Here at LearnSciHQ we’re working hard on developing new interactive resources in chemistry and the biosciences for an autumn 2019 release. We’ve already covered our summer innovations in bioscience resources, so now let’s find out how we’re expanding the chemistry library.
Please note: the images here represent pre-release builds and may be subject to change.
New Chemistry Resources
As always, we want to ensure Learning Science resources are valued by staff and students. As part of this we select new topics based on requests by our partners. Over the past year our most requested fields were safety, electrochemistry, NMR spectroscopy, IR spectroscopy and thin layer chromatography. We are delivering resources in each of these categories, as well as filling a few specific gaps in other fields.
No matter what topic your students are studying in the lab, safety is paramount. We have developed two new resources to help ensure students can work safely and confidently to help them get the most out of their lab experiences.
One of these involves getting your students used to the idea of dressing safely for the lab, learning which items of clothing are safe and which pose a safety risk, and why. In the second resource, students explore a lab environment and answer questions at different points. In doing this, students can familiarise themselves with the risks and key safety features of an active laboratory.
We appreciate safety protocols can vary a lot between labs so just let us know if you'd like these resources customised or more specific ones built for your institution.
Electrochemistry is a branch of physical chemistry that we are breaking into this year with interactive activities in cyclic voltammetry.
One resource covers how the shape and position of a cyclic voltammogram (CV) may be affected in a chemical reaction. Students can explore the relationship between scan rate and the timescale of the CV.
Do you work in electrochemistry and have further ideas of resources you’d like to see? Let us know!
We’ve also had great interest in NMR spectroscopy. We’ve added to our existing NMR spectrum interpretation simulation with a pair of resources on sample preparation and relaxation theory.
Students can practise preparing a sample for proton NMR analysis and learn how to improve the results of their analysis by using the correct technique and avoiding common errors.
In our NMR fundamentals resource, students learn about the instrumentation and the process of nuclei relaxation in NMR spectroscopy. They can explore concepts including nuclear spin and how nuclei behave in the presence of an externally applied magnetic field.
Another commonly used analytical tool is infrared spectroscopy. Students can explore the underlying theory of the technique and actively engage with concepts including vibrational energy levels, harmonic oscillation, Morse potential and the different modes of bond vibration.
In our ‘Recording Infrared Spectra’ simulation, students can investigate the importance of recording a background spectrum and practise correctly recording IR spectra of a liquid and a solid sample.
Thin Layer Chromatography (TLC)
Building on our existing resource which helps students to perform a simple TLC set-up procedure, we’ve created a new activity that explores solvent mix and sample separation. The new resource looks at the relative polarities of different compounds and students can trial different phases and solvent compositions to optimise their experimental design.
We’re looking forward to continuing the design and development of these resources over the summer, and then planning ahead for the future. If you already use the Learning Science chemistry library, you can expect to see the new resources ready for embedding into your course for the start of term. If you’re new to Learning Science and think that these, or any other chemistry resources look relevant to your teaching, contact us to arrange a demonstration or request a free trial.
