Analyzing the Role of Vegetation in Urban Heat Islands
This project investigates how vegetation influences temperature in urban heat islands. By comparing areas with varying plant cover, students can assess the cooling effects of vegetation.
This project focuses on testing different minerals' hardness using the Mohs scale. Students learn to identify minerals based on their scratch resistance and gain insight into geology.

If I test various minerals against the Mohs hardness scale, then I will be able to classify them based on their scratch resistance.
