    In this video, we look at pathogens. We explore what is meant by a pathogen and look specifically at bacteria and viruses. We then look at how pathogens spread and what we can do to reduce the spread.

    The intro to these videos is like getting into a hot bath - i see “science” and i feel pain - but the actual video is like the rest of the bath, calming and invigorating, good for the mind, body and soul, something to get me energised and calm me down, to help me with the stresses of life. Thank you, shaun.

    I just want to take time out of my revision to thank you as your channel has helped me achieve the highest possible grades I know I'm capable of and with the help of your videos and latest content for the 9-1 GCSE's my grades continue to climb higher, all thanks to you. Please continue what your doing as I'm sure that I am not the only one benefiting from this content. You are the reason many people are able to pass their GCSE's so please don't stop what you're doing. Thank you.
