Classroom Boggle- for kids who finish early! First off, I LOVE boggle!! Secondly, this is an awesome way to keep kids busy if they finish early and it would be easy to change some letters at the end of each day or the next morning!
Try this science experiment with children over the course of several days. Fill up 4 vases with different coloured water and put 1 white carnation in each one. Watch the flowers over the next four days change to the colour of the water.
