sellathechemist, We have just launched #UCLChemAirPoll for 2023. We're looking for Year 5 and 6 primary school classes across London. Our students will visit a class in October, deliver a lesson where the children make predictions about where levels of NOx are higher/lower. Our students make the measurements using Palmes diffusion tubes and then return for a second lesson in December to discuss the results with the children.
There's oodles of fun and challenge for all.
