Key Stage 4

Activities and Events

Chemical Supermodels

Using Molymod kits and pictorial instructions to build models of a wide variety of molecules, from simple gases to complex drug molecules involving tens of atoms.

Chemistry at Work

This is one of Yorkshire’s best established events for young people, part of a wider objective to support the advancement of the chemical sciences.  Hosted annually in the University of York YSOC labs the event attracts around 500 young people from Key Stages 3 and 4. Through a series of hands-on interactive workshops and demonstrations, students are introduced to chemistry in an industrial context - linked to their learning and curriculum - and shown the wide range of career opportunities and pathways available.

NYBEP run the York event on behalf of the Royal Society of Chemistry. Details of the national Chemistry at Work series can be found on the RSC website.

Chemistry Careers Talk - Why Study Chemistry?

When students are studying for their GCSEs (or equivalent) they may not yet be thinking about their options in the future. Many are not aware of the opportunities available to them. There is a widely held belief that all chemists wear white coats and that a degree in chemistry can only lead to a life in the lab. We can present a short talk, which shows students that this is not true; pointing out why students may wish to study chemistry at university and alerting them to the wide variety of career opportunities a chemistry degree opens up, both inside and outside the world of science. Importantly we include information about sensible choices of post-16 subjects that will keep their scientific options open in the future.

Chemistry on Cue

Can you make a chemical “clock” that changes colour on cue? This activity uses the iodine clock reaction to explore reaction rates.

Colourful Chemistry - Demonstration Lecture

How have chemists brought colour to our lives? Why do chemists use colour to help them understand the world around them? What makes fireworks look so pretty? The answers to these and other burning questions will be answered in this exciting lecture, delivered by Dr Annie Hodgson from the University of York. Prepare to be amazed as colours change before your eyes, but don’t be surprised by the odd flash or bang along the way.

CSI-The Great Jewel Robbery

Barchester Grange, the home of Lady Agatha Ponsonby-Smallpeace, has been burgled. The safe in the study was opened and a collection of jewellery, worth an estimated £750 000, was taken. There are a number of clues at the scene, which may point to the identity of the main suspect for the crime. Chromatography can be used to compare black ink from a note left at the crime-scene with the ink from pens belonging to the suspects. Using microscopy, slides of fibres taken from the clothes of all the suspects can be compared to samples taken from the scene of the crime, to see if any matches can be found.

Discovering DNA and Molecules for Life

There are three parts to these activities, which can be delivered together or separately to create workshops of varying lengths. The activities involve model building, bracelets (“my name in genetic code”) and extracting DNA from kiwi fruit.
1) The most popular workshop takes about an hour and incorporates a lecture about the structure and function of DNA (fully illustrated). There is then a model-building workshop, led using a computer-animated version of the exercise. The model kits used are produced by Molymod. We build a sense strand of DNA (nine bases long) starting with nucleotides. By base-pairing we complete the molecule. We then use the anti-sense strand to make m-RNA and from that pick the three transfer RNA molecules required to bring in the three amino acids to build the tripeptide coded for by the gene. Each pair of students has a different sequence and were the sequences to be joined together it would produce the first part of the gene for the beta-strand of haemoglobin. This gene has been chosen, because quiet near the start is the position for the point mutation that leads to sickle cell anaemia.
2) A slightly longer (add about 15 min) version of the workshop has the activities above plus an exercise to make a bracelet in which the students each write their name in genetic code (the 4 bases being represented by 4 different colours of beads.) This is a bit of fun, it reinforces the message of the triplet code and the students are allowed to keep the bracelet.
3) The longest version of the workshop takes half a day and incorporates 1, 2 (if required) and a wet-lab exercise in which we extract DNA from kiwi fruit. This is incorporated into the other exercises in order to accommodate an incubation step. The workshop requires separate areas to do the dry exercises away from the wet benches (the kiwi exercise can get very messy).

Incredible Indigo

This workshop takes about half a day (but is best if it can be done with a lunch break half way through to allow the sample of indigo to dry). The practical is in two parts. In the first part there is a brief introduction to indigo and then we synthesise some indigo. In the second part we weigh the (hopefully) dry sample of indigo (to calculate the yield), before reducing it to its soluble form, which we use to tie-dye a piece of fabric and then watch it oxidise back to the dark blue form. The nice thing about this practical is that students get to keep the fabric as a reminder of the activity. As an extension activity, students can calculate the atom economy of the reaction.

Just a Minute

Blowing the tops off film canisters with sodium hydrogen carbonate (bicarbonate of soda), citric acid and water. This is great fun, but not for those with a nervous disposition! If it is dry weather, you can do this outside as it is rather messy, but it is fine indoors with care. The challenge is to work out how much of each of the ingredients is required to blow the lid off the film canister in exactly one minute.

Science Trail

This is an annual event in which school parties spend a day at the University of York campus taking part in a range of activities delivered by the various science departments (including chemistry). Accompanying teachers are offered a day of Continuing Professional Development at the National Science Learning Centre.

The Science Trail usually takes place every year in March.

More details are available on the University of York Science Trail webpage.

Spectroscopy in a Suitcase (SIAS) - Infrared

These infrared spectroscopy activities are designed for post-16 students and those aspiring to study chemistry beyond GCSE level. Note that these activities are only available at times when we can access the University of York’s chemistry teaching laboratory in order to be able to use the instruments.

As an alternative, schools may wish to book a Spectroscopy in a Suitcase (SIAS) kit from the Royal Society of Chemistry (RSC). The SIAS scheme provides equipment and resources to use in schools, enabling students to get hands-on experience of spectroscopic techniques. 

Formula 1 diagnostics

Infrared spectroscopy is routinely used to check the performance of and locate faults in Formula 1 racing cars. Students run IR spectra of fluids leaked from cars to identify where the faults might be, through pattern matching with sample spectra.

Festival drug testing

Those policing large music festivals use infrared spectroscopy to quickly identify substances that may potentially be illegal drugs. Run IR spectra of a range of white powders to identify them by pattern matching with sample spectra.

Drug purity

Infrared spectroscopy is used to check the purity of pharmaceutical products. Use IR to find out if the samples of aspirin or paracetamol you have synthesised are pure or contain contaminants.

What’s in the pot?

Traces of materials have been extracted from fragments of pot found at an archaeological site. Try to identify them by comparing their infrared spectra with those you run of drinks and foodstuffs that might have been stored in the pots.

The art of chemistry

Infrared spectroscopy is a non-destructive technique that can be used to help identify materials (such as paints, pigments and varnishes) used in fine works of art. This is useful to those restoring artworks, as well as those trying to spot fakes!

Spectroscopy in a Suitcase (SIAS) - Ultraviolet-visible

Light comes in a rainbow of colours and can tell us so much about the universe around us. Spectroscopy is a way to investigate these colours, revealing the chemistry happening in a test tube or in a galaxy far away. Using a portable Spectroscopy in a Suitcase kit, originally developed by the Royal Society of Chemistry (RSC), participants can engage with a range of demonstrations to discover the properties visible and ultraviolet (UV) light.

For further details about SIAS you can look at the RSC Spectroscopy in a Suitcase website where there are some resource packs available to download. It is envisaged that more teaching materials will be added to the site, so if you produce any resources using the SIAS kit that you would like to share, please let us know.

Even more resources relating to SIAS are available from the RSC SpectraSchool website, and from there you can find information about many other fascinating areas of chemistry.
