We also had another design challenge! We had 40 minutes to build a car that could travel the longest distance with an array of supplies. Here is our design! Now, it looks like it didn't go far, but it came in 3rd! And had we had 10 more minutes and a redesign time, we would have won! We knew exactly what to fix. What did I learn from this? I need to give my students more time....sometimes! :)
