Plant seeds.

This is a fun activity that the kids can be part of every day! Take an old egg carton or old pots and some potting soil and help the kids place grass seed or other seeds you have available in the soil. Read the growing instructions carefully and tell the kids that it can be their job to water them when they need to be watered. If you plant grass, they can help cut it with scissors when it gets too long. If it's flowers, they can wait in anticipation for them to bloom.
