    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. Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. 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.

    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.

They will use their knowledge of the speed of light and plank's equation to examine the energy involved in the emission of light. Finally, the students will then apply their knowledge of the emission spectrum to how the composition of stars is determined.

    Lab: Sweet, Salty and Cold as Ice

    In this lab, students conduct a micro-scale investigation to explore how various solutes affect the freezing point of water. Because of the small volume of liquid used, results are visible within minutes. Students observe what happens to the liquids as they are cooled and use their observations to infer what is going on at the particle level. They will use the results to explain the familiar phenomena of why we salt our roads and sidewalks in the winter and why freshwater lakes and ponds freeze over more easily than saltwater oceans in the winter.

    Video: Ingenious Video 3: This Sandwich Will Save Your Life in an Arc Flash

    It’s never fun when your clothes catch on fire. And while “stop, drop, and roll” may be a good idea sometimes, in more extreme cases, you need a better plan. Every day, industrial workers, firefighters, and soldiers risk fiery situations that might seem hard to imagine. In an arc flash event, for one, temperatures can jump to metal-melting levels in milliseconds. How can anyone possibly survive that? Well, take a tip from a club sandwich, because it’s all about the layers. The composite fabrics that protect life and limb in these situations rely on some incredible, multilayered chemistry, including the ability to quickly form a protective carbonaceous crust around the wearer.

    Video: Ingenious Video 2: What Birds Know About Color that You Don't

    We’ve been using pigments and dyes for thousands of years, but they’re not the whole story when it comes to making color. “Structural” color occurs when tiny nanostructures interact with light waves, amplifying certain colors and canceling others. From brilliant bird feathers to butterfly wings, mole hairs to octopus skin, structural color is everywhere in the natural world. Researchers have tried for years to harness this incredible natural phenomenon in a useful way. Because these colors are so small and complex, and therefore hard to copy, their efforts have met with little success. But novel research using a computer model based in repeated random sampling — a so-called “Monte Carlo” model — is showing promise. Using this approach, scientists have been able to mimic the gorgeous blue of the mountain bluebird in a thin film of reflective beads, leapfrogging millennia of evolution.

First, a guided inquiry activity will introduce the relationship between standard free energy and equilibrium constant with the equation ΔG° = -RTlnKeq. Then data collection regarding solubility of potassium nitrate at various temperatures will lead to the calculation of Ksp and ΔGo for the dissolution reaction at those temperatures. Students will manipulate the equations ΔG° = -RTlnKeq and ΔG° = ΔH° - TΔS° to derive a linear relationship between 1/T and lnKeq, which will then be graphed to determine values for ΔH° and ΔS°.
