Real Science Teaching. Real Classroom Experience.

I’m Amy Brown, a veteran high school biology and chemistry teacher, wife, and mom who understands the daily reality of lesson planning, grading, meetings, and everything in between. I know what it feels like to have too much to do and not enough time to do it.

After decades in the classroom, I’ve created rigorous, classroom-tested biology and chemistry resources that save you planning time while still delivering strong, meaningful science instruction. Every lab, activity, and lesson is designed to move students beyond memorization and into real scientific thinking.

If you want your students excited about science and thinking deeply without spending your entire weekend planning, you’re in the right place.

Biology Warm Ups and Bell Ringers for High School Science


biology warm ups and bell ringers interactive notebook examples for high school biology classroom management

Biology warm ups and bell ringers are one of the most effective classroom management tools for high school science teachers. These short, focused science warm ups help students settle quickly, reinforce key biology concepts, and create a productive learning environment from the moment class begins.

If your class starts with distractions, side conversations, and wasted time, biology bell ringers can completely transform those first few minutes into meaningful learning.

I began using daily biology warm up activities to improve focus, reinforce content, and establish consistent classroom routines. The results were immediate. Students entered class, opened their notebooks, and got to work right away.

Using biology bell ringers consistently helped reinforce content, improve student engagement, and create a calm, productive start to every class period. Students also use warm ups to review complex topics throughout the year. For example, these DNA, RNA, and protein synthesis warm ups help students review protein synthesis and molecular biology concepts in a short daily activity. You can view examples of my biology bell ringers and how they are organized by unit in my TpT store here.

What Are Biology Bell Ringers?

Biology bell ringers are short warm up activities that students complete at the beginning of class. These science warm ups reinforce previously learned material, introduce new topics, and help students transition quickly into learning mode.

These activities also work well as life science warm ups or general science warm ups in upper middle school and high school classrooms.

Biology warm ups and bell ringers help teachers:

• establish consistent classroom routines
• improve student focus immediately
• reinforce biology content daily
• increase student retention
• improve classroom management

For high school science teachers, bell ringers are one of the simplest and most effective instructional tools available. Biology warm ups are especially effective because they provide daily review, reinforce key concepts, and help students retain information long term.

Why Biology Bell Ringers Improve Classroom Management


You can turn this chaotic time of your class into a time of meaningful learning. Using bell ringers establishes a daily routine of having your students complete thought provoking and problem solving tasks during the first 5 minutes of the class.  Once the routine is established, students will enter the room and get right to work on the warm-up or bell-ringer activity. These warm-ups are designed to take 5-7 minutes to complete. It settles the students and provides the instructor a few minutes to carry out the tasks required at the beginning of a class.

It took a bit of time, but I now have sets of bell ringers for every chapter of a traditional high school biology class. Since most biology or life science textbooks are generally divided into ten units, I organized my warm up activities in the same fashion. For example, my ecology warm ups and bell ringers include activities that help students review topics such as food webs, energy flow, and ecological relationships.
  • Unit 1:  Introduction to Science (Scientific Method, Graphing, Chemistry, Biochemistry)
  • Unit 2:  Cells
  • Unit 3:  Ecology
  • Unit 4:  Genetics
  • Unit 5:  Evolution
  • Unit 6:  Microorganisms and Fungi
  • Unit 7:  Plants
  • Unit 8:  Invertebrates
  • Unit 9:  Chordates
  • Unit 10:  The Human Body
If you would like ready to use biology warm ups and bell ringers for your classroom, you can view all biology bell ringer sets in my TpT store here. These activities cover every biology unit and are designed to save preparation time while reinforcing key biology concepts.

The pages are printed landscape style. The pages look best if printed in color, but also look great if printed in black/white. Each activity is one-half page in size. Two identical warm-ups are printed per page in order to conserve paper. In this time saving classroom management strategy, all you have to do is print the pages and cut them in half.

These half-page activities can be collected and quickly graded, or you might want to have your students keep a daily warm-up notebook. Many teachers also incorporate these activities into biology interactive notebooks, which provide students with an organized way to review key concepts throughout the year. These warm-ups will make excellent additions to your interactive notebooks. An added benefit ... The completed warm-up notebook makes an excellent review for the semester exam!

Frequently Asked Questions About Biology Warm Ups and Bell Ringers

How long should biology warm ups take?
Most biology warm ups and bell ringers are designed to take about 5 to 7 minutes. This gives students time to settle into class, review important science concepts, and begin working before the main lesson starts.

What are biology bell ringers?
Biology bell ringers are short activities students complete at the beginning of class. They can be used to review vocabulary, reinforce content, practice science skills, and establish a consistent classroom routine.

Can biology warm ups be used in interactive notebooks?
Yes. Biology warm ups work well in interactive notebooks because students can keep their daily review activities in one organized place. The completed notebook can also be used as a study tool before quizzes, tests, or semester exams.

Are these warm ups useful for life science classes?
Yes. Many biology warm ups also work well as life science warm ups for upper middle school, introductory biology, or general high school science classes.

I now have 41 biology bell ringer sets available in my TpT store. You can view them all here.

They can be purchased individually, and they are arranged into four large unit bundles:

I hope these work as well for you as they did for me.

    Great ideas in here! It sounds like you and I have similar views on classroom management. I also view it as a strength of mine. I have had wonderful luck with "Do Nows." I would never go back to not using them in class. They are a great way to review key information and introduce new information. Thank you for sharing your ideas!
