Professor Big-Hair and Professor
Bee-Hive have a problem. They can’t do any work, because their alarm clock is
constantly ringing and the off switch is broken. Professor Big-hair thinks if they wrap it in a
sheet, they can muffle the sound so they won’t be able to hear it. Professor Beehive thinks they should do an experiment
with different materials, to see which one will muffle the sound best. She says they should wrap the alarm clock in each of
the materials, and see if they can still hear it ringing.
We planned a fair test. We changed one thing (the material)
and kept everything else the same.
We then carried out the experiment
