This post is linked to two series A-Z science for Questioning and out potato fun.
So the question: which size potato rolls down the slide the fastest??
My son predicted that the big one would but wasn't sure why.
Dylan had a target to describe objects in terms of size . So he chose a big, small and medium sized potato.
This was an unplanned activity and we didn't record results but I timed the roll and he observed what happened.
The medium and big potato were close in size and the way he let them go meant that they took in terms being the fastest.
