Fun idea: If you don't pick something up after one warning, this mom confiscates it and puts it in a "ransom box." The only way you can get it back is to draw a task from the envelope attached to the box lid. Her tasks are hilarious!
Creating your own rainstorm...this is so cool! All you need is a clear container, water, shaving cream, food coloring and droppers. Have kids make predictions by drawing what they see and think will happen.
