Marianne Aiken
Marianne Aiken

I began teaching Science in Chicago  35 years ago. I graduated college with a Bachelor’s degree in Zoology and Secondary Education and later earned a Master’s degree in Curriculum and Instruction.

I have attended the University of Oregon Marine Biology Program, Fermi National Laboratory Institute for Teachers, Space Camp for Teachers in Huntsville, Alabama, Inquiry for Science Teachers and most recently Mission Cognition.

I knew I would become a teacher when I held “summer school” in my parents’ basement. In high school, I had a science teacher who was a role model and I knew then I wanted to make a difference in children’s’ lives just like my teachers had done for me.  I love teaching because each day brings its own rewards and challenges.
