Jennifer and I were contacted to lead an "end of year chalk experience" at a local elementary school. Originally, the plan was to be outside and chalk on pavement - BUT - then the rains came so on to PLAN B! We had the different grade levels of kids make a chalk aquarium, which as you see, they had an excellent time doing. We had about 350 kids move through our station in 3 hours. Thank goodness for adult HELPERS.
