato because it was yellowish brown.

We knew this is a sea potato because sometimes they were attached to seaweed or shells. Sea potatoes can be found attached to other objects from the beach from time to time.
