The video tutorial demonstrates how to create a fossil cast using colored clay and a clam shell. It outlines the materials needed and provides step-by-step instructions to form a replica of the shell's outer surface. The process involves pressing the shell onto the clay to capture its details, resulting in a cast model.

• Colored clay and a clam shell

• Colored clay and a rock

• Sand and a clam shell

What is the first step in creating a fossil cast?

• Remove the shell from the clay

• Color the clay

• Press the clay to make a plain surface

• With the outer surface facing down

• With the edge facing down

• With the shell standing upright

What is observed after removing the shell from the clay?
