Following on from my blog two months ago about our sponsorship of PhET simulations, our final instalment is now live on Learn Chemistry!

This time acid-base solutions, pH scale: basics and pH scale have been transformed from flash animations to HTML5, so they are compatible with all mobile and tablet devices.

Acid-base solutions can be used using the following starter ideas:

How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

And pH scale is suitable for middle school students up to high school with different tabs for each one within the simulation. pH: basics takes the middle school level as a simulation of its own. Use the suggestions below to start your investigation of pH.

Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!

We have been exceptionally pleased with these internationally popular simulations. In the future we will be adding into Learn Chemistry links to all the other chemistry PhET simulations!

Enjoy your exploration!

Have you got a brilliant idea for teaching science? If so, you could win  up to £15,000 to show that it works.
Let Teachers SHINE is a national competition run by SHINE and TES to find some of the country’s most innovative teachers. They’re looking for truly original ways to raise attainment in literacy, numeracy and science. The submission deadline is 27th April.

The competition is free to enter and open to any teacher working in England. Up to 10 winning projects will be chosen by a panel of judges from SHINE, TES and our corporate supporters. Each one will then receive a grant of up to £15,000. This money will fund a year-long pilot to prove that it can achieve real  improvements in the attainment levels of disadvantaged students. The most successful initiatives may then receive further funding from SHINE and the Esmée Fairbairn Foundation. To find out more, visit www.shinetrust.org.uk.
It would be brilliant if there were plenty of innovative ideas submitted to this competition about raising attainment in chemistry!

The Royal Society of Chemistry and Learn Chemistry are proud to sponsor the conversion of five PhET simulations from flash into HTML5. This means they will play now also nicely on a range of tablets and mobile devices, as well as desktop computers. They are also being updated, bringing their designs into 2014 too! The first simulations released from our partnership are Build an Atom, Beer’s Law and Concentration. These simulations are popular with teachers around the world due to the minimal language barrier and those with language included are rapidly translated by PhETs very active community.

      Beer's Law simulation

                            Build an Atom simulation

 Concentration simulation

But why? I think PhET can explain it really well in their own words:

PhET provides fun, interactive, research-based simulations of physical phenomena for free. We believe that our research-based approach- incorporating findings from prior research and our own testing- enables students to make connections between real-life phenomena and the underlying science, deepening their understanding and appreciation of the physical world.

The PhET simulations can help students visually comprehend the concepts by using animations to bring the invisible to life - Build an Atom and Build a Molecule (flash) in particular. Simulations can be explored in a freeform fashion using drag-and-drop, sliding and measurement instruments such as rulers, pH meters and thermometers. The user affects the responses immediately thus demonstrating cause and effect relationships.

All PhET animations are free to use and more can be found on their website. Look out for more RSC sponsored simulations in the next few months (pH and Acid-Base solutions)…!

It’s been a while since I last blogged, and with good reason! I have busy putting together the RSC’s theme for 2014: Chemistry and Art.
The National Gallery Faces of Chemistry videos, which were released in January, were the first offering. These three videos each focus on a different chemical technique: microscopy, SEM-EDX and chromatography, each looking at the Portrait of Alexander Mornauer. The various techniques have been used to examine the history of the painting and discover that the blue background present when the painting was purchased by the National Gallery, London, was in fact added 300 years after the portrait was originally painted! Watch these videos find out how the scientists at the National Gallery discovered this!

The next release for Chemistry and Art is that of Ionic Magazine whose latest edition has been developed in collaboration with the Royal Society of Chemistry. I’ll let Ionic Magazine explain its focus:

In each issue, Ionic Magazine will publish recent scientific developments within many areas of science that include medicine, nanotechnology, biotechnology, psychology, astronomy alongside many others. These will be current in the literature, and provide a platform for science writers, whether established in their careers, just beginning or perhaps experimenting their capabilities at science communication, to rant and rave about exciting developments within their particular expertise or interests. Beside each article will lay an artist’s representation of that very story. No graph, no figure, no formulae, instead a piece of art constructed from personal interpretation and not scientific representation. They will leave the reader asking more than can be answered. The ultimate goal: a stunning and stimulating collaboration of two traditionally contrasting worlds.

This edition focuses on the recent developments in RSC journals in the field on scientific and conservation discoveries around various types of art. The stories are deftly told without the technical difficulty of the original paper and the images are intriguing representations of the written content – make of them what you will!

We are also developing new educational content of the chemistry behind art, starting with prehistoric cave paintings all the way through to Impressionism. This will be released in batches throughout the year on Learn Chemistry and eventually all will be presented through our new, coming soon, Chemistry and Art microsite! Cave art coming soon!
Throughout the year departments around the RSC will be tailoring their content to fit with the Chemistry and Art theme. Our Cambridge Science Festival and Big Bang Fair stands will be colour themed, EiC and The Mole will have articles relating to Chemistry and Art (January’s Mole already has the story of the Portrait of Alexander Mornauer) and Chemistry World will have a special issue later this year. Thursday’s monthly public lecture at Burlington House sees Helen Storey and Tony Ryan in conversation discussing their Extreme Collaboration. Sold out, it will be streamed live and available after the event – hopefully on Learn Chemistry too!

It is my pleasure to update Learn Chemistry with a new collection of Higher Education (HE) Resources, The Chemistry Vignettes.
These Screencasts have been provided to the Royal Society of Chemistry to support Undergraduate Learning.

