Science Practice: Developing and Using Models
Solutions of copper (II) dissolved in acetone are easy to prepare, and can display orange, yellow, green, and blue color depending upon conditions. Such solutions allow for a variety of demonstrations and experiments that illustrate principles of chemical equilibrium.
Chemistry and lasers can be used to create a demonstration that includes several colors and flashing lights. This demonstration connects to topics in quantum chemistry and phase changes.
I had the opportunity to develop an advanced chemical lab design course for a small group of ambitious students. I have outlined the resources I used and how I pulled the course together,
I have been using magnets of elements and subatomic particles for some time to help my students visualize what is happening at the particle level of chemistry. I now have more tools to use and I hope you follow me and explore what we can do with them to help our students.
With few materials available to complete wet labs in my school, I have to be creative with covering lab concepts in my AP chemistry course. I was looking for a way to make sure my students were getting the idea of the macroscopic changes that take place in a galvanic cell without necessarily being able to do the wet lab. The particulate model that is part of the Energizer Lab inspired me to write an end of unit assignment for my students using Stop Motion video apps.
Have you ever seen the liquid nitrogen cloud? Do you wonder how the cloud forms when hot water is thrown onto liquid nitrogen? This post explores the liquid nitrogen cloud and possible explanations for its formation.
Use Mega M&Ms, M&Ms minis, and regular M&M’s in this activity to examine the concept of isotopes and average atomic mass. The color of the M&M’s represent that they are the same element and have the same number of protons. The size represents, in a relative sense, the different numbers of neutrons.
Organic Chemistry is overlooked as a first year chemistry topic in most areas, but it can be a very valuable and fun experience for students. This is an activity that can be used to introduce students to functional groups.
For dynamic equilibrium, I like to use a physical analogy that pits students against each other in a classroom-wide “snowball” fight. Not only is this activity great for building students’ conceptualization of dynamic equilibrium, it is also really fun!
