After getting quite a bit of feedback, I am making a change to the Science Photos. Quite a few people said that every day was too much, and did not give them enough time, so I am going to try doing a new science photo once a week instead.
If you are not familiar with my Science Photos, I will post a new photograph with a science question each week. The photos will be posted here and on my Happy Scientist Facebook page. The next week, I will post the answer, along with a new photo and question.
Some of the questions will be simple, while others may take quite a bit of research to answer. Subscribers are welcome to post your answer in the comments, but they will not appear on this site until I approve them (which cuts down on spam, off topic comments, etc.) If you are not a subscriber, you may post your answer on the Happy Scientist Facebook page.
With thousands of pages, it can be a challenge to find exactly the science you want.
