With treatment and intentional planning, companies can prolong the life of a vessel, making it more cost effective (and producing less waste) for the company.Īfter this activity, students should be able to: Companies that rely on cargo ships to transport goods and materials do not want to spend a lot of money on a full-size ship without knowing how much is will hold and how well it will hold up to environmental elements. This is especially true when wanting to create (and duplicate) products on a larger scale. Often in their testing, engineers use models to test and improve new designs and materials.
With further research and intentional planning, engineers can design solutions to prevent corrosion to prolong the life of different metals and their applications. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Ĭorrosion has an adverse effect on many industries by lowering the shelf life of various metal products. At the end of the testing period, students reflect on their design and engineering choices as well as what they would change if they repeated the activity again. After the initial design and build, students set their ships to sea and then monitor their ship daily, collecting observations about their ship (e.g., floating vs. Students choose the design and shape of ship, the metal used to make the ship, and the type of coating that will prevent corrosion from occurring. Once the success criteria are defined, student groups are given a budget to design and engineer a ship that will meet the all of the challenge criteria. After activity constraints are introduced, the students discuss success criteria and how they will determine whether their final designs are deemed successful. Students engineer a ship that not only holds cargo but also resists corrosion.
