Watering plants
Watch the video and listen to the sound.
Get used to watering a houseplant. Make one of the plants at home 'your own'. Water the soil whenever it gets dry (usually about once a week, but you may need to water it more often in hot weather, less if it is in a cool place).
Put your plant in a saucer and add water to the top of the soil until water starts to fill the saucer.
Let the water drain out, throw away the surplus water in the saucer and put the plant back where it normally grows.
