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:
- Breaths per minute (at rest and after exercise)
- Pulse
- Number of jumping jacks in 30 seconds
- Lung capacity of each student
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.
