There should be a 1 page report at the end of each worksheet centered around the question given. The worksheets are very short. Please see attatchments below. You will need to use the  links provided to complete these labs.

Lab 3:

In this lab, you will gather data about CO₂ emissions using the National Oceanic and Atmospheric Administration Web site (Earth System Research Laboratory, n.d.) to help you write up a scientific report centered around known phenomena of CO₂ emissions, related to the following question:

• Would you expect to see an increase or decrease in CO₂ emissions in the data over the past 40 years? Why? Sources of CO₂ Emissions Follow link https://class.aiuniv.edu/_layouts/MUSEViewer/MUSE.aspx?mid=MU17320

Lab 4:

In this lab, you will see the time progression of impacts associated with either coal-fired or nuclear power plants for electricity generation to help you write up a scientific paper that centers on the following:

• Given that the current 2 primary sources of electricity generation are coal and nuclear power plants, which of these sources is better for human sustainability?

Analyze Energy Sources Lab

Everything people do in their daily lives involves the consumption of resources—particularly energy. With respect to energy, electricity is one of the most important resources consumed and also one of the highest in demand. Traditionally, fossil fuels such as coal, natural gas, and oil have dominated the U.S. energy mix; however, as it is well-known, carbon-emitting energy sources are very detrimental to the environment and are contributing to global warming. Fortunately, alternative energy resources such as solar, wind, hydro, and geothermal power are becoming more efficient and prevalent in today’s energy economy.

Lab 5:

In this lab, you will determine how an invasive species—the zebra and quagga mussel—affects other species in the freshwater lake. Use the animation to help you come up with an answer to the following:

• Why do you see increases and decreases in the invasive species population?
• What are the implications associated with these alterations to the ecosystem as a whole?

The Effects of Zebra and Quagga Mussels Introduced into a Freshwater Lake

As you have learned, population dynamics are caused by the biotic potential of the population and the effects of environmental resistance. When there is minimal environmental resistance impacting a population, it will exhibit a population explosion. One reason for minimal resistance could be factors that no longer regulate a population (e.g., predator decline or resource increases). Another reason for a population explosion is the introduction of an invasive species. Invasive species are species foreign to an ecosystem and are not immediately regulated by the environmental restraints of the particular ecosystem that they invade. This in turn allows their populations to grow seemingly uncontrolled and to displace other indigenous populations. Examples of such an invasive species into North America are dreissenid mussels, commonly known as zebra and quagga mussels. Their introduction into the Great Lakes has caused economic hardship and a reorganization of the ecosystem. This has led, in part, to pollution-causing effects that can be linked to an alga known as Cladophora.

Ecosystems are webs of intricately balanced interactions, what happens when a new species is introduced that uses a disproportionate share of the ecosystem’s resources?
