Optimizing Fire Hydrant Placement in Urban Grids for Efficient Firefighting

This activity encourages students to explore effective fire hydrant placement within a city grid, enhancing firefighting efficiency. With the fire department's 100m hoses, students assess an 8-block layout to determine the minimum number of hydrants needed for optimal coverage. Using Flash interactivity for modeling and PDF tools for recording findings, learners engage in a hands-on investigation of urban planning and resource allocation. The exploration also includes an inquiry into the design and appearance of fire hydrants in the UK, promoting both mathematical reasoning and practical knowledge.

Presentation Transcript

  1. Nuffield AMP Fire Hydrants

  2. Firefighters use hydrants to connect their hoses to the water mains

  3. Imagine a city where all the streets are laid on a grid and all the blocks are 100m squareThe fire department have hoses that are 100 m long, so they don’t need a hydrant on every street-corner

  4. Here are 8 blocks arranged in a 4 x 2 grid One hydrant has been placed at the corner of one block Discuss where you might place other hydrants What is the minimum number you need?

  5. Investigate for different sized grids You can model the activity using the Flash interactive, counters, pupils, ... Pupils can record their explorations using the PDF interactive

  6. What do fire hydrants look like in the UK?
