Plant a Garden
Save some individual yogurt containers and buy some seed packets for quick growing flowers. Zinnias, marigolds and cosmos have always sprouted within a week for us. Have the children scoop some potting soil into the yogurt container and add a few seeds. Then they can cover it with more soil and water. This is a great activity that teaches children responsibility as they care for their flowers each day. When the flowers grow larger you can transfer them to a larger pot.
I can't think of a better spring activity. We got all the supplies at the dollar store. You will need some Styrofoam pieces and plastic flowers. Have your children arrange the flowers in the Styrofoam. This really works those hand muscles and they are just delighted at their beautiful creations. I added some cups that the kids used as vases.
Enjoy your time with the kids!
