1) The experiment tested how radiation from a heat lamp affected the temperature of bare soil and grass-covered soil at different depths over one hour. 2) It found that heat was transferred faster in bare soil, with the bare soil 28.3°C at 24mm depth and 27.3°C at 65mm, while grass-covered soil was 26.9°C at 24mm and 25.3°C at 65mm after one hour. 3) The grass acted as an insulating buffer, slowing the rate of temperature increase and reducing temperatures compared to the bare soil.
