Sizing Cells

This series of handouts and images asks young scientists to read short informational paragraphs, answer identification questions, and color and label diagrams of animal and plant cells. This is a complete resource that could be given as...

Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...

Make sure your scientists are reporting their work effectively by providing them with a reference for their lab reports. The first few pages of this resource detail each element of a lab report, and the last few pages provide an example...

Can your class solve the Mystery of the Crooked Cell? Junior geneticists collaborate to learn about sickle cell anemia in a fascinating lesson plan. The included materials help them to examine the genetic factors behind the disease...

Adult humans are made of around 40 trillion cells that can't be seen these without some really powerful microscopes! Learners tour both prokaryotic and eukaryotic cells, learning how their structures are similar and different, and...

Why are Henrietta Lacks' cells immortal? The answer is that no one really knows. But much has been learned because they are. Check out this video that introduces some of these remarkable discoveries.

Get up close and personal with human cells with this lab worksheet. Learners use a microscope to examine their own cheek cells, drawing diagrams of the cells and identifying the parts when they have focused in on a visible specimen....

It is hard to believe a 300-foot-tall Redwood tree began as a single cell hundreds of years ago. How did it grow so large? Observe how different kinds of cells (bacteria, sex cells, and eukaryotic cells) reproduce or make more cells...

Explore the structure of cell membranes including cholesterol, glycolipids, glycoproteins, phospholipids, and proteins. The video shows and discusses the fluid mosaic model as well as how cell walls differ from cell membranes. 

Cell membranes contain many contradictions; for example, they are both oily and strong. The video explains the parts of a cell membrane, the function of each part, and discusses the contradictions. It highlights what happens when...
