Did you know that sand can be converted into a mixture of gases that spontaneously ignites in air? The procedures involved are relatively simple to perform, spectacular to observe, and relate to a rich assortment of chemical principles.
A lab practical with an escape room story turned out to be a great final exam.
The Types of Chemical Reactions Lab is a favorite for many teachers and students. Chemistry comes to life as students record observations. This virtual version by no means replaces the students physically conducting the reactions themselves but during these times this activity can be used to supplement the teaching of chemical reactions.
As teachers, we can leverage fruitful discussions about chemical control with students to elicit more about students' initial ideas and ways of reasoning. From asking students to clarify their own thinking, we can identify students’ own productive ideas that we can capitalize on to advance their thinking.
A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students, regardless of whether they pursue further studies or careers in the sciences. Follow this series of articles to find out how the Element of the Month Project began and how the elements are presented. #IYPT
Embracing the idea that students already create an image, create an idea, of what is happening when they observe a demonstration, lab or activity. The goal is to have the students make that model more concrete through drawing it.
The recently published iPad app ChemTube3D (and related website for classrooms without iPads) will be discussed. It has a great deal of functionality - including a large selection of organic mechanism animations and models of structure and bonding.
Augmented reality is a type of technology that uses an app to turn a hidden QR code into a three dimensional object on a screen as viewed by your camera. Elements 4D attempts to bring augmented reality to chemistry.
Looking over my student's papers, there may have been more misconceptions created because of the way I planned the curriculum. In all of the experiments students can see and observe that not all of the crystals or material dissolves yet the water starts to conduct. In their minds there is evidence that they believe either something DOES dissolve or it does NOT. Clearly, partial dissolving is initially too much to consider.
