Wesley has a wheelbarrow in the sandbox, and he is shoveling sand into it. When it tips over, he tries to right it, and expresses frustration when it keeps on tipping over. Mark comes over, and wonders if Stella, nearby, can help solve the problem. She is game! Her immediate reaction is to lean various items around it: a shovel, a half-pipe, and a bucket.
When Stella crams a ball under the side
that has been falling over, it does the trick!
Wesley notes this strategy,
and the next time it falls over,
he retrieves a bucket and
puts it underneath – success!


But the next problem is that the wheelbarrow won’t roll – it is stuck in the sand. No worries! He grabs a half-pipe and puts it under the wheel. As elegant a solution as this is, he still can’t get the wheelbarrow to budge. He switches strategies, opting to transfer the sand into a wagon to get it out of the sandbox. At first he uses a shovel, but then becomes enamored of the cone as an intermediary device. At this point his interest wanes – but what an exploration!
