Technology Serves as Practical Prop for Children's Literature
In one of our favorite books, "The Doorbell Rang" by Pat Hutchins, 2 children share 12 cookies. Each time more children arrive at the door, they ring the bell and the cookie division problem changes. For props, we use a 9-volt battery and a door buzzer (available at electronics stores). Every time we read, “as the doorbell rang", one of the readers serves as prop technician by touching the wires to the terminals of the battery, completing a simple circuit. When the door buzzes, smiles spread around the room. Everybody wants a turn with technology.
Children as young as 9 years have been involved with building simple and inexpensive underwater robots, such as the one shown above. The basics of "float and sink" activities can be expanded with PVC pipes and elbows and combined with wiring circuits to produce a working machine. Since less than 5% of the ocean has been explored, today's young students may grow up to find many jobs available in the marine technology industry.
