A Conundrum is a confusing and difficult problem or question. Students learn to open their brains and think in less literal terms while solving a challenging riddle by asking yes or no questions. The answer is based around a real life instance of "human ingenuity" and includes links to Youtube film clips, student data sheet and recommendation for using a Myth Busters episode as a follow-up. A fun way to improve students skills in one of the NGSS eight practices of Science and Engineering. Proven effective for over 20 years in the fourth grade but can be used with almost any grade 2-12.
