They’re lovely, but why are these mushrooms growing in a Northern Indiana back yard in late August? Science teachers know where to go to investigate weather-related questions: to the weather underground (wunderground.com). You can see at a glance that it was a cold and rainy end-of-August for zipcode 46530. (Click on these graphs to get to the original source.)
I wonder what the whole summer looks like? Wunderground can tell you. It seems that it’s been fairly close to the same temperature since May.
Weather underground is a great way to turn our day-to-day or seasonal observations into an occasion for data-driven investigation. Consider visiting wunderground.com; you can ask the next question:)
