Breathe, baby!

While studying the respiratory system, we did an engineering challenge: Can you make a pair of working lungs from 2 straws and plastic bags?

Yes, indeed! The Dragons are always up for a challenge! Everyone accomplished this task in their own way, but all were able to get the bags to fill with air through the straws. Most modeled the straws into a trachea and bronchi. We attached the finished product to our body models -- see these in a later post.
