Lesson 4

Taking the Plunge: Designing Submersibles

Designing a Submersible / Grade 5 / Lawrence, MA

The EIE Curriculum

EiE- Taking the Plunge: Designing Submersibles Lesson 4

Students apply their knowledge of floating and sinking and ocean engineering as they imagine, plan, create, test, and improve their own submersible.

Reflection Questions

How do George’s introductions serve to connect today’s Lesson 4 activities with what the students have already done?

George’s introductions remind students of the context and the criteria of the challenge they have been working on.

  • On the first day, George gets all his students on the same page by reviewing the basic questions on the “Ask” handout from Lesson 4. The handout reminds students that the submersible they design should float, should be as a small as possible, and should have enough buoyancy to lift items from the floor of the basin. (0:50)
  • On Day 2, George reviews the term “criteria” and reminds students of the specific criteria that their submersible needs to meet: it must be buoyant and it must include lights and a battery. (3:43)

How do you see George’s students practicing math as they evaluate their designs?

George’s students evaluate their designs using the numeric scoring system provided in the guide.

  • Students must score their designs on three different variables (volume, instruments package pick-up score). The total score on all variables determines how well the design performs. (6:30–6:50)
  • As students improve their designs, they think about which vials they are switching out and recalculate their volume and instrument scores to increase their overall scores. (8:45)
