Title: What would
you name this report?
Observations: Summarize what we saw in the very beginning when we watched
what happened to the water drop when it landed on a flat surface.
Testable Question:
Mr.
Saeger has a roll of new pennies. What is a testable question about drops on
pennies of different ages?

hypothesis is an answer to the testable question. Don't use personal pronouns. Don't try to explain why you think one type of penny will hold a different number of drops.
Independent

independent variable?
Dependent
Variable:

the dependent variable?
Variables to
Control
Some of
the ways you did the lab might have changed the number of drops the penny held.
We listed several in your notes. List ten using bullet points
Procedure:
List
materials.
Give
step-by-step instructions so someone else could do the lab the same way you
did.
Bullet
points are OK.
There
are 5 to 10 steps depending on how you write them.
