I'm about half-way in and noticing a rather obvious trend.
You start off with an organelle, and then say it's like this particular city building.
You then say what the organelle does in brief.
You then say what the city building does and how it's like the organelle.
You did this atleast a couple of times, and you're not giving much information, and just restating the similarity multiple times.
Do you have a script written down before you start recording?
It might help you to learn a slightly more informative script. You'll also have less stuttering, and will be less likely to repeat yourself.
You should also consider showing other diagrams about the organelles. Particularly where they are within a cell.
Also, mentioning that you're describing the organelles in a normal Animal cell.
Perhaps saying where there are differences in certain types of cells, such as nerve cells, or sperm cells. Or comparing to plant cell structure. For example the cell wall, which isn't found in animal cells, or the presence of a chloroplast.
Or the different sizes of ribosomes you find between animal cells and bacterial cells.
Those sort of comparisons you could have worked in by describing it as comparing different settlements. A bacterial cell can be much more basic than an animal cell, so it's more of a town than a city.
Or a plant cell is more fortified and more industrious.
Perhaps you should describe some more detail about the specific organelles.
Such as the structure of cell membranes being phospho-lipids, or how they use protein pumps to allow larger polar molecules in. (Perhaps say this is similar to using a tool like an airplane or ship to bring in larger vehicles and objects).
I'm not sure what degree of knowledge you have on the subject of cells, because it's very basic in your video.
There were places where you were very vague. Such as describing the things a mitochondria does. You started of by saying "It's pretty obvious what I'm going to say for this one", but it's not. Most people don't know what a Mitochondria does.
You could have described it's use in the production of ATP during aerobic respiration.
I'm not saying to give up on the videos, because it's brilliant that you have a healthy interest in science.
And you should continue to make more videos, and try to put in more detail, since it will help you to learn.
If you have any questions regarding biology, then make sure to ask your teacher or consult a text book.
I'm only studying Biology at college, but if you have any questions, I can try and help too. It'll be good to reinforce each others knowledge.
