Engineering challenges 2nd grade - 1st challenge

For this challenge the students were given the problem of building a boat with limited materials that could float and hold 6 Lego people.  They worked through the Engineering Design Process to complete the challenge.  They could only use 5 straws, one piece of wax paper, and some tape.  They drew out their own ideas and then were put into teams to decide on a final idea.  Once they decided and all teammates agreed, they were able to get their supplies and start building!  The process required excellent negotiation skills, cooperation, and critical thinking/problem solving.  I am so proud of their results!  It was incredibly rewarding to watch them struggle through each step to get to the final float test.  Not all boats floated the first time and some needed to be improved.  They handled this like champs.  I believe that this type of tenacity will get them far in life.
