Teaching students about electrons’ negative charge involves introducing them to the concept of subatomic particles and their properties. Students should understand that atoms are made up of protons, neutrons, and electrons. Electrons have a negative charge, while protons have a positive charge, and neutrons have no charge.

To demonstrate the negative charge of an electron, the students can carry out small experiments like rubbing a balloon on their hair to create static electricity. This electricity is created by the movement of electrons between the balloons and the hair, and the balloon’s negative charge attracts the positively charged hair.

Another way to teach students is by using the analogy of magnets, where the opposite poles attract and the same poles repel. Similarly, electrons are negatively charged and, therefore, are attracted to positively charged particles like protons but repel other negatively charged particles.

Overall, teaching students about electrons’ negative charge involves introducing them to the concept of subatomic particles and their properties through experiments and analogies to enable them to understand.
