Ryan Johnson and I took a trip to the top of Pikes Peak to study the Coke and Mentos experiment. And we had a few surprises along the way...
Egg cartons and beverage holders can be used as models of atoms, with their dimples representing orbitals. Each dimple can hold up to two objects such as milk jug caps, plastic eggs, and cup pieces to represent electrons in the orbitals. Partially overlapping the trays by stacking the dimples represents chemical bonding and produces molecular models resembling Lewis structures. The models can be easily made from materials that can be readily found grocery stores and fast-food restaurants.
Explore chlorinated hydrocarbons and dipoles with paper and toy models like LEGO, K’Nex, and Lux Blox! Paper models reinforce molecule polarity lessons, with templates and assignments included in the Supporting Information.
Recent space-related phenomena like aurora and a comet were viewed by large numbers of people. These phenomena can be connected to concepts described in chemistry courses, such as electronic structures and light emission associated with species such as excited oxygen atoms.
A Picture-Perfect activity for National Chemistry Week 2024!
This chemical reaction is just plain weird...but also beautiful!
Grinding solid colorless phenolphthalein indicator and solid colorless magnesium hydroxide base can produce a reaction that causes the mixture to turn pink.
How do Melissa & Doug’s “Water WOW!” Water Reveal coloring books work? Let's do some experiments to find out!
Helical structures can be built from media such as LEGO bricks and paper. These structures can be used to model helical structures in chemistry. These include circularly polarized light and various helical biomolecules.
