Human impacts on the environment: Group assignment

Some human activities affect negatively on the environment causing problems in food production, habitat destruction and pollution.

Let´s investigate some of them:

1- Global warming
2- Deforestation
3- Acid rain
4- Use of fertilisers:Eutrophication
5- Monoculture
6- Plastic pollution

You are divided into the following groups for this assignment:

GROUP 1: Global warming                

  • Anania M.
  • Criniti G.
  • Kreutzer O.
  • Lusso F.

Group 2: Monoculture

  • – Vidal F
  • Maestro M
  • Mayol B

Group 3: Acid rain

  • Braun S
  • Manwani V
  • Campion L
  • Méndez M

Group 4: Eutrophication   

  • Landolfo V
  • Villegas
  • Roggero

Group 5: Deforestation   

  • Galmarini
  • Segura
  • Vago
  • Villafañe

Group 6:Plastic pollution 

  • P. Muñiz J.
  • Montanelli
  •  Müler
  • Leguizamón

Task: Create a presentation about the environmental problem. You should include:

1)  causes and effects

2) possible solutions.

3) one example in Argentina.

4)  one example from abroad.

On Tuesday October 2nd, you will show your work in class.

Transport in humans

A multicellular organisms , such as a person,  needs a transport system to move substances around the cells. In the human body, a transport system consists of:

  • The heart
  • Blood vessels: arteries, veins and capillaries
  • Blood: components and functions

 

The heart and circulation

  • Read pages 4 and 5 from THIS LINK and play the animations.
  • How does the heart work? Watch the video!

  • INVESTIGATING HEART DISEASE: click on THIS LINK to learn about the angiogram and the ECG.

Blood vessels

  • Let´s learn more about arteries, veins and capillaries.

The structure of each of them is related to the function.

READ HERE!

Blood

  • Take a look at the worksheet we did in class and click on THIS link!

Enjoy! 🙂
