Question

Observation: Light bulb did not light. A hypothesis is a potential answer to the question, one that can somehow be tested. Hypothesis: The light bulb is blown. If the bulb is replaced and it lights, then this hypothesis is validated. If the bulb does not light, then the hypothesis is invalidated. Experiment: Replace the bulb. Result: New bulb lights up. Conclusion: The hypothesis is validated. The bulb was blown. What are you measuring in this experiment? hypothesis is specific but not measurable. What are your controls for this experiment? How was this experiment performed, including testing the controls?

Answer 1

Essentially what this means is that the previous light bulb was blown.There was no problem in the circuit.Hence when we replaced the old bulb with a new one,it lights up.

What we did here is to test the hypothesis.Join a new bulb in series connection and saw whether it lights up or not.

In this experiment we are measuring whether the light bulb was blown or there was a problem in the circuit.

If the new bulb did not light up then we would have said that  hypothesis can not be tested as there is a problem in the circuit itself.This is how hypothesis are validated or invalidated.

Hope it helps.
