This week in Year 6, our budding scientists embarked on an electrifying experiment to investigate the relationship between bulbs and brightness in a circuit!
The challenge? To see how the number of bulbs in a circuit affects the overall brightness. Equipped with batteries, wires, and an assortment of circuit components, the students were eager to put their scientific thinking caps on.
Diligently following a scientific method, they meticulously constructed circuits with varying numbers of bulbs. With each creation, they carefully observed the level of brightness produced.
The results were illuminating (pun intended)! The students discovered that as the number of bulbs in the circuit increased, the overall brightness decreased. This is because the same amount of electrical energy is being shared amongst more bulbs, resulting in a dimmer glow for each.
But our young scientists weren’t done yet! They took their exploration a step further by creating a table to record their observations and drawing clear diagrams of their circuits. This meticulous documentation will be crucial when they come to write their scientific reports, explaining their findings and the scientific concepts behind them.
