The children have been very engaged in exploring dry, damp, wet and VERY wet sand. We have a sensory table full of sand in our art studio and every day we explore the sand. Sometimes we play with the dry sand...usually the children ask the teachers to add water to it. Sometimes we add just enough water so that we can create molds and sand castles. Sometimes we add a lot of water and the children explore mud and create "rivers" running through our table. This has been a daily experience...the sand is always open and the children often enjoy exploring this during drop off time.
