Material and instructions
If you live in an area
with access to shells, this can be a project for you. Collect
samples, do close observations, record geographical and physical
data of what you collect.
Focus on interesting points and try to find a reason for everything
that you observe.
Study the function and the construction of the shell.
This project guide suggests two
specific questions for studying shells by students. The first question
is studying the sound that we hear from large cone shape shells. The
second question is the chemistry of a shell and its reaction with vinegar
(as an acid).
