Sand Stepping

Prepare a tray of tempera paint mixed with sand and dish washing soap.
Place the paint at one end of bulletin board paper; then place a dishpan
of water and an old towel at the other end of paper. Have each child take
turns stepping in paint and walking across bulletin board paper. Have
 them rinse feet and dry them. Label each child's foot prints with their name.
 Paint glue on the areas of the paper surrounding the footprints; then sprinkle
 sand over the glue.  Once this is dry, hang on bulletin board for all to see!

Beach Balls Bulletin Board Displays

Set up a small round baby pool.  Cut white bulletin board paper into a class supply
 of circles sized to fit the bottom of your pool.  To try this jumbo painting experience,
 a child puts on an art smock and picks up a beach ball.  Using either squeeze
 bottles or paintbrushes dipped in washable paint, he puts some paint on the ball.
  Then he places the ball in the pool.  With the help of an adult helper, he moves
 the ball around by gently tilting and moving the pool.  Remove the paper and lay
 it flat to dry.  When everyone has done some beach ball painting, you'll have
 a collection of colorful beach balls do display throughout your classroom.
