  Video: Ingenious Video 7: The World has a Receipt Problem

  The receipts you take home from the store – or stuff in your bag, or lose in your car -- employ a printing method that’s been around since the 1970s. Thermal printing involves heat-sensitive inks called leuco dyes that show up when they react with an acid developer embedded in the paper. Not only do these inks fade easily, but receipts that use them aren’t recyclable, and could even be dangerous to your health. Taking a cue from a failed experiment, scientists are developing a new kind of receipt paper that will use the same thermal printers without leuco dyes. Instead of acid developers, this paper is coated in reflective microspheres that collapse under heat, allowing regular ink underneath to show through.

  Activity: Ingenious: The World Has a Receipt Problem Video Questions

  In this activity, students will answer questions while watching the video The World has a Receipt Problem from the Ingenious series produced by the American Chemical Society.

This episode investigates the process of thermal printing on receipts, and the limitations related to the paper that currently prints using leuco dyes. This heat-sensitive ink appears when it reacts with an acid developer embedded in the paper. Scientists are working to develop a new kind of thermal receipt paper, that can use the same printers, however it offers many additional benefits and potential uses.

  Lesson Plan: Chemistry Basics Unit Plan

  The AACT High School Classroom Resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We searched through our resource library and constructed a unit plan for introducing the basic chemistry concepts to students: Laboratory Safety, Equipment, and Reports, Periodic Table Basics, Physical and Chemical Properties and Changes, Endothermic and Exothermic Changes, and Classification of Matter. These topics are very important for your students to master before they dig into other chemistry concepts. This unit is designed to be used at beginning of the school year.
