In biology, we are doing a research project on teeth

Lab activities

A1 and A2

a) How many teeth do you have on your jaws?


b) How many of these are incisors?

4 in each jaw.

c) How many are canines?

2 in each jaw

d) How many are premolars and molars?

4 premolars and 4 molars in each jaw


a)Do you have filling in your teeth? Wich?

In none of them


a) Take a bite out of an apple, what teeth did you use?

The incisors

b) How are they adapted for their function?

They are sharp and well positioned


a) Chew an apple carefully, what teeth did you use?

Molars and premolars

b) They are very strong


a) What else happens as you chew?

Saliva is disolving the food to create the bolus.

Activities on the blog



2)a. When you swallow food you feel the bolus of food mixed with saliva that goes slowly from the mouth through the oesophagus.

But when you drink water, you feel a fast sense of refresh and thesalive mixed with water finally goes to the oesophagus.


When taking a portion of food from a hole meal, like biting a burger, we first bite of the piece we are going to eat, we bite it off with the Incisors, the front teeth. Then, the saliva comes in action, wetting the food, as the younger pushes it to the top of our mouths. Then, we proceed to bite the food with the Molars, the back teeth, while, at the same time, the younger moves the food around and the salive wets the food. This all happens until the food is no longer solid, when the tongue pushes the food towards the throat, where it is swallowed, with the throat contracting to push the food down.

  1. ¿Cuáles fueron los avances que aceleraron la evolución de los espacios urbanos? Los avances que aceleraron la evolución de los espacios urbanos fueron la máquina de vapor, la creación de fábricas y el trabajo asalariado, la mejora del transporte y surgimiento del ferrocarril, finalmente, más tarde surgió el motor de combustión interna haciendo uso del petróleo.

  2. Completen el esquema con las características principales de cada etapa.

Revolución industrial

  • Transformó los modos de producción

  • Transformó el transporte

Fines del siglo XIX

  • Motores de combustión por petróleo

  • Nacen las ciudades postindustriales

Ciudades postindustriales

  • Subieron mucho la población, a diferencia de los que ya estaban

Organización colonial

Este es nuestro video en organización colonial.


Nina fue la coordinadora

Juan Pablo el asesor histórico

Manolo el realizador audiovisual

De todas maneras, todos nos pudimos ir ayudando a cumplir nuestras tareas mutuamente.

Tuvimos un solo problema mayor, que fue que en pasar los vídeos al pendrive, se borró y perdió el final, creemos que el pendrive andaba mal.

Biology rap and role play

In biology, we were asked to, in our base groups, to ceate a poem and a role play of other groups.

Osmosis and Plants Cells


-cell1: hey dude

-cell2: what’s up

-cell1: nothing much, why are you surrounded by a cell wall?

-cell2: no idea man. Did you hear what happened to jack, he fell into the water, and was surrounded by it, too much water man, he died.

-cell1: he must’ve been really fat

-cell2: yeah, his cytoplasm and vacuole swelled up a lot, that’s what caused his death, apart from the water.

-cell1: but, where did he fall? Because the membrane is supposed to survive, so, it must’ve been a lot of water.

-cell2: yeah, a glass of water, poor guy.

-cell1: yeah, I think rose took a picture of him before he died, the dude was all buffed up, turgid. He got huge on his last moments.

-Cell 2: Maybe that is why I have a cell wall.


Hey there I’m Mr cell, and I want to go leave this high concentration place.

I love osmosis, water is my life, surrounded by a cell wall, i’m not fat, i fall into the water and swell up. WOOO

Sometimes I’m turgid, sometimes I’m not, all depending on how much water I’m on.

It’s not the same as diffusion, this is my own, there’s no concentration it’s water potential.

So this is life as a plant cell,

Water keeps me alive

I’m just here jamming, like the plant I am

And That was my rap


Coordinator: Manolo

Facilitator: Uva

Support: Nina

We found it easy, because everyone worked perfectly. We were all happy with our positions and we worked fine. Besides, Nina had already created a beat so the rap was easy to create.


We were also asked to assess one of the groups, I chose Gonzalo’s Sofi’s and Olivia’s group.

I think their presentation was great and very complete, but it would’ve been fun if they sang the song.
