I. Title: Penny Drop Lab

II. Purpose: The Purpose of this lab is…

III. Hypothesis: The penny will hold an average of ______drops of water.

IV. Materials: □ List vertically □ Do not number □ Be specific □ No Commas

V. Methodology: □ Write in past tense □ Do not use personal pronouns □ Write in paragraph form □ Do not write like a list of commands.
