Critter Rocks

These fun science activities are easy to do. If you live near the seashore or are going to visit the ocean collect some interesting shells for this project. Craft stores also sell seashells that can be used for this activity.

In these easy science activities you will be creating your own sedimentary critter rocks. The gates and fort at St. Augustine, Florida are made of seashells and other crushed materials similar to your seashell rock.
