We have been learning about the water cycle with a focus on evaporation, condensation and precipitation. To understand more about this process we decided to make a terrarium. This way we could observe first hand how the water cycle works. Similar to the way water evaporates and rises into the atmosphere before condensing and falling as precipitation, in our terrarium, the moisture from the soil evaporates and rises before condensing on the top of our container. It then falls (like rain) to provide moisture to the grass in our terrarium.
It was amazing to witness the water cycle happening right in front of us. Not only did we learn more about evaporation, condensation and precipitation, we also learnt about transpiration. Transpiration occurs when the grass soaks up the water in its roots, then ‘breathes’ with respiration, releasing the water (and oxygen) into the air which then condenses on the container and rains. Amazing stuff!!
