Why do scientists look for water when looking for life? What are the properties of water that are important for sustaining life? Could there be life on other planets without water?

Ever since NASA was established in 1956, humans have been looking for life beyond Earth. The effort in looking for life elsewhere in our solar system involves looking for the presence of water. Why do scientists look for water when looking for life? What are the properties of water that are important for sustaining life? Could there be life on other planets without water?

What do people know that you may not? Why have certain decisions been made? Why are things happening the way that they are?At the actual meeting, only Ham and McCormack spoke, Why did everyone else remain silent? Why did they (or you) treat the strike foam in such a cursory fashion?

Topic/Question 1

What do people know that you may not? Why have certain decisions been made? Why are things happening the way that they are?

There were some critical decisions made during this meeting about the foam strike that occurred at the beginning of the mission, but why were these decisions made?

At the actual meeting, only Ham and McCormack spoke, Why did everyone else remain silent? Why did they (or you) treat the strike foam in such a cursory fashion?

What’s your perspective? Do you have serious concerns about the foam? Why or why not?” Start your response by introducing your character and providing a description of your role.

NASA that impacted the decisions made. You want to obtain information that is not accessible solely from the perspective of your role.

How would construct validity be applied in this example, and why would it be important to prove that validity?

Suppose a NASA task force is reviewing a final draft of an accident/incident report, and you have been tasked with determining whether the conclusions presented in the final draft are in line with the data/findings presented within the report.

Why would construct validity be part of your thought process in completing such a task?

Now consider a specific real world example in which NASA needed to investigate an accident/incident to determine the cause.

How would construct validity be applied in this example, and why would it be important to prove that validity?

Note: No duplications allowed – you must choose a real world example that has not already been described in the discussion. The earlier you post, the more choices you’ll have

What is described as the principal threat to biodiversity as the global economy and human population grows? Is economic growth necessarily bad for our planet? What points suggest that economic growth can benefit biodiversity?

SLP 2

You learned about the negative impact of economic growth and human utilization of resources that can lead to global climate change and extinction.

In your Case Assignment, you reviewed many pieces of evidence and developed your own conclusions about the relationship between human activities and global climate change.

Now review the conclusions that have been drawn by NASA regarding this information at NASA Climate Part I:

A Closer Look at the Evidence For the first part of this assignment, answer these questions using the NASA website: Describe the graph on the NASA website.

What does it show us about the concentration of CO2 in the atmosphere? According to the following site (the United Kingdom's

National Meteorological Service), what recent event contributed to the rising carbon dioxide levels? Met Office The supporting data on climate change are grouped into different categories on the NASA website.

How are these groups labeled? Is there agreement on these categories between the NASA website and the UK website (Met Office).

If not, how do they differ? Select the “Effects” tab at the top of this web page: https://climate.nasa.gov/evidence/.

Summarize the effects of climate change listed here in one paragraph.

Be sure to address the effect of climate change on our weather and water resources.

Part II: How Can Economic Growth Become Part of the Solution?

Read the following article then answer the questions below: Saltre, F. & Bradshaw, C. (2019). Are We Really in a 6th Mass Extinction? Here’s the Science.

Science Alert. https://www.sciencealert.com/here-s-how-biodiversity-experts-recognise-that-we-re-midst-a-mass-extinction Now answer the following questions regarding economic growth and climate change discussed in this article in paragraph format.

How does economic growth negatively impact other species?

What is described as the principal threat to biodiversity as the global economy and human population grows? Is economic growth necessarily bad for our planet? What points suggest that economic growth can benefit biodiversity?

Conclude your summary by drawing connections between economic growth, climate change, habitat loss, and biodiversity. Required Readings: https://climate.nasa.gov/evidence/ https://www.metoffice.gov.uk/weather/climate-change/causes-of-climate-change https://climate.nasa.gov/evidence/

How many major mass extinction periods are listed here? Follow the links from that page to learn more about each period. What caused each, and which major groups of species disappeared from each period?

ECOL Mod 2 Case

Case Part I: Geologic History of Earth

The first part of this assignment requires that you consider the history of extinction on our planet.

From the Sam Noble Museum, answer the following questions:

How many major mass extinction periods are listed here? Follow the links from that page to learn more about each period. What caused each, and which major groups of species disappeared from each period?

Conduct a library or web search and find two examples of an extinct species (can be plant, animal, insect).

Explain when each species became extinct and the suspected reason(s) that led to the extinction.

Case Part II: Global Climate Change

Scientists have concerns that human activities are changing our environment at rapid rates that could result in a sixth mass extinction. Let’s examine the evidence:

Review the “Recent, Past and Present” section from Mass Extinctions.

Also review the following link from the NASA website: https://climate.nasa.gov/causes/

Define greenhouse effect. Describe which gases are important to the greenhouse effect.

What were listed as human activities related to greenhouse gas production from each link?

How do humans contribute to both climate change and major extinction events?

Some scientists think that human activities may be contributing to a sixth mass extinction event.

What specific evidence do they site for this possible event? (you may need to conduct additional research to support your findings).

Part III: Drawing Conclusions

Now provide a summary that explains what conclusions you can make for yourself based on the evidence provided and what you now know about the geologic time scale of the history of the Earth.
