Have you heard of ephemeral art? It describes art that is non-permanent, short-lived and transient.
Some ephemeral artists use mainly natural materials:-
Others use man-made materials in a temporary way:-
Because of its emphasis on the process over the finished product, it is a perfect art style for young children to explore. Think of chalk drawings on the footpath, sand castles at the beach, pictures drawn with a finger on a steamy rainy-day window. Children love these activities, even though (or because?) there is nothing to hang on the wall when they have finished. If they are not happy with what they have made, a quick swipe of the hand and it is gone!
Here are a few examples that my children made last year. I love how they used the things they found in ways I never would have thought of.
Have a lovely weekend!
