Please don't feel that you need to go out and purchase anything to do these activities, use whatever you have!
Materials:
Mini Marshmallows & Toothpicks or Pretzels
(If you don't have mini marshmallows you can use another candy that you have at home!)
Materials:
At the top of each cup punch two holes on opposite sides. String the yarn through and attach to the hanger. Place different objects in the cups to see which one is heavier. Now using legos have your kids estimate, "How many Legos does this toy car weigh?" "How many Legos does this Shopkin weigh?
You can use whatever items you have at home! :)
