The video tutorial demonstrates an experiment to measure humidity and temperature changes in wet and dry soil conditions using heat packs. Humidity sensors are placed in bottles on both soil types, and readings are taken every two minutes. The experiment tracks changes over eight minutes, providing insights into how soil moisture levels affect temperature and humidity.

What types of soil were used in the experiment?

• Silty and chalky soil

• Loamy and peaty soil

• Clay and sandy soil

• Wet and dry soil

Where were the heat packs placed in the experiment setup?

• On top of the soil

• Underneath the soil

• Beside the soil

• Mixed within the soil
