Can you build a slide with two tracks?

Last week's problem solving challenge was to build a slide. We added several new challenges as we went. First they were told to simply build a slide with a few sheets of paper, tape, and scissors. 

Next, they were told to extend their slides longer. 

Third, they were told to build two tracks so the pompoms would fall down either side. 

Short slide

Longer slide!

This group worked through several challenges such as the pompom falling out of the tunnel before it went down the final track. They persevered and were successful! Notice the flap added under the first tunnel to ensure the pompom stayed in the track! 

This group went with an open slide and I wasn't sure if the pompom would stay on the slide or how they would build a second track...but they knew what to do! Never underestimate an invested learner!

Look at this intricate design! They worked hard the entire time and their final slide was amazing.

This team attempted several variations and decided this was their favorite!

This group had a plan the entire time and knew exactly what they wanted it to look like in the end. They made several adjustments and the pompom went through the slides without getting stuck!

When asked what the most challenging part was, several said: "making sure the pompom went down either side of the track". 

We love remembering what we learned from Rosie Revere Engineer, a first flop failure leads to success!
