Year 4 had a problem to solve in science this week. How could we make the light bulb light up? With only a battery, a bulb and two wires, we had to investigate how to make light. We discovered that it was important how we connected the battery and that the wires had to make a complete circuit. Next week, we are going to take this investigation further. Is there anything else we could use instead of a battery to make the bulb light up?
