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).
