Moreover, you need to deliver the rest of the tasks: the 4 tasks in one email please

After watching the videos, do this practice:  Práctica " el ecosistema ahí fuera en Alcalá". It is in Spanish (the practice you would have done in the patio with the teacher Lucía if you had been at High School), so you can answer it in Spanish. Activities 1 and 2 are the ones you did some weeks ago, so you can use the same data or observe more to complete it. Then, complete the rest of the activities. Print the worksheet and answer the questions in the same paper or just copy the number of each activity and answer them in your notebook. You can ask any doubt about this in the on line class on Thursday. 

Please name the file like this: " Name. First letter of your surname. Práctica ecosistema". Example: " María.A. Práctca ecosistemas". Try to scan the whole activity in a PDF file with a scanner, if you have it or with an app in your mobile phone called "image to PDF converter" . There are many with the same name, download the one it has 4,7 stars in the comments of users. It is really useful and it really easies my job. 

TASK 2. Audio loss of equilibrium in the ecosystems

Read page 194, 195 and 196. Then listen to this  audio with Beth's voice and answer the following  questions in your notebook: 

1. How can we solve the problem of zebra mussels?
2. How can we reduce monoculture?
3. In which two ways can we reduce the amount of forest fires?
4. Which two things could reduce the rubbish problem?
5. What could governments do to reduce oil spills?
6. What could tankers do to reduce oil spills?

If you have a lot of problems with understanding Beth's accent it here you have the transcript of the audio, for you to read and listen at the same time. Please, write at the end of your answers if you had to read the trasncript or not, it is just for me to know it, it won't affect your mark. 

Please name the file like this: " Name. First letter of your surname. Loss.equilibrium.ecosytems"

Do actvity 2 page 196, writing 2 paragraphs at least about the impact of human activity on the environment you live. Please name the file like this: " Name. First letter of your surname. Human impact where I live"
