Secondary 3- Static Electricity: Electron transfer
Secondary 3 students conducted a series of experiments to explore the concept of static electricity and electron transfer. The activities aimed to help them observe and understand how charged objects interact with other materials.
- Balloon and Small Paper Pieces:
- In this experiment, students rubbed a balloon on a woollen cloth and brought it close to small paper pieces. They observed how the balloon attracted the pieces, demonstrating the transfer of electrons from the cloth to the balloon, causing the balloon to become negatively charged.
- Plastic Ruler and Water Stream:
- Students rubbed a plastic ruler with a dry cloth and placed it near a thin stream of water from a faucet. They were amazed to see the water bend toward the ruler, proving the presence of static charge created by the movement of electrons to the ruler.
- Balloon and Hair:
- The third experiment involved rubbing a balloon on their hair. Students noted that their hair stood up or clung to the balloon, illustrating how electrons moved from their hair to the balloon, leaving their hair positively charged.
After completing these experiments, the students worked collaboratively to prepare a science report. They documented their observations, explained the science behind the phenomena, and concluded how electron transfer leads to static electricity.
This hands-on activity does not only enhance their understanding of physics but also help them practice scientific writing and teamwork skills. It also becomes school projection to prepare students tackling future challenges through structural thinking and collaboration.
