In our 900-watt microwave, this took about three minutes. I popped the corn on high until the popping subsided to one kernel every 10 seconds.

For the microwave popcorn, following the manufacturer’s instructions, I added the corn to the bowl and secured the vented lid.

After I'd added the kernels, I kept them in motion over medium-high heat until the popping settled down to just one every 10 seconds. After removing the tester kernels, I poured in the rest of the corn. Because popcorn acts as its own thermometer, once those test kernels popped, I knew the oil was at the ideal temperature.

For both the stovetop and the Whirley-Popped corn, I first preheated the oil over medium-high heat with just a couple kernels.

While it's not a chemistry app, it is highly recommended by a number of teachers for checking your students' understanding during lessons. And … SocrativeĪn honourable mention must go to Socrative (free, iOS, Android).

You’ll also see many more online-only articles to support teaching, and be able to download resources, teaching ideas and worksheets linked to our articles. You’ll be able to find all of the articles from our print magazine on this site in a format designed for reading on a phone, tablet or desktop computer. Updated June 2018: We have retired the Education in Chemistry mobile apps and online web reader. When you're finished in the lab, the app will create a lab report you can share. Make a reaction and you'll be given the equation. Select from a range of solids, liquids, gases, solutions and equipment. There's no guidance or tutorial, it's just a lot fun to play with.

This is a chemistry lab in the palm of your hand ($4.99 (£3.09), iOS, Android, trial version available). Thanks to Patrick Thomson for recommending it. This is a fun little app that does one thing and does it well. She needed something to help her students practice identifying axial and equatorial bonds in flipped cyclohexane conformations, and so Chairs was born. The idea for this app (free, iOS) came from Julia Winter, a chemistry teacher in the US. Look up data, download spectra and find links to articles. Karel Berka recommended this app as he uses it with his students to find information and resources about chemical compounds.ĭraw a structure or enter a name and ChemSpider searches the Royal Society of Chemistry's database of over 35 million structures. Updated July 2019, the ChemSpider app has been removed. There's also a test mode that's useful for self-assessment – students construct inorganic and organic compounds, and hints are available if they get stuck. It's designed for students to draw structures, view them as 3D models, visualise atomic orbitals and see electronic effects. 3D molecules edit & testĮducation in Chemistry reviewed this app ($3.99, iOS) back in 2012. Adjust the temperature, change the volume of the container and add more atoms to see the effect on pressure. You control the atoms in this simulation of particle theory.

Tindarapo was the first of many to suggest Atoms in Motion (iOS, student version free, full version £2.99). You can save and email the structures you draw. It's not cluttered with features, it does the job slickly and simply. Paul Coxon recommended Elemental (free, iOS), a simple tool for drawing chemical structures and reactions. There are podcasts and videos about the elements, too. Students can see the trends in electronegativity and atomic radius overlaid on the table. It's packed with features, such a slider that shows how the elements change as the temperature increases and the discovery of the elements as you scroll through history. There are lots of periodic table apps available, but this one (free, Android, iOS) is based on the Royal Society of Chemistry's successful interactive website. Here's what they suggested, with some favourites of our own. There are lots of chemistry apps out there, but which ones are actually worth installing? We asked teachers for their recommendations, what they use in the classroom and which apps they recommend to students.
