Stem Sims: Trench Attack


As mentioned in our prior overview of STEM Sims [], this interactive software package provides over 100 simulations of laboratory experiments and engineering design products for the STEM classroom. The simulation titled “Trench Attack” immerses students in World War I trench warfare. This simulation has the student assume the role of a military commander using chemical agents against enemy forces to win a battle. During the simulation, students explore how chemical agents (e.g., mustard gas) can affect the environment. As is the case with all STEM Sims software, Trench Attack is aligned with the Next Generation Science Standards (MS-ETS1.A –Defining and Delimiting an Engineering Problem) and is compatible with state standards as well.

The simulation provides students with a brochure (see link below) that includes a pre-assessment quiz and introductory information about the use of chemical agents in warfare. Moreover, the simulation includes background information on science and historical content. The integration of historical information is a great opportunity for science and history teachers to work together on a WWI Unit across the curriculum. 


The STEM Sims provides three separate lesson plans for this simulation (see links below), which will help you tailor it for your curriculum. As is the case for other STEM Sims packages, a multiple-choice assessment is included with a Teacher Guide.

Undoubtedly, Trench Attack is an excellent simulation that will stimulate students’ interest and engage them in learning chemistry. Moreover, the potential for the assimilation of instruction into both science and history content is an added benefit of this highly dynamic learning tool.  If you are looking for something to create a bridge between history and science, Trench Attack Makes the connection.
