Put on your Sherlock Holmes hat! A Forensic Science and Detective Lesson Plan is perfect for elementary students, because mysteries are always fun to solve. There are tons of detective activities for all subjects (math, reading, writing, science, art and even exercise!). So let’s go study fingerprints, make some invisible ink and solve some mysteries (while “secretly” working on math and reading comprehension!). And don’t forget to join our Facebook Group and “like” our Facebook Page, so you won’t miss out on any of our educational fun!
If you are looking for a great way to keep your children entertained for hours, get your big kids this Mysterium Board Game (it is like a massively improved version of the board game Clue from our childhood!). Or the book Brain Games: Criminal Mind Puzzles is fabulous too (for an independent activity.)!
