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.

Interactive Notebooks Make Teaching Viruses and Bacteria a Snap

Do you need a new/better routine for your classroom?
Are you looking for a way to review and reinforce the volume of biology information you must cover?
Looking for quality warm up activities or homework assignments?

I use warm ups or bell ringers every single day as a method of getting my students settled, on task, and ready to learn.  These activities are short, and take only a few minutes to complete.  Once students are used to the routine, they will enter the classroom and get right to work.  I like that the first few minutes of class are spent "getting down to business."

There is such great versatility in how you can use these interactive notebook pages.  As already stated, they are perfect for turning the first chaotic minutes of class into a time of meaningful learning and reinforcement.  I also use them for homework assignments, and they are perfect to leave in my sub folder in case I am absent.

If students are required to keep them in a notebook, they have a perfect study guide for the unit test and semester exams.


This is the 7th set of warm up activities posted to my TpT store.  (Check out the blog archive in the right side bar to see previous articles.)  This set covers "Viruses and Bacteria."  The set of 23 student pages covers all the topics found in a typical first year biology textbook.

The student 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.  Simply print the pages and cut them in half.


All teacher pages are set up in this style.  The student activity is on the left, and the answers are on the right side of the page.  Print these pages for your teacher notebook.

This super idea was the brain-child of Karol Steele (Mrs. S on TpT).  Many thanks to Karol for organizing, compiling, and publishing this fun eBook.


Holiday giving ... With a Science Twist!!

Your students will have a blast with this dichotomous  classification key!

(It's educational ... sort of ....)

Very rarely in my high school biology classes do we have the time to devote to a holiday activity.  I make an exception each year for this fun, but very important activity.  I do this activity each year to remind my students of the importance of community service and “giving back” to our community. 

The purpose of the activity is very simple:  To put together stockings of candy and Ziploc bags of toiletries that can be donated to a local charity.

This is a free download from my TpT store, and is suitable for grades 5-12. Click here to download.


Just before Thanksgiving, I place a donation box in my room.  I explain to my students that I am collecting their spare change for a service project that we will do just before school is out for the holidays.  I talk briefly about being thankful for what we have, and that we have an obligation to help others who are less fortunate than us.  I ask them to place their donations in the collection box whenever they have a bit of change in their pockets to spare.  I encourage them to give what they can, and that all donations are a personal and private matter.   I accept the donations for about 3 weeks prior to the activity.  The students are not allowed to ask each other how much they donated, etc.  I use this change to purchase the items needed for the activity.  

Students will use the dichotomous classification key to identify each of the candies and each of the toiletries seen above.  Each item has been given a very special and unique name for this fun activity!  Ok, I'm going to admit that the science is a little "shaky" in this activity, but the students deserve a break from time to time, and they do love doing this activity.



The end result is that you have stockings of candy and bags of toiletries to donate to a food bank, a nursing home, a homeless shelter, or other charity of your choice.


I hope you have a wonderful holiday season with your students and families!



Secondary Smorgasbord: A Buffet of Resources for Secondary Teachers

The Secondary Smorgasbord Theme of the Week??
Free and Fabulous!!

I am super excited to be participating in a new monthly blog hop / linky for secondary teachers.  This terrific idea is the brainstorm of two friends Darlene Anne Curran (The ELA Buffet) and Pamela Kranz (Desktop Learning Adventures).  I was fortunate enough to finally meet both new friends this past summer at the TeachersPayTeachers convention in Las Vegas.

The idea behind this blog hop is to provide you secondary teachers with some new ideas, tips for your classroom, free teaching materials, and anything else we can think of.  So welcome to the first installment of the Secondary Smorgasbord!  The theme for this month is "Free and Fabulous!"  Be sure to click on the links in the first paragraph of the post so that you can grab all of the awesome free teaching materials.

What is on the smorgasbord menu from Science Stuff?  I have decided to highlight two freebies that I have in my store.  Both are simple one-page references tables, but I have used both of these in just the last week!  If you are a biology or a chemistry teacher you know that both of these play a very important role in our classes.  I know you already have these tables, but I have spruced them up to make them attractive for our students.




For the Biology teachers:  Here is a chart of all 64 mRNA codons and the amino acids they code for.  This is a must-have during your unit on DNA, RNA and Protein synthesis.  (Click image or red text to download freebie.)




For the Chemistry teachers:  This is a table of electronegativities.  This is a must-have during units on the periodic table and bonding.  Click image or red text to download freebie.)

Again, be sure to check out all the posts / freebies by clicking the links in the first paragraph.  I hope you find something you can use!  Be sure to watch each month for the Secondary Smorgasbord Buffet of Resources!




Evolution and Classification Warm Ups and Interactive Notebook Pages

Do you love teaching about evolution or dread it?


I am the biggest biology nerd ever, so I love ALL of biology.  But I really, really, really love teaching about evolution, followed up with classification.  My first year biology students have very poor (and uninformed!!) ideas and knowledge about evolution.  For many of them, it is the first time they have been taught about it.  Others come with a lot of misinformation.

