Barometric Pressure Sensor Experiment Kit

This educational experiment kit allows students to explore various topics such as altitude, weather, and atmospheric pressure changes using a barometric pressure sensor and an LCD display.

1. Measuring Air Pressure Changes by Altitude

By measuring the barometric pressure at different floors of a building (from the ground floor to higher levels), students can observe how the sensor readings change and experience the principle that air pressure decreases as altitude increases.

2. Measuring the Volume and Temperature of Air According to Pressure in a Vacuum Chamber

Through a vacuum experiment that artificially reduces air pressure, students can experience the concepts of gas laws in a hands-on way—such as Boyle’s Law (pressure and volume) and Charles’s Law (temperature and volume).

3. Predicting Weather Changes Based on Barometric Pressure Variations

This activity involves continuously recording barometric pressure data over the course of a day or several days and comparing it with actual weather changes. Students can observe that lower pressure often leads to rainy weather, while higher pressure is associated with clear skies, helping them naturally understand the principles of weather observation and prediction.

Through data table creation and graph analysis activities, students gain experience in scientifically interpreting sensor data.
