MAKING THINGS MOVE
How many ways can we use the straws to make the blocks move?
A big ‘push’ like a flick makes the blocks shoot across
the floor really fast!
I can makea ‘push’ by
blowing through the straw.
Lifting the blocks up is a ‘pull’.
What about making another ‘pull’ by sucking the block
up with the straw?
I could try making a tower with the blocks then throwing the
straws at it to knockit down. That would be
another ‘push’.
I can ‘push’ the blocks across the floor and I can
‘pull’ them up off the floor with my straw
chopsticks.
