In this lab activity, we'll explore the fascinating world of electric charges using balloons! Everything around us is made of atoms, which contain positively charged protons, negatively charged electrons, and neutral neutrons. Usually, things are neutral because they have an equal number of protons and electrons. However, when we rub a balloon on our hair, we're actually transferring electrons from our hair to the balloon. This gives the balloon a negative charge and leaves our hair with a positive charge. Opposite charges attract, which is why the balloon might stick to the wall! Like charges repel, which is why two negatively charged balloons will push away from each other.
This activity helps us visualize these concepts and understand how static electricity works in our everyday lives. Get ready to experiment and see the power of electric charges in action!
