Students read and complete a worksheet about the levels of organization of living things from cells to organ systems. They use a text book and the "Cells R Us" worksheet included to create a metaphor for each of the levels. They then...

Discover how the human body's digestive system works with a brain and stomach friendly activity. Scholars taste test a variety of foods to find out how they behave once in the mouth. Class members then play a game called Move That...

Students examine the body's major organ systems and how they function and influence each other. They examine how the human body moves when involved in sports.

What do your vital signs tell your doctor? An engaging hands-on lesson has your learners monitor their own lung capacity, blood pressure, and heart rate. They then connect the vital measures to the workings of the circulatory and...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Students examine and research the organs of the respiratory system. They participate in a vocabulary card matching game, create a graphic organizer, and participate in an experiment titled, Floating on Air.

Eighth graders investigate animal behavior by studying the lives of three female behavior scientists.  In this human organism lesson students do different activities that inquire and approach each females work. 

High schoolers identify the different parts of the circulatory system and their function. They work together to create their own model of the system and use it to determine the rate of blood flow. They answer questions related to their...

Fourth graders practice reading in the content areas (science) in order to explore the interdependence of the body systems. They answer written questions after reading.

Get to know the body's central nervous system through an engaging game of nervous system telephone. But this isn't your average game of telephone. Here, pupils must find a way to communicate a message to the brain without speaking....

Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

Young scholars research information about the human body. They read books and explore the Internet to gather information about the human body. Students create graphic representations and models of the body systems. Working in groups,...

Students identify and analyze that Global Interdependence and Internationalism have become major themes in human activity in the areas of population, environment, the world economy, and the United Nations. Students identify the...
