Elemental Haiku

Hydrogen haiku

In the August 4th issue of Science Magazine, author Mary Soon Lee shared a review of a periodic table that contains haiku for each element. There is an interactive periodic table you can click on; it was easily viewable in the mobile version of the article. This would be great when wanting to include interdisciplinary components or when reaching students whose interests include poetry. Students could be instructed to devise their own haiku for an element using properties that are specific to that element.

DIY Vapor Catalyzed Chemiluminescence

I recently watched a video in which a chemist (who goes by the nickname “NurdRage”) activated a chemiluminescent reaction by vapor deposition. I wanted to try it out for myself! Unfortunately, oxalyl chloride is toxic, corrosive, and a lachrymator. Thus, the experiment conducted by NurdRage needs to be conducted in a hood, and it is not particularly amenable to simple presentations. I began to wonder how I could create this vapor activated chemiluminescence using simple materials.

Chemical Mystery #10: Out of the Blue!

In this simple trick, colors are made to "magically" appear and disappear on a straw. This science experiment is very easy to do...if you know your chemistry!

Reduction of Permanganate Ion by Acids in Rhubarb, Apples, and Candy

Apples

If rhubarb stem is placed in a solution of permanganate, the purple permanganate ion is reduced to the colorless Mn2+ ion. It is thought that the oxalic acid present in rhubarb causes this reduction. The investigations presented in this post provide evidence that this may not be the whole story...

Exploring the Diet Coke and Mentos Experiment

I think this experiment provides a fantastic vehicle to involve students of all ages in small, hands-on and exploratory research projects. Like many others, my students and I have investigated various aspects of this interesting fountain.

Investigations of Chemicals in Natural Food Coloring. Part 3: Sunflower

Fluorescence of sunflower dye

The chemistry of the Sunflower dye found in McCormick’s Color from Nature food dyes is explored in this post. This is the last in a three-part series in which several experiments and demonstrations that can be done with Color from Nature food dyes are described.
