Students design a proportional model of blood out of red gelatin, a plastic bag, and rice. They study the components that make up blood and investigate what happens when the arteries in different scenerios. They work in pairs in order to...

Fifth graders review the components of blood and write four things they have learned. They view a videodisk related to blood components and create a batch of candy "blood" using terminology including platelets, red blood cells, white...

Fifth graders examine how a red blood cell travels throughout the body. Using a model, they recreate the flow of blood through the heart. They also label the lungs and the differece between the blood that enters the heart and the blood...

Students observe number sense by participating in an estimation activity. In this blood cells lesson, students identify the importance of blood cells in the human body and discuss how tiny they are. Students utilize paper dots as a...

How can the circulatory system compare to a city map? Pupils distinguish the "roadways" and "vehicles" of the cardiovascular system, compare the anatomy and function of veins and arteries, and review different types of blood cells with...

students research blood's components, and use their math skills to recreate a model of whole blood using commonly found food items.

Ninth graders study facts about human blood and what it is made of.  In this blood composition lesson students divide into groups and complete several activities. 

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

The New York Regents High School Examinations are comprehensive and include various question formats, including multiple choice and graph analysis. This particular version, the 2008 Living Environment exam, surveys a variety of topics....

The 2005 version of the Regents High School Examination in ecology is as comprehensive as previous years' exams. It consists of 40 multiple-choice questions on topics ranging from the structure of DNA to interactions within an ecosystem....

Students explore how our bodies fight infection. Using a microscope, they observe red blood cells, white blood cells and different bacteria under a microscope.

Seventh graders explain the role of white blood cells in fighting infections. In this life science lesson plan, 7th graders create flow charts showing the immune response process. They act out and play a game to simulate actions of the...

Fifth graders examine how a red blood cell travels throughout the body. Using a model, they follow the flow of blood throughout the entire body. They identify the functions of the lungs and discuss the difference of the blood entering...

Students examine T cells and the role they play in the immune system.  In this interactive lesson students work in groups to complete an online training and make a comic strip with what they learned. 

Twelfth graders investigate specialized structures in both plants and animals. They relate structure to function, as they determine why the specialization is necessary and useful to the living organisms involved. They use microscopes...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Students examine the cell coats (matrix) of chondrocytes and fibroblasts and observe these cells actively exclude particles which are released around them. They observe the function of the cell membrane as a gatekeeper as it prevents...

In this circulatory system worksheet, high schoolers review the organs that are involved with this body system, including their structure and function. Students explore the problems that can occur with the circulatory system. This...

Students examine the different parts of blood.  In this human blood lesson students work in groups and identify parts of blood and construct a model of human blood. 

Students examine inheritance of blood types.  In the chromosome lesson, students create a model of chromosome and predict the blood type of offspring.

Here is a lab that has teenage scientists examining samples of their own blood under a microscope. Learners carefully prepare slides, then make detailed observations and identifying different types of cells using a key. 

Students listen to story, The Magic School Bus: Inside Ralphie, take notes from story on how body fights germs, identify different functions of immune system, and use Kid Pix slide show to explain how body fights viruses and bacteria.

Students research the structure and function of the nervous system. They prepare a model or representation of neural transmission. Students create an infomercial about nerve cells.

Students explore the types of cells and their appropriate function. After observing a PowerPoint presentation, students draw diagrams of cells. Using a specified website, students identify parts of plant and animal cells. They answer...
