Sparks have been flying in the Grade 10 Physical Sciences class this term as we’ve been investigating the static electricity hiding in objects around us.

We have seen that even a neutral object can be charged for a while if you put enough effort into it. When rubbing a ruler with a cloth, electrons are transferred from one object to the other. Because electrons have a negative charge, this transfer causes an imbalance in charge as there are now more negatively charged particles on the object. Therefore, the object has a negative charge. Once this imbalance in charge has been achieved, the object can be used to attract other neutral objects. When a charged object is brought close to a neutral object, it will induce a charge on the neutral object. This happens because similar charges repel, and opposite charges attract.

The Grade 10 Physical Sciences students investigated these concepts, which led to lots of interesting hairstyles!
