I have always had a difficult time finding things to do for Groundhog art so was very happy to come across this fun shadow art on Artsonia (http://www.artsonia.com/).
This activity works for any primary grade. We started the lesson by discussing Groundhog day and about how shadows are formed.
For the background, you could choice to either have the kids draw and colour in or paint. For the example paint was used. The kids had the choice of drawing or painting a pond and have themselves skating or just leaving it white so they would be playing in the snow. We discussed the element of Space and making trees smaller as they get further away and also the horizon line. The sky needs to either have a sun or a yellow sky to give the illusion of it being sunny in order to have a shadow.
Once background is completed, kids draw a picture of themselves on a separate piece of paper. They can either colour it in and/or add snowsuit, mitts, hat with construction paper. They next cut out their little person, trace it on black paper and glue the person and the shadow onto their background (making sure that the shadow is their mirror image)
Happy Groundhog Day!
