"What a Big Mouth You Have," "The Better To Eat You With"

Hi, people!!! As all the good things in life, even Biology Season 1 comes to an end. So, welcome to (thankfully) my last post of the year!!!

 

Well, getting down to business! I'm posting today some videos on Digestive system for you to review (We are just 4 DAYS AWAY from the integrative test!!!)

The tittle of my post is what my favourite wolf told Red Riding Hood!!!

 But, for reals, we know that what you really need is not a big mouth, it's a lot of right enzymes working at the correct ph...

Well, getting down to business! I'm posting today some videos on Digestive system for you to review what you have been studying for next Monday.

VIDEO 1





VIDEO 2

VIDEO 3 a great video on a general vision on DIGESTION

 
And last but not the least, Video 4, a funny video made by two students




Would you like to see the REAL effects of Hydrochloric acid (as the one in your stomach) on a McD's hamburger???




And last but not the least, my power point presentation

Digestive System short 2019 from Andrea Sánchez del Rio


 I hope the post will be useful.. Study a lot, please!!!

Once There Was A Jack, A Charlie and an Alfred Diffusing In Water

Here I am again, people,!!! Let's get ready for the final integrative test!!!This is the video we saw some classes ago to help you understand the relationship between surface area and volume. This is a key concept to understand absorption in every part of our bodies.

So, less talking and more doing!!!
A biologist will show this ratio with an interesting lab experiment



This is the other video about the biochemical implications of this ratio at cell level





 Thr great Maxi Cochello designed a home experiment to prove the same point: which absorbs the most, a wiping cloth or a sponge?

I'm also including my  powerpoint presentation on transport IN and OUT of the cells for you to use as a review
  
TRANSPORT IN CELLS
 

Transport in cells 3rd from sdelrioandrea

As you can remember, we discussed that poor Leo Dicaprio died in Titanic because of 1) the loss (=perdida) of heat to the water by a diffusion process and because 2) all the water in his cells froze and the enzymes inside the cells stopped working because of the low temperature...



It was sad, wasn't it? and now, off with the watery romantic eyes and in with the funny stuff.

Shame on you, Rose, you selfish cow!!!

and ... do you remember Rose´s last words in the trailer?

The Mythbusters proved James Cameron WRONG!!!



I have a special 10 for the person that can tell me if Jack could have really gone to the bottom of the ocean or could have floated after dead (with a scientific explanation, of course!!!)

And for the girls only... the moment when heat diffuse from Zac's body into Tess's cold body to save her life...




and now let's get a bit more serious...


(just the information we discussed in class!!!)

And another one from BBC




Study a lot for the test on FRIDAY, November 22nd please, because I wouldn't like this to happen:
