This hands-on activity walks through paper chromatography, a technique used by chemists to separate mixtures or in forensic crime analysis to investigate evidence. Paper chromatography can be applied outside of the lab too! Here, we use the method to show what types of dyes make up different colored markers. Is purple truly made of red and blue?
We all love things that glow in the dark and a night time celebration isn’t complete without glow sticks, but have you ever wondered how they work? What exactly happens to make light appear when you bend the glow stick and hear that crack. Learn about chemiluminescence and the chemistry behind glow sticks!
Believe it or not, you have some of the same technology in your phone as the Perseverance rover on Mars! The electronics devices you use every day like your cell phone include a lot of high-tech materials made by DuPont Electronics. This sounds very complicated, but some materials are actually based on a chemical process called Copper Electrodeposition, which you’ll learn from high school Chemistry Lab.
