Puzzling, Twisted Fibers Mark as Favorite (2 Favorites)

ACTIVITY in Interdisciplinary, Polymers. Last updated August 30, 2022.

Summary

In this activity, students will attempt to solve clues related to the chemistry of fabrics. Starting at the center of the maze, students will fill in each word suggested by the 20 given clues. Answering each clue correctly will help students solve the riddle provided at the end of the activity. This puzzle can be used in the classroom as part of the Fabulous Fibers theme celebration for 2022 National Chemistry Week.

Grade Level

High School and Middle School

Objectives

By the end of this activity, students should be able to:

  • Recognize that there is a real-world connection between chemistry and fabrics.
  • Understand that there are two main types of fibers, natural and synthetic, which are both made up of different polymers.

Chemistry Topics

This activity supports students’ understanding of:

  • Real-World Connections
  • Interdisciplinary Topics
  • Polymers

Time

Teacher Preparation: minimal
Lesson: 15-20 minutes

Materials

  • Student Handout

Safety

  • No specific safety precautions need to be observed for this activity.

Teacher Notes

  • This puzzle was created to appear in the September 2022 ChemFun section of Chemistry Solutions.
  • This puzzle was developed in hopes of being used in chemistry classrooms to promote the ACS National Chemistry Week 2022 theme Fabulous Fibers: The Chemistry of Fabrics.
  • Many of the clues used in creating this puzzle came from the wonderful articles that appear in the 2022 issue of Celebrating Chemistry. The articles are appropriate for students, so teachers might consider using them as readings or direct students to them for research as needed. 
  • Additionally, teachers may wish to add extra letters to the puzzle if they anticipate that students might benefit from some additional hints.
  • A word bank could be provided for students that might require extra assistance to complete the puzzle.  
  • An Answer Key has been provided for teacher reference.

For the Student

Instructions

Start in the center of the maze and twist and turn as you fill in the words suggested by each clue. As the letters are entered for each answer be sure to twist the puzzle and follow the directional arrows provided (not all words will be written from right to left!)

Several letters have been provided for you in the puzzle as hints.

Then, use the letters appearing in the highlighted squares in the order that they appear to solve the riddle at the end of the activity!
