Mystery Science

Mystery Science (K-5) is a site with “open-and-go lessons that inspire kids to love science.” 

This Subscription is not available to HCOS Registered students.

Mystery Science Explained
  • Hands-on — lead students in the doing of science and engineering.

  • Less prep, more learning — prep in minutes, not hours. Captivate students with short videos and discussion questions.

  • Easy to use – Homeschooling parents can use this site easily.

There are three levels to Mystery Science:

  • Mini-lessons are for families who have very little time or struggle to fit Science in at all. 5-15 min./week

  • Core lessons are for families who have more time for hands-on Science. 40-60 min./week

  • Anchor Layer is for families who want to take their Science lessons to the next level. 2 hrs./week

Every lesson begins with a Mystery that hooks your students. Then, there is a narration of an unforgettable story with stunning images and videos punctuated with opportunities for discussion. Every lesson concludes with simple hands-on activities designed to use supplies you already have (or are easy to get).
