Nothing is more relevant than the study of the human body. A series of 10 human body lessons begins with growth, ends with reproduction, and hits all the major systems in between. Each lesson provides opening and closing activities as...

Inhale, exhale, and rest easy when looking for a supportive tool for your activity on the respiratory system. Seven slides introduce the class to the function of the organs: lungs trachea, diaphragm, bronchial tubes, bronchioles, and...

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...

When you get to the heart of the matter, you learn a lot about an organism by studying its circulatory system! A perfect resource for a zoology or anatomy class, the simulation gives users a peek inside a variety of vertebrates to...

Learners study the relationship between the heart and circulation. In this circulatory system lesson, students read the "What Am I?" article about the heart and discuss. Learners draw a heart and lungs, discover how blood is pumped...

Fifth graders study how respiration and circulation are connected.  In this respiratory lesson plan students complete several activities to better understand heart rate and carbon dioxide in the body. 

Students study how lungs and a diaphragm work to make them breathe.  In this pollution lesson students build a lung model and learn three things they can do to protect themselves from the effects of fossil fuels. 

Although it was published in the year 2000, this chemistry assignment is ideal for practicing the application of Charles' law. There are seven real-world problems to solve, and plenty of space provided for doing so. Add this to your...

Students study the parts of the human respiratory system while examining the gas exchange that takes place in the lungs. They make a model lung. They look at how the respiratory system is affected by spaceflight.

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.

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

Fourth graders investigate the characteristics of each vertebrate group. They take notes in a science journal, and in small groups create a HyperStudio slideshow presentation to present information about a specific vertebrate group.

Students share ideas about how scientists know about dinosaurs, then read a news article about the recently found remains of a hadrosaur. In this dinosaur lesson plan, the teacher introduces the article with a class discussion and...

In this fluids, electrolytes, and acid-bas balance system study questions, students define 12 words associated with this system. They answer 12 short answer questions about the components of the acid-balance system.

Students study the respiratory system, the lungs and air.  In this respiratory lesson students describe technologies that engineers have found that improve the health of the respiratory system. 

Students study the function of lungs. In this lung function lesson plan, students complete an experiment using balloons to study the way lungs work. Students study a diagram of their lungs and make a hypothesis for their lung capacity...

Students study toxins. In this biology lesson plan, students identify toxins contained within household products and determine specific affects that toxins may have on the human body.

Students study the components and functions of the respiratory and circulatory systems. They take blood pressure using a stethoscope and investigate ways to maintain a healthy respiratory system.

In this circulatory system worksheet, students read a paragraph about the function of the different organs that make up the circulatory system. Then students complete 3 short answer questions.

Students investigate the harmful impact of global warming by reading news articles.  In this environmental care lesson, students analyze an article about the Kyoto Protocol and its goal of saving our environment.  Students...

In this body systems worksheet, students read information about the processes involved in the respiratory and urinary systems. Students then answer 1 short answer and 2 multiple choice questions.

For this human heart worksheet, learners read a short passage about the human heart and study a diagram. Students then fill in the blanks to complete the 8 questions about the human heart.

After studying DNA replication and the genetics of inheritance, this slide show is useful for explaining specific mutations that can happen and result in an illness. Sickle cell anemia, and cystic fibrosis are explained on a genetic...

Different types of teeth have different roles. Third graders study how molars, incisors, and canines function in a rabbit skull and a cat skull. After answering some questions about the teeth of herbivores and carnivores, kids...
