STEM STATION
Introduce biosensors with an emphasis on air quality sensors that monitor air quality on different localities. How they do the entire process and how they are linked with an application that indicates less polluted areas. How tis help public to take alternate route via travelling on road to make environment less polluted.

Respiratory System Activities to Test Lung Capacity

Students work in pairs to measure lung capacity. Using a balloon and string, each child breathes one breath as hard as they can into the balloon. The other child measures the circumference of the balloon using the string. The class discusses that the air in the balloon represents the amount of air that used to be in the students’ lungs. They discuss the differences in the lung capacity between the students and come up with various hypotheses on why lung capacity varies.

Respiratory System Activity to check relation between breathing per minute with heart rate with different physical activity.
In this activity, students observe breathing patterns at rest and after exercise. Students sit quietly for 30 seconds and reflect on their breathing. Students discuss their breathing rate and how they feel. Then the children get up and do jumping jacks for 30 seconds. Immediately after the jumping jacks, the students reflect on their breathing. Class discussion focuses on whether the children are breathing faster after exercise and why this is (the body needs to take in more oxygen).
Students take specific measurements and analyze the data. These measurements could include:
Have the students craft a hypothesis, choose what data they collect and have them analyze the data via graphs, equations and comparison of data points.
