Human Body | Project Based Learning
Students work in small teams to design and present a model or poster showing how major human body systems work together to keep the body functioning. The lesson emphasizes collaboration, problem-solving, and evidence-based explanation.
| Term | Definition |
|---|---|
| organ system | A group of organs that work together to perform a major body function. |
| circulatory system | The body system that moves blood, oxygen, and nutrients throughout the body. |
| respiratory system | The body system that brings oxygen into the body and removes carbon dioxide. |
| digestive system | The body system that breaks down food into nutrients the body can use. |
| nervous system | The body system that sends messages and controls body responses. |
| interaction | The way two or more systems work together to do a job. |
Show a prompt such as, 'How does your body get oxygen to your muscles when you run?' Ask students to think, then turn and talk.
Share prior knowledge, name systems they think are involved, and listen to partners.
Assign teams and distribute task directions. Explain that each team will create a poster or model showing at least two body systems and how they work together.
Choose systems, sketch a plan, and decide how to show the connection between systems.
Circulate, ask probing questions, and support accurate use of vocabulary. Check that each team includes labels, functions, and interactions.
Create the product, label body systems, and prepare a brief explanation of how the systems interact.
Invite a few teams to present one key connection. Use a timer to keep presentations brief.
Present their work, explain system relationships, and ask or answer questions.
Prompt students to write one sentence: 'Two body systems work together when ______ because ______.'
Write an individual response and submit it as an exit check.
Reinforce that body systems do not work alone; they depend on one another to maintain life. Highlight one strong example from student work and connect the lesson to everyday activities like breathing, eating, and movement.
Students will be assessed using a simple rubric for accuracy of science content, clarity of explanation, use of vocabulary, teamwork, and completeness of the model or poster. The exit response will serve as an individual assessment of understanding.
Choose one daily activity, such as running, eating, or sleeping, and write 5-6 sentences explaining which body systems are involved and how they work together.
