Hi I'm Katie! I am a secondary school science teacher and general space nerd. I studied astrophysics at Sheffield University before embarking on a PGCE at Bristol University. That was in 2016. Since then I have taught in the UK and around the world before settling down with my laptop as a full time online tutor in 2018. I am a firm believer that practicals are the best way to learn important concepts in science. So if you want a teacher who simply loves science (all of it, not just space!), who loves experiments and who oozes enthusiasm then you're in the right place!
