NGSS and Feedback Loops

Probably one of the strangest of all the Next Generation Science Standards is  HS-LS1-3 :  Plan and conduct an investigation

High School Students Doing Field Biology

If you are fortunate enough to teach near a university, there is a very good chance that programs at the

HIV Coloring

HIV coloring worksheet uses a model to understand viral transmission.  Students identify and color the major structures related to HIV

What Does NGSS Say About Cells?

The cell is a staple of any biology course, usually the chapter comes just after an introductory chapter on the

Are You Still Teaching Taxonomy?

If you are using an older biology book, chances are, the chapters are organized by kingdoms, phyla, and then orders.

Why I Teach Pathology in Biology

When you examine the AP Biology Course Description, there is no mention of pathology (the study of diseases) in the list

Precision Versus Accuracy

I was in the market for a new digital scale, mainly for the osmosis experiment where students must weigh dialysis

Teaching Evolution Using Animal Models

Most evolution units start with a history of evolutionary thought, where scientists of the past, like Darwin, Linnaeus, Larmarke, and


left_logo1Biology is the study of life and living organisms, from the smallest bacteria to giant sequoias.    Biologists use observation and experimentation to gain an understanding about the natural world.  Branches of biology include anatomy, biotechnology, botany, cell biology, ecology, genetics, medicine, microbiology, molecular biology, and zoology.   Many people entering the field of biology become specialized in a particular area.

As a course, biology encompasses four main themes:

1.  The process of evolution drives the diversity and unity of life
2.  Biological systems utilize free energy to grow, reproduce, and  maintain life functions
3.  Living systems store and transmit information essential to life processes
4.  Biological systems interact with each other, and those interactions possess complex properties.

The Biology Corner is a resource site for biology and science teachers and students.  It contains a variety of lessons, quizzes, labs, web quests, and information on science topics for all levels, including introductory life science and advanced placement biology.    You can find lessons related to biology topics in the links  listed under “topics” on the sidebar as well as specific curriculum for biology classes taught in high school.

The top menu contain links to classes for students currently enrolled.  Teachers may find the resources on those pages useful for designing their own curriculum.   All work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.   Teachers are free to modify lessons and worksheets to suit their classroom needs.

This site also contains resources to align a biology curriculum to the Next Generation Science Standards and prepare students for standardized tests.    Resources have been compiled and can be adjusted for any class or age group; teachers are free to modify any of the lessons or worksheets on this site.   Browse the “Worksheets by Topic” menu to find lessons specific for your class and curriculum.
