When Jahim predicted why the light did not come on, he was using the part of the scientific method known as "forming a hypothesis."
Here's a breakdown of the scientific method steps:
1. **Observation:** Jahim observed that when he turned on the light switch in the living room, no lights came on, unlike the rest of the house where lights worked.
2. **Forming a Hypothesis:** Based on his observation, Jahim made an educated guess or hypothesis that the light in the lamp went out, causing the issue.
3. **Planning an Experiment:** After forming his hypothesis, Jahim planned to test it by replacing the bulb in the lamp to see if the light would come back on.
4. **Conducting the Experiment:** Jahim replaced the bulb in the lamp, which was his experiment to test the hypothesis.
5. **Observing the Results:** Once Jahim replaced the bulb, he observed that the light came back on, confirming his hypothesis.
Therefore, in this scenario, Jahim used the scientific method by forming a hypothesis to explain why the light did not come on initially.
