Explanation:

Step1: Analyze the scope of each topic

• "how to observe astronomical phenomena" covers all kinds of astronomical events, so it's the broadest.
• "how to observe a solar eclipse" is a specific type of astronomical phenomenon, so it's narrower than the first one.
• "how to observe a solar eclipse using a pinhole camera" is a very specific method to observe a solar eclipse, so it's the narrowest.

Step2: Order from broadest to narrowest

Arrange the topics based on their scope: broadest first, then narrower, then the narrowest.

Answer:

broader: how to observe astronomical phenomena
middle: how to observe a solar eclipse
narrower: how to observe a solar eclipse using a pinhole camera
