One day in science, Brittany's class was doing an experiment. Brittany didn't clear off her desk before the experiment.
Oh well. I'll just do the experiment anyway.
This desk is messy!
Brittany started doing the experiment.
Then, because there was so much stuff on the desk, the dangerous chemicals in the experiment spilled on Brittany and burned her skin. She learned that she should clear off her desk before the experiment and keep it clean throughout it so that she can do the experiment successfully.
One day in science, Glenda's class was doing an experiment. Glenda made sure to clear off her desk before the experiment.
I'm all ready to start the experiment!
Glenda started doing the experiment.
This is fun!
Glenda finished the experiment safely because her desk was clear during it. Since it was clear, she had space for the chemicals and none of them spilled.
