Submersibles

I was really impressed with our fifth graders last week when each class completed the last challenge that aligns with our submersibles unit.  Before entering into this challenge, they had to investigate and grapple with the idea of mass and volume in relation to sinking and floating. Some students even began to understand the concept of density.

Every team was able to complete the first challenge of creating a floating submersible with different density vials that served as the submersibles “instruments”.   Almost every team after that, was able to complete the challenge of retrieving three different packages from our “sea floor”.   In the end, I was impressed that most students were able to understand mass and volume in relation to sinking or floating.  These concepts can prove confusing for students.  Our fifth grade proved that when engaged and challenged they persevere and can learn complicated scientific understanding.

  1. This IS a challenging unit! I taught this one to teachers in Georgia and it took us the better part of the week to get it to work. Good for you! Love the application to life. Looking forward to my girls having your expertise!
