Welcome to Biology!

My name is Pete Rietveld and I have been teaching Science since 1992.

Notes, Labs, Question Sets, Articles, Power Points, Etc. Here you will find copies of most material that is covered in class. I will add new items as they are presented in class. Feel free to copy or print out any material found here. This site has EVERYTHING!!!

Email account for turning in student work, projects, etc. I NEVER use this email account for personal messages and therefore will NEVER respond to messages sent here.

For Regular Biology


Email account for corresponding about student issues, parent issues, etc. This is my Rochester Public Schools professional email account. Projects and student work should NOT be sent here. I WILL respond to email messages sent to this address.


If parents wish to contact me regarding specific issues that arise, I DO prefer to discuss them via telephone instead of email. Much faster and misunderstanding is usually held to a minimum. I have learned that email messages can take on a life of their own. I am usually available from 6:30 am to 7:35 am every morning. Since I teach night school, I am RARELY at school after 3:15 pm. Therefore, mornings are best if you need to reach me. My direct classroom number is:
