Meet Your Teacher
Mr. Riz has spent 46 years teaching chemistry. Three governors have recognized him for excellence in teaching.
When former students approached him about adapting his curriculum for homeschool families, ChemExplained was born. More than a decade later, the foundation hasn’t changed. Every lesson is still taught by one teacher who believes chemistry doesn’t have to be intimidating, only explained in words the student can understand.
