Science Experiment Drawing

The other week my 4 year old was very serious about doing one of her own science experiments.  This experiment was a simple setup of a bottle of water and placing a small bath toy in the bottle and watching it float.  Nothing complicated, but at 4 years old, it's cool seeing her design her own experiments.  A couple of days later, she drew this:

She drew out the procedure of her experiment!  And she did a better job than I'd most likely do!  In addition, she got really mad when a week later I dumped out the bottle and washed it.  She claimed it was her science experiment, and I thought she was done.  Apparently not!  We had to refill the bottle and put the toy back in.  So there's a water bottle with a bath toy in it sitting on the kitchen counter for who knows how long!!!
