Here's what you need to do:

1. Review the concept of density at density.


2. Copy and complete the chart that organizes the following data about the 5 crowns: all of the crowns look identical and have a volume of 180 cm3. The 5 crowns have the following different masses: 1890 g, 486 g, 1404 g, 3474 g, and 2034 g.


3. Calculate the density for each crown using the formula:

Density equals mass divided by volume. [ D=M/V ]

Record the density for each crown in the chart.


4. Be certain that your chart contains complete headings for each column. Include the unit of measurement for mass, volume, and density.


5. Examine the chart "Density of Common Substances."


6. Answer the Questions to help clarify your thinking.


7. Summarize your findings in a paragraph or two (a short essay) persuading the king that you have correctly identified the real gold crown using scientifically accurate information.

*Before you begin to write, use a graphic organizer to order your ideas in a logical way. Be certain to use supporting evidence from your density calculations and the chart "Density of Common Substances."
