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.

A Compare and Contrast Graphic Organizer


With the increasing amount of information that our students are expected to learn and master, it is more important than ever to provide them with the tools they need to organize and study difficult concepts.

This free graphic organizer can help your students learn to delve deeper into the content to search for similarities and differences between two topics or concepts.

Click image for free download.

This can be used in all subject areas and in grades 4 and up.  My students even admit that this technique has improved the way they view the content that we cover each day.  The graphic organizer can be used to compare and contrast any two topics or concepts.  I have used this organizer to have my students compare and contrast:
  • Photosynthesis to cellular respiration
  • Mitosis to meiosis
  • Protostomes to deuterostomes
  • Vascular plants to nonvascular plants
  • Systems of the body
  • DNA to RNA


The printable version is perfect for traditional classroom settings, and the paperless, digital Google Apps version is perfect for distance learning and 1:1 classrooms.

You can download this free graphic organizer by clicking on any of the above pictures, or on this link:


Enjoy!  ...And have fun teaching!
