The Science Photo of the Day lets me combine photography with science. You can use these as bell work, to stimulate scientific discussions, as practice researching information, or as a source of fun trivia. Some are easy. Others can be quite challenging. Often they come from whatever I happen to be doing that day. I try to post at least four or five Science Photos every week, but that can vary if I am in an area with no internet.
The most recent photo will not have an answer yet, but you can click on it to leave a guess or comment. For older photos, click to see the answer. Past photos are also listed in the right column on the category pages, making it easy to find Science Photos that tie in with what you are currently studying.
