Thanks so much for this video. I have mocks today and know nothing about the kidneys. Very clear explanation and detail. Summarized 4 lessons in 15 minutes. Just subscribed.
amazing video, which exam board do you specify your videos for ?
He does EDUQAS
thank you for linking the topics! very helpful, thank you! 🤩🙏
Thanks you for your teaching
why do you multiply them
find the percetange of each
I'm 60 and taught in university most of my years. I see some excellent pedagogy here. A 5-7 min B&W chalk talk where students follow the pen as the story evolves is in my opinion among the best teaching styles from perspective of reaching an intended learning outcome like weakest students keep up with strongest students. In your case, your writing is neat, so this style works well for you. I'd argue this would have been harmed by use of color. There is a need for some amount of teaching to not be Powerpoint or problem based learning, which would require more time, which might cause some de-focusing. Nice job!
thank you!!! 😎😝
Thank you so much
Thanks 👍 alot
This is fantastic. I didn't cover this in my Biology course so your explanation was really helpful.
Thank you for the video!!
