It has been claimed that because all water ultimately ends up in the water cycle, we drink water that the dinosaurs peed out. What does chemistry have to say about this assertion?
Tissue paper can be folded and cut with chemistry-related patterns to make decorative paper banners that can be used as Mexican-themed decorations. Chemistry concept connections include lattice energy, bandgap energy, and ionic crystal fracture.
The floating soap bubble is an impressive experiment that is surprisingly easy to carry out.
With a little chemical investigation, you can figure out how Jet-Puffed's new color changing marshmallows work!
Placing dry ice in limewater is a great demonstration to accompany discussions on a variety of chemical topics, including the impact of ocean acidification on marine organisms that depend upon the formation of CaCO3.
Learn the chemistry behind the reaction between calcium carbide and water...melon...?!
This timely post is a perfect fit for the theme of Chemists Celebrate Earth Week 2023! Algae is a rich topic with many possible connections to the chemistry classroom. Algae needs to take in light, carbon dioxide, and various simple nutrients and, though it can sometimes get out of control, can produce oxygen, diatomaceous earth, and other products. It can even fluoresce pink!
Laser cutters can be used to cut and engrave a variety of thin materials. Compact discs, composed of layers of polycarbonate plastic and aluminum metal, were explored for their ability to be shaped with a laser cutter. The laser can successfully cut and engrave the compact discs into the shape of snowflake. However, each disc must first be coated with a material like glue in order to protect the plastic from discoloration and the byproducts from cutting the plastic that can accumulate on the disc surface.
Diffusion of HCl(g) from concentrated solutions of HCl can be used to illustrate some chemistry related to the train accident in Ohio.
Some metals and metal alloys undergo a transition to brittleness at cold temperature. This phenomenon likely contributed to the demise of the Titanic.
