When introducing acid-base theory, the concept of indicators and their pH color changes is usually discussed. To illustrate some color transitions to students, a classroom demonstration has been devised based on a memorable scene from Disney’s 1964 movie Mary Poppins.
Chad Husting uses a few simple gas law experiments to introduce his students to the particulate level of chemistry.
A primary goal of modern education is to prepare students for a globally competitive society. Importantly we must ask questions such as, “who is doing the hard intellectual work in the classroom?” and "what does doing hard intellectual work look like?"
The familiar soda fountains that can be produced by adding Mentos candies to plastic bottles of carbonated beverages can also be produced by adding objects to carbonated beverages in aluminum cans. A variety of simple methods for producing soda fountains from cans are described.
Chad Husting explains how he used two hands on activities to get a sense of where his students were at within the realm of labwork and the scientific process as school began.
Yes, sitting down and having "The Talk" with your students- the one focused on their careers and goals. Sometimes it is difficult and each student can be very different. But it is still worth it in the long run to do this.

Michael Jansen reflects on a very common empirical formula lab that asks students to determine the empirical formula of MgxOy. He then explains how he continues to use it as a "successful failure", how he demonstrates an alternate procedure and leads his students to an important lesson.
Can you use your knowledge of chemistry to figure out what is going on in this blue/green/yellow/blue color change?
The two-page instruction sheet that accompanies the Luster Leaf Rapitest© Soil Test Kit could be a useful curriculum resource for chemistry teachers for generating discussion about the key aspects of the content or for helping students practice close reading skills. This article will briefly describe the contents of the instruction sheet and suggest possible uses in the general chemistry curriculum by posing questions for students to answer or consider.
