Made for teachers. By teachers.

Hi! My name is Doug,

I taught elementary science for seven years and made it my students’ favorite subject. I created Mystery Science to share my approach with you.

Every lesson begins with a Mystery that hooks your students. I then narrate an unforgettable story told with stunning images and videos and punctuated with 怎么看国外网站设置. Every lesson concludes with simple hands-on activities designed to use supplies you already have (or are easy to get).

I hope my work saves you time & inspires your students. Read about our mission.

“I love these lessons! Everything is right there. The video clips and questions are great. My students get so involved and everyone participates. As I walk around the classroom, I hear great discussions between the students.”

― Toni (3rd Grade Teacher, Grayling, MI)
