intro to human body systems

Grades k-2

In the basic lesson, students will be introduced to the concept of systems as it applies to the body using the “Hokey Pokey” song and comparing object systems to the human body system. Then using body part pictures, the students will group the parts using their own classifying choice and describe why they grouped the body parts the way they did. Using activity cubes, the students will identify what body parts are used for each activity presented on the cube. Using body part cubes, the students will identify the name and function of the body part.

The advanced lesson is an excellent way to teach students about the six human body systems. Each system has a separate activity-based lesson where the students will explore and learn the name of the major organs and function of each system.
