Planting lettuce

First my mum and dad bought me some seeds.It were celery and lettuce.The lettuce is mine and the celery is my little brothers'. I planted it with a help from my mum. First I have to empty the compost in a black tray. Then I have put a bit of water and later planted the seeds into the compost. It is my school project. I have to see and chart the grow. Let see how it grows together.
