What is the best way for students to visualize compounds? From the traditional physical ball and stick models to the various online simulations the objective for all of these tools is to provide one with a visual for the different structures and patterns. This summer while facilitating a workshop, the participants and I discussed this question and while reviewing various representations we came across MolView.
This past week, as part of our Thermochemistry unit, my students were completing one of my favorite Target Inquiry Labs entitled “ A Very Cool Investigation”. We were using calorimeters, dissolving ammonium nitrate, and my students were recording the change in temperature using a digital thermometer. Some of my students had
We’ve all seen and use the so-called Aufbau Diagram. It is a mnemonic used to remember the order of “filling” of atomic orbitals during the construction of the ground state electron configurations of the elements. The presentation of this diagram is largely disconnected from any physical meaning. Here’s what we tell our students: “Memorize the diagram, learn to use it, and you’re guaranteed to get the right answer.”
As many teachers are preparing to teach online, we are revisiting posts from the ChemEd X archives like this one that might be of help. The author has updated this activity by adding notes specifically to help those teaching remotely. This post about Classkick was originally published April 22, 2016. The platform is now all web based and Doug has compiled a list of public assignments that you are free to modify for your own use.
I first stumbled upon Atomsmith at Chem Ed 2015. Totally loved the way you could pop up a number of molecules on the big screen and move them around. They had really cool stuff like showing and modeling phase changes with water. They demonstrated the ability to show quantum orbitals in which you can see all of the clouds combined and then separate the electron clouds into individual orbitals. I was all set to jump in feet first and then my heart sank...they had it on everything but chromebooks (which is what we use at my school). The presenter suggested that I contact the good people at Atomsmith. They have been working on an online version that runs on chromebooks.
Computer coding has been getting a lot of attention with the Hour of Code movement and President Obama’s recent “Computer Science for All” initiative. Just like it is no longer solely the job of the English teacher to teach language and communication skills, it is no longer solely the job of the computer science teacher to teach programming skills.
Upon sharing my array of apps with some future chemistry teachers, they asked why so many Periodic Tables? My response was “Well not all periodic tables are the same”, upon which was followed by several blank stares...Let me explain: I currently have the following periodic table apps loaded on my iPad...
Edmodo, Coursesites, Schoology…which digital learning platform is best for you? I’ve been searching for the right, free fit for me for the last three years. My journey has taken me from Edmodo to Coursesites to Schoology. I learned four valuable lessons about myself along the way that may help you make your own decision.
Over the past two years, I have immersed myself in designing mobile games for organic chemistry: founding a company called Alchemie and building a team to develop these games. The first of our games is called Chairs! (The exclamation point comes from the fact that an app called Chairs already existed in the AppStore.) The game Chairs! is what we call our proof-of-concept. Folks were a bit incredulous when we told them we design games that make learning organic chemistry intuitive and fun.
Last year while attending the Biennial Conference on Chemical Education at GVSU I had the opportunity to hear a talk that showed a video of a chemical demonstration showing the burning of magnesium metal. We have all seen many of these videos (thank you YouTube) and probably have performed this demo for our own students many times. During the video it may have been represented with a chemical equation followed by the students being asked to balance the equation or maybe even predict the products. Although the use of video including the showing of the equation nicely represents the macroscopic and symbolic representation, what was so unique about this particular video is that it also included the particulate representation embedded on top of the video of the demo. This was the first time I had seen the particulate level representation done like that and so I was intrigued in wanting to find more of these representations.
