I'll use the Kuiper Belt as an example for our research report outline. Research questions can fall into these categories:
INTRODUCTION QUESTIONS:
EXAMPLES/ What is the Kuiper Belt? Why is this area of space so unexplored?
HISTORICAL QUESTIONS (THE PAST):
EXAMPLES/ When was the Kuiper Belt discovered? Who was it named for? What ever happened to the Planet X theory?
EXCITING DEVELOPMENTS (CURRENT DEVELOPMENTS):
EXAMPLES/ What are the newest dwarf planets? What are thier names and what do they mean? How far away are these dwarf planets?
FUTURE QUESTIONS:
EXAMPLES/ Are astronomers still looking for Kuiper Belt Objects? How are they doing this? What do they hope to find? Will we ever send a space probe to this region?
UNANSWERED QUESTIONS:
EXAMPLES/ If 4 space probes passed through the Kuiper Belt, why don't we know more about it? Is there anything further out than the Kuiper Belt? How does the Kuiper Belt compare to the Oort Cloud? Are there different parts to the Kuiper Belt?
