4SP have created their own terrariums to investigate the water cycle. We have used tropical plants, plastic bottles and soil to replicate the water cycle. Here are some pictures:
We are observing the terrarium over time to see what changes will happen.
We predict that the water would evaporate and condense on the side of the bottle.
We predict that the temperature inside the terrariums will be higher than room temperature.
We predict that plants would grow inside the terrariums.
Already we have noticed condensation inside the bottles, indicating the water is evaporating. We have put thermometers inside the terrariums to see if the temperature differs and we have started to measure the plants.
