The purpose of this learning experience is to engage 3rd-grade students in understanding how physical activity, like biking, impacts the human body through hands-on investigation and data analysis. By acting as young scientists, students explore the cardiovascular and respiratory systems, fostering critical thinking and problem-solving skills. This project emphasizes collaboration, effective communication, and real-world application, encouraging students to make connections between exercise and overall health.

Students will understand the cause and effect relationship between physical activity and body systems, specifically focusing on the cardiovascular and respiratory systems. They will develop skills in data collection and analysis by measuring heart rate changes before and after exercise. Students will create and present interactive models to demonstrate their understanding of how exercise impacts the heart, lungs, and muscles. They will practice effective communication by sharing their findings with peers and community members during the 'Health and Science Fair'.

Students will create interactive models of the heart, lungs, and muscles to demonstrate their function during exercise. They will also develop presentations or posters showcasing their data collection and analysis of heart rate changes. These products will be featured at the 'Heart and Wheels Festival' and 'Health and Science Fair,' allowing students to share their findings with peers and the community.

Kick off the project with a 'Science Spin-Off' event where students take turns biking on stationary bikes while classmates use stethoscopes and timers to monitor and record heart rates. This active entry event will spark curiosity and excitement as students begin to explore how their bodies respond to exercise. Engage students in a brief discussion afterward to share initial observations and questions about the changes they noticed in their heart rates.

Organize a 'Heart and Wheels Festival' where students present their interactive models of the heart, lungs, and muscles, demonstrating their function during exercise. Set up stations with data displays showing heart rate changes and other findings from their biking experiments. Invite families, community members, and the P.E. teacher to participate in a community biking event, allowing students to explain their projects and findings.
