An eight-unit electronic textbook provides a guide to AP® Biology. Each of the 28 chapters include an introduction, multiple lessons, a summary, review questions, and test prep questions. Teachers see how each lesson connects to a big...

Blood passes through the kidneys about 300 times a day. Show your class how the kidney and bladder work together to filter blood in the excretory system. This 19th video in the series explores how the circulatory and respiratory systems...

She had a terribly busy day converting oxygen into carbon dioxide; now she just needs a moment to breathe. In the activity, scholars review the function of the respiratory system and discuss bioengineering's role in medicine/health and...

How does something remain the same in order to change? The video discusses homeostatic evolution from both the continuity and changing perspectives. An analysis of the excretory system in flatworms, earthworms, and vertebrates shows...

With a partner, youngsters measure their pulse and breathing rates, both at rest and after running in place for a minute. While this activity is not novel, the lesson plan includes a large-scale classroom graphing activity and other...

The ins and outs of breathing are explained in this fresh film. Simple and straightforward narration accompanies colorful animation to show how breathing is controlled and how it can be altered. This would not only be useful during a...

Immerse biology learners in circulation and gas exchange for both simple organisms and higher animals. Six pages of short-answer questions and labelling of the human respiratory system are included. This assignment was written for an...

An incredible series of lessons on the human body is here for you! Young scientists explore various websites, construct a skeleton using macaroni, compare/contrast a frog skeleton to a human skeleton, label the main parts of the human...

Explore structures within the realm of gas exchange in terrestrial and aquatic life.  The excellent, labelled diagrams and clear descriptions help your students view the different structures and adaptations that have developed. The 29...

Inhale, exhale. Inhale, exhale. Ensuring that patients breathe and get enough oxygen is the job of the respiratory care therapist. Find out what is involved in this medical career with a short video that shows some of the many aspects of...

Two activities teach middle schoolers about asthma and how it can affect people's lives. After reading a series of articles and watching two videos that provide background information about asthma, pupils design an interactive game that...

Curriculum resources can be expensive—but not this one. An online textbook offers informational text for a complete high school Biology course. Topics include energy flow, body system, genetics, and evolution.

The body is one big life-sized puzzle! A hands-on lesson builds on the idea and has individuals create life-size models of the body including all important organs of the digestive, circulatory, and respiratory systems. After building...

Teamwork makes the dream work! A well-designed lesson helps learners discover how the circulatory and respiratory systems team up to keep their bodies alive. The lesson includes a diagram of the major connections between the lungs and...

Sometimes a little pressure isn't a bad thing! A collaborative lesson uses models to demonstrate how air pressure inflates and deflates the lungs. Participants use everyday materials to create models of the chest cavity to simulate how a...

Pupils know they need to breathe to live, but the details may not be too clear. A thorough lesson plan introduces them to the components of the respiratory system using a set of cards with pictures and descriptions.

A little bit of this and a little bit of that. The final lesson of the 21-part unit assesses learners on each animal and plant system. The test covers the basics of each system and focuses on key vocabulary from the unit.

How much do classes know about the transport systems in animals and plants? Find out with a ready-made pre-assessment! The assessment begins by asking individuals to recall related vocabulary and then progresses to questions about...

Don't fall victim to The Silent Killer! Expose your class (not literally) to carbon monoxide through an informative video from Reactions, a playlist from the American Chemical Society. Content includes carbon monoxide's structure, its...

Physics ... saving lives, one equation at a time! Learners discover the sad truth about premature babies and respiratory distress syndrome, which claimed millions of lives before scientists could understand its cause. Physics, and the...
