Question

plz help, due tomorrow ,

1.2 which properties of aluminum might concern you if you had to use the aluminum tableware that Napoleon employed to impress his guests?

1.3 what does the scientific method start? what is the first step?
1.4 use the web to determine the amount of aluminum used in the United States in a single year. What is the primary use for this material?
1.5 use the web to find current prices offered for aluminum for recycling. is there variation in the price based on where in the United States the aluminum is returned?

1.6 use the web to determine the differences in the amounts of aluminum recycled in states where there are deposits on aluminum cans versus states where recycling is voluntary. what is the most relaible way to estimate this value? what uncertainty is there in the estimate?

thank you

Explanation / Answer

Ans.

1.2 Al tableware would be very susceptible to rapid oxidation and would have to be
polished frequently.

1.3 you need to come up with a scientific research project or science fair project. One of the obvious challenges is to find an idea for the project. Also, you needscience involved, so you will need to apply the scientific method somehow. The scientific method can be stated several ways, but basically it involves looking at the world around you, coming up with an explanation for what you observe, testing your explanation to see if it could be valid, and then either accepting your explanation (for the time being... after all, something better might come along!) or rejecting the explanation and trying to come up with a better one.

Scientific Method Steps

The exact number of steps to the scientific method depends on how you break up the steps, but here is an overview of the basics:

1.4 The are radical changes in the amount of aluminum produced in the US as more
production is shifted out of the US. Utilize a world wide web search engine to
acquire the reference. Primary use for the material is transportation.

1.6 Recycling rates have steadily declined in recent years; utilize a world wide web
search engine to acquire the most current reference.
