I am really enjoying our science play at the moment.
Learning through action. Most definitely without realising it.
Mostly my boys experiment with all sorts of fun ingredients
& materials themselves, but now and again I'll remember a project
I loved when I was young - then we'll all join in together.
Balloon Rockets were one such project.
Did you do this when you were young?
How to make a Balloon Rocket
Attach a length (about 2-4 metres) of string at one end, to a chair or door handle.
We chose a book case, as I wanted to surprise my boys with the rocket travelling upwards... defying gravity!
Blow up a balloon.
Attach a peg (or hold) the neck so as the air stays inside,
while you sticky tape it to a straw.
Thread the straw onto the length of string.
(Make sure the neck of the balloon is facing the start point
and the inflated part of the balloon facing the end point)
Hold the string taught and then let go of the balloon end
(or remove the peg)!
We've seen in action the principle:
every action has an equal and opposite reaction.
(Escaping air propels the balloon in the opposite direction)
We have also learned the effects of Air pressure, Thrust, Force and Acceleration.
All through play and experimentation.
And all we did, was make balloon rockets.
