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.

Recently, there is a severe infectious disease caused by a type of coronavirus in my motherland. The latent period can be as long as 14 days and people infected can even show no obvious symptoms before they suffocate because of sudden constriction of bronchioles. Why would this happen?

*Thank you*
I can’t find any biology paper 2 videos . Are you going to making them and if yes, when ?
Sir do we need to know how protisits and fungi cause diease?
Not for GCSE. However, malaria is caused by a protist and you do need to know about malaria. I've made a video on it.
Could please, please do Physics Igcse (0625) Cambridge as i think that would be very helpful. Great video btw!
thanks lad
@FreeScienceLessons do you have any videos explaining in detail about protists and fungi??
No not in detail I'm afraid. They're not on the AQA spec in any detail.
is there a protist and fungi video
Will you be doing any a level science
when you say on other videos click on the link above both on youtube and your sight I CAN FIND NO LINK if you or any one can help pleas reply. Thank you.
He is releasing them in 2018 after all 9-1 videos are released...

I keep reading comments instead of watching the video, like idk what is happening tomorrow
2:37 awesome picture......
Is there a biology paper 2 playlist
When’s merchandise coming out

WE DO NOT TALK ABOUT THE FUNGI ON THE TOUNGUE!
I was trying so hard to not look at it omfg
Yes I saw my boy ibz mo on the advertisement!!!
where is the biology paper 2 playlist? :)
I have a question.... What topics are you expected to know for biology paper 1?
Very good video by the way
Hi and thanks for the comment. If you look at the first page of my channel, you'll see the Biology paper 1 section and the playlists in it. You need to learn all of that.
Yes! I got it know. Thanks!

Protists are covered in the videos on malaria and classification.

no
He said unfortunately some people recover from food poisoning lol 😂
He said fortunately not unfortunately
Wha_!? They weren't meant to recover! I'm gonna get caught!
Who's here not watching immediately before the 2020 exam but as part of revision in perfectly good time for the exam next year without much stress?
will you do videos on plants ??
Yes, they're coming up in the next two weeks.
i love you
Does this topic include a required practicle about antiseptic filter paper discs and Petri dishes, because it's not in the specification but BBC bitesize include it?
Yes that is required practical two and it's in the Cell Biology playlist.
Does anyone have any good suggestions for CZcams channels which teach IGCSE or GCSE geography ? If anyone can share, it would be really helpful...
nat geo? idrk
Currently in an exam
I can't find the revision work book!!!!
