For example, if you are interesting in researching lead in drinking water, consider:
WHO- The water in people's homes? In schools? Is a specific company or group of people involved?
WHAT- What causes the lead in the water? What is being done about this? What side effects (if any) does this cause? Does it impact health?
WHEN- Is this happening now? Has it ever happened in the past? Is it expected to continue into the future?
WHERE- The drinking water in a specific location- such as Flint, Michigan? Perhaps in a local area? Or another country?
WHY- Why is this happening?
