Citizen Scientists
You don't need a lab coat to do real science. Every year, thousands of volunteers count birds, track butterflies and record when the first flowers bloom in their neighbourhoods. They are called citizen scientists.
Scientists can't be everywhere at once. By collecting observations from many places, volunteers help researchers spot large patterns, such as changes in when some birds arrive each spring.
Of course, data from volunteers must be checked. Many projects train participants, ask for photos and compare reports to catch mistakes. With these steps, a single backyard observation can become part of a study that spans a whole continent.
