Will we have enough affordable energy in the near future? What will we do for the long term? The US Energy Information Administration is an independent agency that gathers and analyzes data on energy supply and demand. When they issue a new report, the information is often carried in the news media.

First:

1. 1. Review

The Supply and Demand and Improving Efficiency sections (pages 12-23) from What You Need To Know About Energy

1. Read

The LA Times article by Catherine Green, World Energy Use To Jump by 2040

The Bloomberg article by Morning Zhou, World Energy Consumption to Increase 56% by 2040 Led by Asia

The PowerPoint presentation summary of the International Energy Outlook report from the US Energy Information Administration, the basis of the LA Times and Bloomberg articles

Then, submit the following:

1. A completed Your Science Toolkit (download template) for both the LA Times and the Bloomberg articles, using the EIA PowerPoint summary and the NAS Energy booklet as the scientific sources

As you are completing the two Toolkits, pay particular attention to the reported growth rates of nonrenewable and renewable energy sources.

The two completed Toolkits should be submitted together in one document. The Science Toolkit provided in this activity provides a template for all of the required pieces.

Compose your work using a word processor (or other software, as appropriate) and save it frequently to your computer. When you are ready to submit your work, click Browse My Computer and find your file. Once you have located your file, click Open and, if successful, the file name will appear under the Attached files heading. Scroll to the bottom of the page, click Submit, and you are done. Be sure to check your work and correct any spelling or grammatical errors before you post it.

Student 2

The child that I observed was the little boy in the yellow shirt.  I learned that he both walks and climbs the stairs without help.  I also observed that he was able to shuffle through the pile of toys without falling over and that he was able to bend over and pick toys up without falling.  When asked if he can find a pilot for his helicopter and if he can find a boat he points in both cases, although he does go to play with the boat a moment later.  His language development is still at a level where he calls the helicopter a plane, but he does say a couple of two word statements.  Those statements are “it flies” and “big boat”.  When asked who could ride in the boat, he grabs the closest toy which is a horse and he calls it a horse.  He also points to a turtle decoration and says turtle.  He spends some time watching the other little boy play, but also spends time sitting near him playing. When the boy in green tries to take his boat, he stands up and taking the boat with him goes to the far side of the play area.  He pointed when asked questions more than he spoke.

Other performance-based assessments that I would like to complete would be ones that would help me to fill in the checklist better as it would give a better picture of what his strengths and weaknesses are.  I would choose to do these because by covering most if not all of the checklist it will be easier to make better conclusions about if his development is on track.  Games could be introduced to the play session to observe different skills, as could a snack time, and clean up time and these could be further assessed using a numerical rating scale to get a better idea of where his development is along a scale (Wortham, 2012).

Some of the advantages of performance based assessments are they a good tool for monitoring young children’s development, they are in context and can be incorporated into existing activities, they can be adapted to each child and their circumstance, and they can be ongoing (Wortham, 2012).  Some of the disadvantages of these assessments are that they are subjective, the teacher needs to be skilled to interpret them correctly, they can be time consuming and complex, and there are concerns about the validity and reliability of them (Wortham, 2012). I feel that with proper training the advantages outweigh the disadvantages to using performance-based assessments with young children.

 

Assignment 2: Global Warming: Cause and Mitigation
Due Week 9 and worth 160 points

Among the most controversial topics in physical science, global warming has received a great deal of attention during the past decade. Given its great impact on both humans and the environment, lawmakers and scientists must heavily weigh the information that they are presented. Explore this debate in more detail by evaluating both the scientific basis of this phenomenon and the human role in global warming.

Write a three to five (3-5) page paper in which you:

1. Compare and contrast natural versus anthropogenic climate changes. Include at least two (2) specific examples of each.
2. Take a position as to whether or not global warming is taking place. Provide three (3) lines of evidence to support your position.
3. Assess two (2) current mitigation strategies for global warming, such as carbon sequestration, carbon taxing, clean coal technology, higher fuel efficiency standards, and so on. Analyze the effectiveness of this mitigation strategy, as well as its potential costs and policy implications.
4. Speculate on the policy changes that you would propose to help stabilize global climate and determine the business sectors or nations that would be held to more strict standards if you were to implement your proposed policies.
5. Use at least four (4) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.

Your report must follow these formatting requirements:

• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
• Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

The specific course learning outcomes associated with this assignment are:

• Apply concepts in physical sciences to evaluate current trends and issues in the modern world.
• Describe the physical processes influencing climate and weather.  
• Use technology and information resources to research issues in physical sciences.
• Write clearly and concisely about physical sciences using proper writing mechanics.
