Students design shoe covers that allow them to move silently over a variety of surfaces and avoid zombie detection, testing their ideas with a decibel meter, sound pressure meter or appropriate app.
Materials Needed

You need to find food and supplies and make contact with other groups of survivors. You’ve learned that a zombie’s hearing isn’t as good as a human’s hearing. This means that, so long as you don’t make too much noise, you’ll have a good chance of going undetected.

Create shoe covers that let you walk as silently as possible over different surfaces and materials.
Create shoe covers that let you walk as silently as possible over different surfaces and materials.
- Use a decibel meter or phone app to measure how loud you are when walking over different surfaces and materials.
- Which materials and surfaces are the loudest?
- Explore the different fabrics and materials you could use to make your shoe cover. Identify those that you think will be most silent.
- Create some shoe covers for one member of your team. The shoe covers don’t need to be a perfect fit, they simply need to wrap over and around their shoes.
- Test your shoe covers by walking over different surfaces and measuring how much noise is made.
- Explain how the cover helps to reduce the sound produced when walking.
