Make a Corn Mosaic
Make a corn mosaic with dried, colorful "Indian corn," or color whole dried corn kernels with felt-tip pens (feed corn available at pet or feed stores). Glue corn kernels on construction paper to make colorful kachinas, animals, cacti, constellations, etc.
Make Flower Pot Drums
Make drums of flower pots covered with burlap (use burlap for the drum skin, too, tied with twine). Decorate with felt-tip pens. Or use coffee cans with drum skin of crumpled paper sacks, tied with twine.
Have a Drum Session
Someone begins a beat, another joins in, soon everyone is banging away to the rhythm. A chant can be introduced to the drumming. If few drums are available, or for variety, use spoons, pans, etc.
