I've done all the work for you! Each date has a STEM-related discussion-starter that you can use as an introduction, conclusion, or fill-in when needed.
Each day includes what happened on that date, a bit of information for your students, an appropriate image, and a thought-provoking question for discussion.
You can even post this as a journal-entry prompt!
Each date is connected to further information links for your use, or a student's independent learning.
Follow me to see each of the months evolve as I complete the entire year. (My daughter, who teaches middle school STEM needed something like this, and this retired Mama stepped up to the plate!)
