MARSHMALLOW & TOOTHPICK CHALLENGE
After observing the children over the last week challenging themselves to build the tallest tower out of the straw connectors, we put out toothpicks and marshmallows to scale the challenge down in size. The children worked in small groups and independently to create different shaped towers. Nicholas and Tom worked on making “tent” shaped blocks and connected them together. Daniel made cubes from his marshmallows and stacked them on top of one another. Lillianne kept building upwards and measured her structure at 30 cm. The children kept building and measuring but what stuck out the most through this experience was a theory that Andrew had as he was building…
“Tringles are stronger than squares” Andrew said as he started putting some pieces together. “Math taught me that.” When asked what kinds of things he could think of that are triangle and strong, he replied “pyramids”.
I challenged his thinking….”Why aren’t our buildings triangle then?”
“The support beams in the walls are triangle” Tom replied quickly.
How can we support and test out this theory with the children without giving them the answer?
A parent said we should test this out using eggs and heavy blocks...we are ready to get messy!
