Science Milestones: The Achievements and Discoveries of the World

In this series, Science Milestones, I’ve chosen architects, engineers, inventors, and scientists whose discoveries and advancements have made a significant difference in our lives or who have advanced our understanding of the world around us.

Science Milestones

Each month, to honor these amazing people, I will share some unschool-style learning guides or unit studies featuring basic facts about the person, questions for discussion, and places to read, watch and otherwise learn more.

These have been a ton of fun to create! I’ll continue to add new science milestones in birthdate order here, so pin, bookmark or share this page to stay updated
