Procedure Part A: Comparing Disruptions

●With your partner, read about your
assigned ecosystem. Take notes on
this table

●

THEN: exchange information with
your group and complete the table
for the other ecosystem your group
members read about

Complete la lectura asignada y tome notas. Luego, comparte estas
notas con tu mesa.

Open Ended

What was the disruption for your assigned area?

Open Ended

How long did this disruption occur (timeframe)?

Poll

Would you say your assigned ecosystem was resistant or resilient?

• Resistant - it didn't allow the changes to disturb the ecosystem much

• Resilient - Major changes happened but my ecosystem bounced back

• Neither - my ecosystem is close to being collapsed

Procedure Part A continued

#3 Discuss with your group:

How were the disruptions to the ecosystems different?
○ ¿En qué se diferenciaron las alteraciones de los ecosistemas?

•

What evidence do you have that each ecosystem is resilient?
○ ¿Qué evidencia tienes de que cada ecosistema es resiliente?

Lost Sea”

●

Multiple Choice

What are the main causes of the Aral Sea crisis?

• Excessive irrigation and diversion of water from the rivers

• Climate change and natural evaporation

• Industrial pollution and waste dumping

• Overfishing and depletion of fish stocks

Multiple Choice

How has the Aral Sea crisis impacted the local communities?

• The Aral Sea crisis has had no impact on the local communities.

• The Aral Sea crisis has had a devastating impact on the local communities.

• The Aral Sea crisis has improved the living conditions of the local communities.

• The Aral Sea crisis has only affected a small portion of the local communities.

Multiple Choice

What are the ecological consequences of the Aral Sea crisis?

• Shrinking of the sea, loss of biodiversity, desertification, increased salinity levels

• Decrease in agricultural productivity, reduced water availability, increased soil erosion

• Rise in sea levels, increased rainfall, expansion of wetlands

• Increase in fish population, decrease in water pollution, improved water quality

Multiple Choice

What is the main reason for the shrinking of the Aral Sea?

• excessive irrigation for agriculture

• industrial pollution

• natural evaporation

• climate change

Multiple Choice

How has the Aral Sea crisis affected the fishing industry in the region?

• The Aral Sea crisis has severely affected the fishing industry in the region.

• The Aral Sea crisis has only slightly affected the fishing industry in the region.

• The Aral Sea crisis has actually improved the fishing industry in the region.

• The Aral Sea crisis has had no impact on the fishing industry in the region.

Multiple Choice

What is the current status of the Aral Sea?

• Fully restored

• Thriving ecosystem

• Unaffected by human activity

• Severely degraded

Multiple Choice

What is the problem in the Aral Sea?

• It’s full of oil.

• It’s getting bigger

• It’s getting smaller.

Multiple Choice

The Aral sea started to shrink mainly due to

• river water was diverted

• lack of rainfall

• used the lakes water for farming

Multiple Choice

How has the Aral Sea crisis affected the climate in the region?
