Snail Surface preference
Test the surface preferences of snails. Students may place an active snail between a piece of
foil and piece of waxed paper to see which way it moves. Test several times to see if it chooses
the same path each time and truly has a preference. Test other surfaces as well.

Slugs and Snails
Bring in a slug (or a picture) to compare to snails. If students ask, slugs are not snails that lost
their shells - they are a separate species of mollusks who live their entire lives without a shell.
Draw a picture of a snail.
