The Spaghetti Noodle Tower Challenge

We started our engineering unit last week.  We've learned that engineers build things to solve problems.  They use creative and innovative ideas.  We've also learned there are different types of engineers.  Some may create new things, some take things apart to see how they work, and some study why things don't work. 

Our first task we took on as engineers was to make a tower out of spaghetti noodles and marshmallows.  Each small group was given a box with 30 noodles and 30 marshmallows.  Before the groups got started we discussed the importance of team work and using words of encouragement with each other.  I let the class know that it's okay to feel frustrated when your ideas don't work the first time and asked them how they would handle it.  They all agreed that as engineers they needed to just try a new idea if their first idea didn't work.  They students were so excited to get to work! 

After the first work session, it's not uncommon for groups to end up with snapped noodles and gooey marshmallows.  The class soon learned that marshmallows and noodles are not stable building materials, but they did not give up!  We talked as a class about what was working and not working.  Groups suggested ideas for other groups to try such as doubling up noodles to make them stronger.  In their next work session they were given 10 more noodles and 10 more marshmallows.  In their third and final work session, they were given an additional 10 noodles and 10 marshmallows. 

I loved seeing their teamwork and the support they gave each other.  I heard conversations such as, "That's a great idea!  Let's try that!"

The final step was to measure each tower.  Although it's exciting to build the tallest tower, I told the class that they all accomplished their goal by having a standing tower!  I was so proud of the cooperation and teamwork they put into this project.  Way to go 2nd graders!
