Creating a Homemade Weather Station

Students will construct a weather station using basic materials. The station will include a thermometer, hygrometer, barometer, and anemometer. This hands-on activity will help them gain practical insights into the measurement of meteorological variables.

1. Divide the class into groups of 4 to 5 students.

2. Distribute the necessary materials: plastic bottles, alcohol, water, balloons, straws, tape, scissors, plastic cups, cardboard, and more.

3. Each group should follow the instructions to construct the meteorological instruments:

4. Thermometer: Fill a plastic bottle with a mixture of water and alcohol, insert a straw through a balloon placed at the mouth of the bottle, and tape it up properly.

5. Barometer: Fill a plastic cup halfway with water, place another upside-down cup inside the first one, and observe the changes in the water level.

6. Hygrometer: Use a strip of cardboard and a piece of human hair to measure air humidity, as the hair expands and contracts with changes in humidity levels.

7. Anemometer: Construct one with four plastic cups mounted on a rotating base to gauge wind speed.

8. After construction, each group should present their instruments to the class, explaining how they function and the variables they measure.

Allow students to practically experience how meteorological instruments work and understand the methodology behind climatic variable measurements.

**Durasi: 40 - 45 minutes
