This 14-minute video lesson provides an overview of B cells (B lymphocytes) and how they are activated and produce antibodies. [Biology playlist: Lesson 53 of 71].

This 11-minute video lesson provides a review of B cells, CD4+ T cells and CD8+ T cells. [Biology playlist: Lesson 57 of 71].

Students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the color change of the indicator. They review the concepts of pH and respiration and extend their knowledge to measuring the effectiveness of bioremediation in the environment.

All living beings are made up of cells. Some of them are made up of only one cell and others have many cells. Also in: Dutch | French | Hungarian | Spanish

This is a remix of the Exploratorium Teacher Institute's Agar Cell Diffusion resource. It offers an alternate recipe for the cell blocks using plain gelatin instead of agarose gel.

In this unit, students will be given a chance to study and view different types of cells, compare and contrast the features of the major cell types, learn about the function of specialization and differentiation in multicellular organisms, and review/learn the major organelles that will become the foundation of later units.This module was developed by Liz Ashby as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.

In this lesson, students learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. And, students are introduced to the process of bioremediation and several examples of how bioremediation is used during the cleanup of environmental contaminants.

In this lesson, students continue their education on cells in the human body. They discuss stem cells and how engineers are involved in the research of stem cell behavior. They learn about possible applications of stem cell research and associated technologies, such as fluorescent dyes for tracking the replication of specific cells.

The lesson is designed for fourth grade students using scientific investigation to identify and compare the basic parts of a plant and animal cells. This activity consists of several steps over a period of several days. It includes student use of microscopes for observations and journals to collect data to identify and classify the basic parts of plant and animal cells. The assessment has an individual component and uses student work.

The fluid mosaic model describes the cell membrane as a tapestry of several types of molecules (phospholipids, cholesterols, and proteins) that are constantly moving. This movement helps the cell membrane maintain its role as a barrier between the inside and outside of the cell environments.

Fundamentals of Biology focuses on the basic principles of biochemistry, molecular biology, genetics, and recombinant DNA. These principles are necessary to understanding the basic mechanisms of life and anchor the biological knowledge that is required to understand many of the challenges in everyday life, from human health and disease to loss of biodiversity and environmental quality.

Express yourself through your genes! See if you can generate and collect three types of protein, then move on to explore the factors that affect protein synthesis in a cell.

Build a gene network! The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Explore the effects of mutations within the lac operon by adding or removing genes from the DNA.

A simple assessment or question bank focused on helping students differentiate between the subtleties and functions of various cell types. These questions can be used in a variety of ways for a life science or biology classroom, e.g. as an assessment, a pre-test, or incorporated into a group activity or game.

This activity is a lab investigation is which students will design and conduct an experiment related to movement of materials through a cell membrane. Modified from a lab I received from a fellow teacher, Jeanne M. Reed.
