Human Body | Small Group
Students explore how the human body works as a system and connect body needs and functions to Earth science ideas such as air, water, soil, rocks, and the Sun’s energy. In small groups, students investigate how body parts help people survive and how Earth resources support life.
| Term | Definition |
|---|---|
| body system | A group of body parts that work together to do a job. |
| organ | A body part that has a special job, like the heart or lungs. |
| resource | Something from Earth that people need, like water, air, or soil. |
| survive | To stay alive. |
| energy | The power needed to do work or be active. |
Show a picture of a child outdoors. Ask: What does this person need to stay alive and healthy? Record ideas on chart paper.
Think-pair-share and name needs such as air, water, food, shelter, and movement.
Explain that the human body is a system. Model with simple examples: lungs help us breathe air, the heart pumps blood, the stomach helps break down food. Connect each need to Earth: air from the atmosphere, water from rivers/rain, food from plants and animals, shelter from materials found on Earth.
Listen, repeat key vocabulary, and point to body parts on a diagram when named.
Give each group mixed picture cards of body parts and Earth resources. Model sorting one pair together, then guide groups to match body part cards with the resource or need that helps it work. Circulate and prompt with questions.
Work together to sort and justify matches using sentence frames such as 'The lungs need air because...'.
Pose challenge questions: What if there were no clean water? What if the air were dirty? What if people could not get food? Record responses in a two-column chart: resource and effect on the body.
Discuss in groups, then share one idea with the class about how missing resources affect health and survival.
Ask students to create a simple map or organizer with a person in the center and arrows to air, water, food, and shelter. Encourage them to add body parts and a short explanation for each connection.
Draw and label the organizer, then explain their thinking to a partner or teacher.
Invite groups to present one strong connection. Review vocabulary and correct misunderstandings.
Present, listen to others, and add one new idea to their recording sheet.
Bring the class together to complete the sentence: 'The human body needs Earth resources because ______.' Highlight that living things depend on both body systems and Earth’s natural resources.