The Chemistry Vignettes Project is the result of a Physical Sciences Centre, Higher Education Academy funded departmental project collaboration between the Chemistry Schools of the University of East Anglia and The University of Southampton to examine the screencasting of first year Chemistry lectures. Vignettes are short, annotated and interactive highlights from chemistry screencasts envisaged as Open Educational Resources.
The resource collection can be found here or are searchable using the key word ‘chemistry + vignettes’ at the top of the Learn Chemistry home page.
You can also view all 69 videos from our Royal Society of Chemistry YouTube playlist or the Higher Education microsite.

The advantage of viewing the Vignettes via Learn Chemistry is that they have been grouped into 15 topics and you can watch these via YouTube embed or downloadable .MP4 file.
The resource topics (in no particular order) are as follows…
·         IR Spectroscopy Theory
·         Acids and Bases
·         Mechanisms of Esters and Amides
·         NMR Theory
·         Transition Metal Fundamentals
·         Synthetic Mechanisms Advanced

As I begin planning for the new Royal Society of Chemistry, Global Experiment 2014 (watch out for it later this summer) I found myself looking back fondly over the successful experiment last year which was run 21K times all around the world. Thanks to all who participated and shared all your photos and reports.
 As a result, I do want to share one last story of the experiment from Bowen School Shibalidian of students taking part.
Also as a reminder the Experiment is still open for posting for those still wanting to take part.


 Science events ’Fun with Science’ organized by the Royal Society of Chemistry Beijing Local Section with the help of volunteers from Beijing University of Chemical Technology were on the topic of food and health. We discussed why fruit and vegetables (being packed with vitamins—especially vitamin C—and fibre) are healthier than high fat/high sugar foods like biscuits and cakes—although the students did admit they enjoyed eating the latter as well! But how do we know how much vitamin C is present in different fruits and vegetables? Take tomatoes, sweet red peppers and apples: can you guess which contains the most vitamin C? In “Fun with Science” we didn’t have to guess—we used chemistry to find out!

Armed with tincture of iodine(an antiseptic which can be bought at the local pharmacy), 30 Year 4 Bowen students set out to measure the amounts of vitamin C in weighed amounts of the tomatoes, sweet red peppers and apples. When the dark brown tincture of iodine solution is added drop by drop to a solution containing vitamin C it undergoes a chemical reaction which turns it colourless. However if the solution also contains cornstarch, when the vitamin C has all been used up the next drop of iodine solution reacts with the starch to make a dark blue–black colour.

The students had great fun mashing up their samples of fruit and vegetables to release the vitamin C and after dissolving it in water and adding starch solution, carefully counting the number of drops of tincture of iodine they had to add to the rapidly stirred solution before it went blue–black. And what was the result? They found that the apple needed slightly more drops of iodine solution than the tomato before the solution went blue–black, but the sweet red pepper needed many more drops, showing that the vitamin C content of the pepper is much higher than that of apples or tomatoes.

But although the students now knew red pepper contained the most vitamin C, they still didn’t know exactly how much—how many milligrams (mg) of vitamin C are contained in one gram (g) of fruit or vegetable. To do this they needed to react their iodine solution with what we call a “standard solution”—one containing a known amount of vitamin C. Fortunately vitamin C tablets contain exactly 1000 mg of vitamin C, so by dissolving one tablet in 1000 milliliters (mL) of water they were able to make a standard solution containing 1 mg of vitamin C in every mL of solution. 
Using this solution they could then find out find out how many mg of vitamin C correspond to each drop of iodine solution and finally calculate the amounts of vitamin C in their samples. The average results for the class were:
Tomato                     0.19 mg/g
Apple                        0.22 mg/g 
Sweet red pepper    0.72 mg/g

This was a special “Fun with Science” session because it was part of the Royal Society of Chemistry’s Global Experiment for 2013. Children from hundreds of schools all around the world have carried out the same experiment and uploaded their results onto the Royal Society of Chemistry website. So now Bowen School Shibalidian is really on the map!
Every pupil who takes part in the Global Experiment and submits their data receives a certificate from the Royal
Society of Chemistry, and the Bowen students were delighted to receive theirs at the end of the experiment—just like their fellow students all over the world.
The Royal Society of Chemistry’s General Manager for China Dr. Amy Lam and Chair of the Beijing Local Section Prof. David Evans and the team of volunteers (below) presented certificates.

After a fabulous 2013, during which Learn Chemistry embarked on ambitious plans to advance online assessment, online experimentation, and build fascinating content partnerships, and won an award, we're looking forward to much more in 2014.

The Learn Chemistry team, and colleageus from across the Royal Society of Chemistry's Schools and Colleges team, will be attending the Association for Science Education conference 2014 in Birmingham from the 8th January.

Learn Chemistry Partnership, a project from our sister Networks team, will be the order of the day at ASE 2014. If you're visiting, make sure you say hi. If you're a teacher, register your school to be a Learn Chemistry Partner, and qualify for some great benefits.

Later in January, we'll be at BETT 2014, in the cavernous Excel Centre in London's Docklands, and we'll be crossing our fingers that we win an award this time! Come and stop by our snazzy stand if you're at BETT this year.

In the meantime, here's a nice nugget from the National Stem Centre's resource blog, on using podcasts in the classroom. Why not give their suggestions a try with some of our own podcasts for primary and secondary students.
