Hello! This is Kim from The Learning Hypothesis. I have a cell freebie for you.
Cells are the basic unit of life.
That is one of my least favorite definitions of a scientific term. What is a unit of life? What does that really mean? I have a graduate degree and struggle to make sense of that so I can’t imagine how our middle school and high school students feel.
That single word, cells, makes a large component of any life science course. Cells are something that many people feel are just a simple topic, but in reality, it can be tough for our students to understand the similarities and differences between various cells. After over a decade in the classroom, one of the more common misconceptions I’ve seen is about the variety of cells. You could also use a project based learning unit on cells.
Why should we change how we approach cells?
I’ve taught human anatomy and physiology a long time and the variety of cells in the human body that look and behave differently from the generic animal cell most students are familiar with can create an enormous obstacle for students to overcome.
I suggest a different approach to teaching cells that focuses on the idea of commonalities rather than a generic one size fits all model.
You can find out more about how I approach an introduction to cells and grab my cell freebie to help you get started by clicking the image below.
These include both a plant vs. animal AND a eukaryote vs. prokaryote worksheet with answer key included.
All the best,