This makes for such a fun teaching situation!  Just for kicks, ask your students about their opinions on the topic of evolution BEFORE you teach them the unit. I am always amazed at their misconceptions and poor knowledge base.  When you have finished teaching your unit, ask the students again about their opinions.  I love that over the course of a couple of weeks the opinions of many will be changed, and the knowledge level of all has been increased.

And the best part?  There is never a dull moment in class.  I love the discussion and the questions and the arguing!  I love to see the wheels turning in their brains.

Since this material tends to be new for most of my students, I developed a set of 61 warm ups / bell ringers / interactive notebook pages to use during the unit.


There are so many ways to use these pages.  I have my students keep a "Biology Warm Up Notebook."  It is a perfect way to review and reinforce material from the previous day, and it is a fantastic classroom management tool. 

My students come in, grab the warm up and get right to work. By the time I have finished taking roll, answering questions, dealing with the "stuff" that we teachers always have to deal with, my students are settled down and are already hard at work. There are too many pages to be completed in class, so I often use them as homework assignments, and review guides for the unit test.

Keeping a "warm up" notebook provides a perfect way to
review for the semester exam or end of course testing.


Below is a table of contents.  The 61 pages include all of these titles.



Here is a look at format.....



These warm-ups pair well with other classification and taxonomy activities for middle and high school biology, including dichotomous key and cladogram activities.

As always, I hope you are having a terrific year with your students.

DNA and RNA and Protein Synthesis Warm Ups or Interactive Notebooks for Biology


DNA RNA protein synthesis warm ups biology activities interactive notebook pages

What Is DNA, RNA, and Protein Synthesis?

DNA stores the genetic instructions used by cells to build proteins. During transcription, a section of DNA is copied into RNA. During translation, the RNA sequence is used to assemble amino acids into a protein. Together, these steps form the process known as protein synthesis, which allows genetic information to control cell structure and function.

Teaching DNA, RNA, and protein synthesis can be challenging for students because these processes occur at a microscopic level that is difficult to visualize. Concepts such as nucleotide structure, transcription, translation, and gene expression require students to imagine processes they cannot see directly.

Short, focused biology classroom activities can help students build a stronger understanding of how genetic information flows from DNA to RNA to proteins during transcription and translation.

These DNA, RNA, and protein synthesis warm ups provide quick classroom activities that reinforce key concepts such as nucleotide structure, nitrogen base pairing rules, DNA replication, transcription, translation, and gene expression. Each activity takes only 5–7 minutes, making them ideal for warm ups, bell ringers, review activities, or short formative assessments.

If you would like the complete set of DNA, RNA, and protein synthesis warm ups, you can find the full resource in my Teachers Pay Teachers store.

Understanding DNA and RNA Concepts

Students often struggle to understand how DNA structure connects to replication, transcription, and protein synthesis. Activities that require students to draw, label, and analyze molecular structures can make these abstract processes much easier to understand.

In these activities, students work through pages that help them visualize:

• DNA structure and nucleotides
• nitrogen base pairing rules
• DNA replication
• RNA transcription
• translation and protein synthesis
• gene expression and mutations

By actively drawing and labeling DNA and RNA structures, students move beyond memorization and begin to understand how genetic information is stored, copied, and expressed in cells.


DNA transcription activity page and student sample biology warm up


Students complete DNA structure and replication pages as well as RNA transcription and protein synthesis activities to reinforce key DNA and RNA concepts. Drawing and labeling molecular structures helps solidify learning.

DNA vs RNA Classroom Activities

Teachers often look for a DNA vs RNA activity to help students compare the structure and function of these two important molecules. Activities that require students to examine nucleotides, analyze nitrogen base pairing rules, and identify structural differences between DNA and RNA help students clearly understand how genetic information is stored and used in cells.

Several pages in this set help students compare DNA and RNA structure and function. Students examine nucleotide components, analyze base pairing rules, and identify the differences between DNA and RNA molecules.

These DNA vs RNA activities help students understand how DNA instructions are transcribed into RNA before being translated into proteins. When students see how these processes connect, the steps of protein synthesis become much easier to understand.

DNA, RNA, and Protein Synthesis Classroom Activities

DNA RNA protein synthesis warm up pages for bell ringers and interactive notebook

These DNA, RNA, and protein synthesis activities work well for:

• warm ups or bell ringers
• interactive notebook pages
• exit slips
• homework assignments
• tutoring and review
• short daily quizzes

A completed warm up notebook can also become a valuable semester exam review tool for students.

Because each page focuses on a specific concept, teachers can easily choose activities that match their current lesson. Many teachers also use these pages as interactive notebook activities so students can build a reference notebook of important genetics concepts throughout the unit.

Topics Included in these DNA, RNA, and Protein Synthesis Activities

This resource includes 35 warm up and bell ringer activities that gradually increase in complexity as students move through the unit.

DNA Structure and Replication

• early DNA experiments
• DNA structure and nucleotides
• nitrogen base pairing rules
• DNA replication
• proofreading and DNA repair
• interpreting the genetic code

RNA and Transcription

• differences between DNA and RNA
