#GardenIndicators was a collaborative project held on Twitter during the first lockdown in 2020. It involved like minded chemistry enthusiasts who evaluated plants from their gardens as pH indicators. It would go on to involve over 28 different people, and include over 170 different investigations. The results were collated in a spreadsheet using RGB values to represent the colour changes seen during the experiments. This poster was entered into the Royal Society of Chemistry Twitter Poster Conference 2021, and won first prize in the 'Primary and Secondary Education' category.
