During our recycling unit, we reused cans to plant marigolds. It was a time for the kids to get messy and learn about planting.
I told the kids the only rule was for them to get messy, so they had to scoop out the dirt!
Give them a few seeds. This is also a great time to discuss how different seeds look.
Time to get dirty! Have them scoop dirt with their hands to cover the seeds.
Make sure to water them good!
