STEM Challenge for Kids: Create a pinball like marble maze game using paper plates and other basic craft materials. Fun design and building challenge! ~ Added idea- roll marbles in paint and then place in maze.
Take a 2 liter soda bottle, poke holes in it. Attach to a garden hose. Toss over a tree branch and let hang for a kids water sprinkler. I might actually make this! You can loop it over a tree branch and let kids bat it around for more watery fun!
PVC Sprinkler Water Toy - how smart is this? 10 bucks worth of materials from the hardware store will bring lots of joy this summer. :) TWIST use a couple of pipes and plastic streamers as well, call it a "car wash" and ride bikes through it.
