Hello again,

Here's what your notebook should look like for lessons 12 and 13:

We also wrote two more definitions on pages 6/7. They are:

    Control variable:  any variable in an investigation that stays the same

    Petri dish:  A glass/plastic oval dish used to culture (or grow) cells

And finally, we set up a new investigation where we swabbed our fingers and are growing bacteria!
