Make a tower out of marshmallows and toothpicks.
This is an Engineering challenge. Engineering is all about trying to figure out how to build something to the specifications and creative problem-solving. Our specification is that we need to build a tower using only toothpicks and marshmallows.
We had a look at some photos of some marshmallow and toothpick towers to get some ideas. We discussed the shapes we could build e.g. circle, square, triangle, hexagon and whether they would be strong. We also had some longer toothpicks available to us if we thought they would help support our towers. We all got a container of toothpicks and marshmallows. Then we were off to experiment and construct.
Of course, the most important instruction was not to eat the marshmallows until we had built our tower and taken a photo of it on Seesaw. At the end, we could deconstruct (this is the opposite of construct) our tower and finally eat those delicious marshmallows.
Perseverance became a keyword. Our towers did not always work the first time. But persevering, making adjustments to our design and asking a buddy to help us all were successful strategies.
Check out those cross supports in Stacys design
Daniel and Stacy found they needed cross supports to make their square shapes stronger. They used the longer toothpicks to make this cross supports.
Wow Hope what a great tower
Hope found that working with smaller shapes made her tower stronger.
Hope is looking pretty pleased with her tower
Maxwell had a clever plan to build a flat cube of toothpicks and then make it into a three-dimensional shape. He persevered and used a buddy for another set of hands.
Finally, Maxwells design has worked time to record on Seesaw
Macey worked with the triangle shape to build her tower.
Macey found using triangle shapes worked well
Maddox and Hunter decided working together on one tower was more effective than working on their own.

It was difficult and my tower kept falling over. Eden
My first tower was tricky so I pulled it apart and started again. Emma D
I found using the long toothpicks made my tower more stable. Daniel
I found it hard to make my tower balance. The best bit was putting my tower on Seesaw. Lachlan
Lachlan had the idea of side supports at each corner
I made a ninja tower. Liam
The best bit about building towers was that you got to eat the marshmallows at the end. Arkayzhia
I liked eating the marshmallows. Maxwell
A lot of thinking is going on here
Concentration is the name of the game
