THE INITIAL QUESTION IN THE TITLE IS ANSWERED THROUGH SIMPLE EXPERIMENTS FOR CULTURALLY DISADVANTAGED CHILDREN IN ELEMENTARY SCHOOL. MUSCLES, RUNNING, WATER, WIND, STEAM, FAST BURNING AND ELECTRICITY ARE FOUND TO "MAKE THINGS GO." USING THESE BASIC DISCOVERIES, VOCABULARY IS BUILT UP BY WORKING WITH DIFFERENT WORDS RELATING TO THE EXPERIMENTS. A STORY IS TOLD IN TERMS FAMILIAR TO THE CULTURALLY DEPRIVED CHILDREN. THE BOY IN THE STORY MAKES THE DISCOVERIES SHOWN IN THE EXPERIMENTS AS HE PLAYS WITH CHRISTMAS TOYS.
