My name is Jessie Hagadorn. I am an educator at Heritage High School.

I am teaching Biology and Environmental Science for the 2021-2022 school year.
I received my undergraduate degree in Cellular/ Molecular Biology from Humboldt State University and my teaching credential from California State University San Marcos. I love helping students learn more about the natural world and seeing their confidence and curiosity grow!

I use Canvas as the learning management system for Biology and Environmental Science courses. Students should log into Canvas daily to make sure they are on track with our class by viewing the "Overview" page for that week. Students should also review the Canvas "Grades" page to see their most accurate grades and updates on assignments that need improvement. If parents/guardians would like to create an account that pairs with your student to track their progress, please follow the instructions in this link.  

Access our Canvas courses with the links below. The Canvas courses are publicly viewable.

I also use the Remind app with my classes for announcements and as a supplemental form of communication. If parents/guardians would like to join our Remind groups to receive these notifications, please follow the instructions in the Syllabus.
