Science is one of the richest seams the Bing quiz mines, partly because so many homepage photos are of natural phenomena. If the image shows an eclipse, a volcano or a deep-sea creature, you can usually bet a science question is coming. Here's how to read them.
The fields it draws on
Astronomy and space, biology and the human body, geology, weather and chemistry all turn up, almost always anchored to the day's image. A photo of the night sky tends to bring planets or constellations; a glacier brings questions about how ice and landscapes form.
Example questions
You might get "Which planet is known as the Red Planet?" (Mars), "What gas do plants take in during photosynthesis?" (carbon dioxide), or "What is the largest organ in the human body?" (the skin). When a natural process is pictured, expect a how-does-it-work angle.
Reaching the right answer
These questions are written for a general audience, not scientists, so a single search usually settles them. Name the subject from the caption, ask for the specific fact, and check the figure against a reliable reference if a number or superlative is involved.
