    Thanks for the wonderful suggestions for science to do with the kids at home.
    Our family came across this challenge – to build a “Rube Goldberg” inspired machine or wacky contraption with 10 to 20 steps with the goal to drop a bar of soap into someone’s hand at the end. The contest is open to all and runs until May 31st. We’ve started working on our wacky contraption. It’s been a lot harder than we anticipated and became all-consuming over the Easter long weekend, but fun to build. It teaches a lot about energy transfer, lever action, and what you can build with a supply of rubber bands, twine, recyclable materials, golf balls, bamboo skewers, chop sticks, etc…you name it! Details are here:

    And here (Rube Goldberg’s granddaughter explaining the rules):
