Students will enjoy connecting batteries, wires and bulbs in various combinations to try to make bulbs light. Snap-on wire clips enable students to make connections between the batteries and bulbs quickly. A chart of various arrangements for connecting the batteries and bulbs is provided. The student studies the chart, predicts which arrangement will light the bulb and which will not, then connects the real batteries and bulbs (following the diagrams) to prove or disprove original predictions. Purchase size "D" batteries separately.
