Use magnetic chess as a brain break during chemistry class to help introduce potential energy versus interparticle distance graphs in a memorable way!
Adding dyes to salting out experiments can create a variety of interesting color effects as the dyes differentially dissolve in the aqueous and organic layers. Can this differential solubility of dyes be explained using intermolecular forces as a guide?
Josh Kenney explains an innovative POGIL-like approach to teaching stoichiometry, integrating LEGO pieces. Addressing student difficulties with stoichiometry's abstract nature, he designed a custom LEGO activity inspired by existing resources, promoting collaboration and enhancing conceptual grasp. This engaging approach primes students for complex stoichiometry challenges.
In this enrichment activity, students research elements to prove that their element is the most lethal of all in the March Madness Element Bracket.
Polylactic acid (PLA) exhibits a glass transition from hard and brittle to soft and rubbery when immersed in boiling water. PLA-based structures containing a small metal object can be used as rattles when they are shaken. The sound of the rattles change when they are heated above or cooled below their glass transition, enabling them to be used as demonstrations.
Pharaoh's serpent is the name of a very interesting chemical reaction that produces a snake-like foam. Unfortunately, it requires the use of a toxic mercury compound. Explore this very similar reaction that can be achieved quite simply by using fuel tablets and calcium gluconate tablets and learn a lot about the chemistry that is involved!
Students may have been using the metric system as early as in elementary school, so why do they struggle to use it in first year chemistry class in high school? This is a quick idea to help you reintroduce the metric system in your class.
Dean Campbell uses demonstrations and props to illustrate concepts while teaching his collegiate Materials Chemistry course. Many of the examples described are also suitable for use in high school and collegiate General Chemistry courses.
What is some of the chemistry involved in the formation of ice clouds when boiling water is thrown into icy air?
Discover the secrets behind flame-shaped highlighter markings that not only disappear and reappear but also glow and flicker under the influence of acids, bases, and UV lights.
