Moving objects are often pushed or pulled by hands, feet or other extensions of our bodies. We’ve used ramps and slides to speed things up and bumpy surfaces to slow things down.
Now, try making things move without touching them!
Show your kiddos a small, lightweight ball (the dollar store usually has ping pong balls in packs!) and talk about how they could get it to move ... without touching it! See if they can come up with pushing the ball with their own breath :)
You will need a straw - maybe from a sippy cup or water bottle, or maybe you have disposable straws tucked away in a drawer. Then, get out some play dough or blocks (or both) to have some fun moving the ball without touching it. :)
Roll out some skinny play dough “snakes” and encourage your friends to use them to design a maze for the ball the roll through. See what designs they can come up with! Sometimes a side-by-side play example will help to get their creative juices going.
See what directions they can make the ball go in, and what they learn from this ... Do you have to blow softly? Is it better if you blow harder? Where does your straw need to be? Encourage them to think outside the box ... what else could you use? Would a paper towel tube work? Which works better? How else can you make air move?
We are scientists! Have fun!
